Additionally, networks can be constructed from structural data (T1 or T2 images). One popular strategy for doing so is to generate ‘structural covariance matrices’ ( , 2012; ). The weight of the edge between regions and is usually defined as the population-level covariance of and ’s cortical thickness (or some other structural measure). Accordingly, structural covariance matrices are typically defined at the group level. However, recent studies have extended this approach to the level of individual subjects by computing the covariance (or correlation) between ensembles of morphological metrics defined regionally (e.g. , 2018). In principle, one could define nodes as the smallest possible unit of interest. In neuroimaging, this corresponds to voxels or surface vertices (grayordinates). However, voxel-wise networks are large (on the order of 10 5 number of nodes) and can present computational challenges. Additionally, many voxels and vertices connect similarly to the rest of the brain, suggesting that those voxels could be merged together without a loss of much information. There are numerous approaches to take to defining nodes, including functional specificity, topographic organization and connectivity ( Felleman and Van Essen, 1991 ; Van Essen and Glasser, 2018 ). However, in practice, most studies elect to parcellate the cerebral cortex into, roughly, hundreds of non-overlapping parcels (e.g. regions of interest) by assigning every voxel/vertex to one parcel. There are, of course, many strategies for generating these parcellations. Early studies took advantage of existing divisions of the brain into regions based on anatomical (e.g. Automated anatomical labeling; Rolls et al. , 2020 ) or cytoarchitectonic information (e.g. Brodmann areas; Sporns, 2011 ). While these parcellations continue to be used, they have been largely supplanted by data-driven approaches in which parcels are defined using functional connectivity data ( Power et al. , 2011 ; Shen et al. , 2013 ; Gordon et al. , 2016 ; Schaefer et al. , 2018 ) and sometimes other microstructural properties (see Glasser et al. , 2016 ). The aim of these approaches is to generate functionally homogeneous parcels such that the voxels assigned to any given parcel exhibit similar patterns of connectivity with respect to the rest of the brain. Additionally, parcels are usually defined to be spatially contiguous and should be generalizable, so that when they are imposed on new brains, the resulting parcels are still functionally homogeneous. Homogeneity, as it is discussed here, does not refer to the blood-oxygen-level-dependent (BOLD) signal, but rather is assessed using similarity or distance-based metrics on measures such as functional or anatomical connectivity, cytoarchitectural properties or topography. Recently, it has become clear that parcels generated from pooled, group-averaged functional connectivity may systematically distort individual features ( Braga and Buckner, 2017 ; Gordon et al. , 2017 ; Gratton et al. , 2018 ), igniting new efforts to generate flexible parcellations that can adapt group-level parcels to individual brains ( Chong et al. , 2017 ; Bijsterbosch et al. , 2018 ; Kong et al. , 2019 ; Mejia et al. , 2020 ) by leveraging data collection tools such as multi-echo fMRI ( Lynch et al. , 2020 ). Using individual parcellations may be particularly beneficial for social cognitive network neuroscience research, given that its goal is to estimate individual differences in social behavior from brain networks (see Mwilambwe-Tshilobo et al. , 2019 for a relevant example). In network analyses, parcels are treated as nodes. In general, the choice of parcellation will impact the properties of a network such that two different parcellations of the same brain can exhibit contradictory properties or provide misleading summaries of interregional connectivity ( Wang et al. , 2009 ; Zalesky et al. , 2010 ). Since there is, generally, no ground truth by which to assess the validity of any parcellation, it is difficult to unambiguously and objectively determine which parcellation is ‘best’. Even measures of parcellation quality, e.g. the average homogeneity of parcels, can be biased by the number and size of parcels, with finer parcellations exhibiting greater levels of homogeneity ( Gordon et al. , 2016 ). Further complicating this process is the fact that parcel boundaries vary across conditions ( Salehi et al. , 2020 ) and time ( Iraji et al. , 2019 ), thereby resulting in there not being a universally optimal parcellation. To increase the reliability and replicability of their parcellations, some of the more widely cited parcellations are those that were generated (and validated) using large datasets (e.g. Power et al. , 2011 ; Yeo et al. , 2011 ; Schaefer et al. , 2018 ). For example, Yeo and colleagues (2011) used resting-state data collected from 1000 brains to identify network parcellations. They generated their initial network structure from a subset of 500 brains and replicated the structure across the second set of 500. Using this approach, they ultimately identified (and cross-validated) 17 putative systems that largely divide seven core cognitive domains—visual, somatomotor, default mode, limbic, dorsal attention, ventral attention and frontoparietal ( Yeo et al. , 2011 ). At present, one of the most widely used atlases was developed by Schaefer and colleagues (2018) using a multi-modal approach and data from nearly 1500 participants. Similar to the approach by Yeo and colleagues, the data were divided in half to create a discovery and replication sample. Rather than a fixed number of nodes, this study resulted in a multiresolution network parcellation comprising between 100 and 1000 parcels (in increments of 100), each of which could be mapped to one of 17 validated brain systems, analogous to those in the Yeo atlas ( Yeo et al. , 2011 ). Importantly, the parcels generated by Schaefer et al. were more functionally homogeneous compared to a set of comparable parcellations (for discussion, see Schaefer et al. , 2018 ), including the well-known Gordon atlas ( Gordon et al. , 2016 ). Although these differences emphasize the importance of standardizing approaches, they also demonstrate that using a parcellation that was defined in a rigorous manner may reduce the likelihood of spurious findings (for discussion, see Arslan et al. , 2018 ). Since nodes vary across conditions ( Salehi et al. , 2020 ), another approach is to define the nodes of interest through a task-based localizer ( Chai et al. , 2016 ; Schmälzle et al. , 2017 ; Hughes et al. , 2019 ). Although such approaches are less common, they may provide a more targeted and hypothesis-driven method for modeling resting-state and especially task-based functional connectivity. For example, one study found that global vs specific task-defined parcellations had dissociable effects in predicting task performance on language tasks ( Bansal et al. , 2018 ). Two recent social neuroscience studies have also used this approach. One compared functional connectivity within the default-mode system to connectivity derived from a task-based localizer (e.g. Hughes et al. , 2019 ) and found that only the latter predicted social behavior (theory of mind performance). Another study found that connectivity between nodes in a theory-defined ‘mentalizing system’ during a social exclusion task predicted aspects of adolescent males’ friendship networks ( Schmälzle et al. , 2017 ). An important future direction for social cognitive network neuroscience research will be to evaluate the effectiveness of using a data-driven vs theory-driven approach in predicting social behavior. A second, but oftentimes less explored, source of variation in network organization is how one determines the presence or absence of a functional connection and its weight (the edges between pairs of nodes). In general, functional connectivity is defined as a measure of statistical dependence between activities recorded from distinct neural sources ( Friston, 1994 ; Sporns, 2010 ; Figure 1A–C ). In practice, however, resting-state functional connectivity is almost always calculated as a temporal correlation of activity, i.e. a Pearson correlation ( Smith et al. , 2009 ). Note that in studies of task-evoked connectivity, additional preprocessing steps need to be performed prior to computing the correlation. Specifically, activations driven by presentation should be regressed out so that they do not artifactually drive correlations ( Cole et al. , 2019 ).Apart from MRI data, networks can also be constructed from scalp and intracranial electroencephalography (sEEG and iEEG; e.g. , 2019; , 2019; , 2021), MEG (e.g. ., 2011; , 2021) and fNIRS (e.g. , 2013; , 2018) data. These methods record brain activity using electrical, magnetic and spectral properties. While some clinical conditions require placing recording electrodes directly onto the exposed cortical surface, more commonly EEG, MEG and fNIRS record signals on the scalp and generally offer poorer spatial resolution compared to fMRI. However, they acquire data at a frequency that is orders of magnitude faster than that of fMRI, making it possible (in principle) to detect and characterize changes in network structure with sub-second precision. Network nodes can be defined either as the sensors themselves, or, following source reconstruction, anatomically, which makes it possible to use familiar parcellation-based approaches for defining network nodes. The improved temporal resolution along with the oscillatory basis of EEG and MEG signals have contributed to the widespread use of phase-based measures of synchrony to define edge weights, e.g. phase-locking values. The spectral content of EEG and MEG is much broader than that of fMRI; it is common to define connectivity within specific canonical frequency ranges. Defining nodes
Defining edges
Functional network construction and canonical properties of brain networks. Functional networks are constructed by extracting fMRI BOLD time courses from voxels, grayordinates or parcels (A) and computing their temporal correlation (B). Note that, in principle, other measures of statistical dependence can be substituted, e.g. that account for nonlinearities. This process is repeated for all pairs of neural elements, usually defined to be parcels. The result is a correlation matrix that is referred to as a ‘functional network’ (C). The network can be viewed in anatomical space by drawing a circle (node) at the spatial center of each parcel and linking connected nodes by lines (edges). The resulting network can be analyzed with tools from network neuroscience. These tools can (D) track the flow of information through the network by studying paths, (E) identify influential nodes based on the number of connections (a node’s degree), (F) assess the contribution of the brain’s spatial embedding on its network architecture (in general, brain networks prefer to form low-cost, short-range connections rather than costly long-distance connections) and (G) identify functionally specialized sub-networks known as modules or communities.
Other studies have used temporal precedence measures to establish pseudo-causal relationships between time series, e.g. Granger causality and transfer entropy ( Smith et al. , 2011 ; Holper et al. , 2012 ; Maki-Marttunen et al. , 2013 ; Ribeiro et al. , 2021 ). Broadly, these measures test whether the past activity of one region helps predict the future of another region’s activity above and beyond what its own activity can predict. While temporal precedence measures like Granger causality and transfer entropy hold tremendous promise in revealing directed interactions between brain regions, their accurate estimation requires large amounts of data and, in the case of transfer entropy, necessitate the binarization of time series or force the user to make assumptions about the underlying distribution of brain activity. Finally, care must be taken in interpreting these measures. While their application to spike trains and cellular levels lead to straightforward interpretations, the slow and serially correlated fMRI BOLD signal (itself an indirect measure of population-level activity) may obscure true causal relationships.
In general, any bivariate measure of statistical dependence can be used to assess the presence, absence and/or weight of an edge. However, the decision to use a particular measure should be motivated by the experimental paradigm. For example, PPI, which assesses the effect of tasks influence the coupling strength between two regions ( Friston et al. , 1997 ; O’Reilly et al. , 2012 ), should only be used for tasks, and for maintaining continuity with extant literature. Introducing a novel measure when an existing measure is capable of capturing the desired effect makes it challenging to compare the present results against those from previous studies and may have the unwanted effect of confusing readers.
As with node definition, how one defines a functional connection has implications for the organization of the inferred network. Different measures also have the capacity to summarize different modes of coupling between network nodes. For instance, the commonly used Pearson correlation assesses the linear relationship between the activities recorded from two nodes. However, if that relationship is nonlinear, the Pearson correlation might be misleading. In contrast, measures like mutual information may be better suited for capturing generic, nonlinear relationships between nodes ( Smith et al. , 2011 ; Pervaiz et al. , 2020 ).
Figure 2 provides an overview of the steps discussed in this section. In summary, social cognitive network neuroscience should carefully consider how to reduce variability in node selection and in how functional connectivity is calculated. One potential way to do this would be to build on existing models from the field of network neuroscience, such as using well-studied network parcellations (e.g. Schaefer et al. , 2018 ). In addition to providing a clearer foundation upon which the field can evolve, such an approach would provide more domain-general insights into social neuroscience.
Constructing brain networks from neuroimaging data. Graphical depiction of the suggested pipeline for constructing brain networks. Each step is associated with multiple user-defined parameters and options, whose strengths and weaknesses are discussed in detail in the review. Several choices (e.g. selecting the dataset to use in the first step) will largely be dictated by the research question. The steps are presented in sequential order but are not intended to be prescriptive. Rather, they are intended to offer a summary of the key steps discussed in this review and are presented for convenience and clarity. Constructing a network begins with data selection (Step 1). Traditionally this meant collecting data under different conditions (while performing a task, while passively listening/viewing audiovisual stimuli or in the absence of explicit task instruction). Recent initiatives, however, have made high-quality data publicly available, organized according to field-defined standards and processed via distributed computing. After data selection, data undergo basic preprocessing steps (Step 2; alignment, intensity normalization, nuisance regression, frame censoring, etc.). This procedure results in ‘cleaned’ voxel/vertex time series. In most network analyses, the dimensionality of these data is reduced via a parcellation step (Step 3), in which voxels/vertices are aggregated into parcels. Parcels may be determined a priori based on existing atlases, meta-analytic activation maps or using localizers to co-locate similar functional territories across individuals. The final step (Step 4) is to establish whether a connection exists between pairs of parcels (nodes). In human neuroimaging (especially of the resting brain), the convention is to estimate connection strength based on the extent to which two regions’ activity time courses are correlated with one another. Other measures (e.g. mutual information, spectral coherence and Granger causality) are discussed in the review.
Brain network analyses necessarily shift focus away from measuring activation in specific brain regions and instead emphasize on how different parts of the brain interact with one another as components of distributed networks. This increasingly global view allows for network neuroscientists to identify the overarching principles by which brains are organized and operate. Inspired by advances in other scientific disciplines ( Watts and Strogatz, 1998 ), early work in network neuroscience focused on ‘small-worldness’ ( Sporns and Zwi, 2004 ; Bassett and Bullmore, 2006 ), which refers to the propensity for nervous systems to simultaneously exhibit locally dense (interconnected) clusters and shorter-than-expected path length. These two characteristics are thought to support specialized information processing and rapid transmission of information, respectively ( Figure 1D ). Small-world organization has been observed in brain networks across phylogeny and at virtually every spatial scale, from synaptic contacts among single cells ( Latora and Marchiori, 2001 ; Varshney et al. , 2011 ) to large-scale brain networks ( Iturria-Medina et al. , 2008 ; Muldoon et al. , 2016 ).
More recent studies have provided evidence that brain networks are organized around an exclusive set of hub regions—highly connected and highly central regions that occupy positions of influence within the brain ( Hagmann et al. , 2008 ; Power et al. , 2013 ). Because of high levels of connectivity, these regions are capable of both delivering and receiving information to and from large portions of the brain, respectively ( Figure 1E ). Moreover, these putative hubs tend to be connected to one another, forming an integrative structure known as a ‘rich club’, which serves as a backbone for efficient information transfer ( Zamora-López et al. , 2010 ; van den Heuvel and Sporns, 2011 ). Once again, hubs and rich clubs are conserved across phylogeny ( Harriger et al. , 2012 ; de Reus and van den Heuvel, 2013 ; Towlson et al. , 2013 ; Shih et al. , 2015 ).
Other studies have suggested that embedding the brain in three-dimensional space serves as an overarching organizing principle ( Stiso and Bassett, 2018 ; Figure 1F ). All things equal, long-distance connections require proportionally more material and energy, of which the brain has limited amounts, than short-range connections. Consequently, brains need to balance the formation of functionally adaptive features like efficient processing paths, hubs and rich clubs with the material and metabolic cost of forming and supporting those features ( Kaiser and Hilgetag, 2006 ; Samu et al. , 2014 ). This trade-off restricts the types of features that brain networks can support simultaneously and gives rise to a heavy-tailed distribution of connection lengths that favors short (low-cost) connections ( Ercsey-Ravasz et al. , 2013 ; Betzel and Bassett, 2018 ).
One of the hallmark features of biological neural networks—and one that is increasingly becoming the focus of network science applications in neuroimaging and cognitive neuroscience—is their decomposability into cohesive sub-networks known as ‘modules’ or ‘communities’ ( Power et al. , 2011 ; Sporns and Betzel, 2016 ; Yeo et al. , 2011 ; Figure 1G ). Modular structure is evident at all spatial scales ( Jarrell et al. , 2012 ; Betzel and Bassett, 2018 ), but it has been investigated in depth at the macroscale using human fMRI data. At rest, modules correspond closely to patterns of task-evoked activity and delineate well-known functional systems ( Smith et al. , 2009 ; Crossley et al. , 2013 ) and at multiple resolutions ( Gordon et al. , 2020 ). The correspondence of module boundaries with well-established functional systems suggests that the brain’s modular structure helps support functionally specialized processing ( Stevens and Spreng, 2014 ).
For example, partitions of functional brain networks identify modules corresponding to frontoparietal and both dorsal and ventral attention systems, which include collections of brain regions known to play central roles in control (for review, see Scolari et al. , 2015 ), top-down guided attention and processing of sensory or perceptual information, respectively ( Corbetta and Shulman, 2002 ; Vossel et al. , 2014 ). The default-mode system, one of the most widely studied collections of regions in the brain, has the unique property of being more active during resting than task states (see Raichle, 2015 ). Numerous animal studies have also identified a homologous default-mode system in non-human primates, rats and mice ( Mantini et al. , 2011 ; Lu et al. , 2012 ; Stafford et al. , 2014 ). Within humans, the default-mode system has been implicated in a myriad of functions, including receiving and conveying sensory information from the external world (for review, see Raichle, 2015 ), mind wandering ( Andrews-Hanna et al. , 2010 ) and, directly relevant in the current review, social cognition (e.g. Mars et al. , 2012 ; Meyer, 2019 ).
Modules represent collections of densely connected brain regions that, on their own, are thought to support specific cognitive functions. Complex cognition, then, is thought to arise from interactions between these modules. Accordingly, relating functional connectivity strength within and between modules during resting and/or task states to behavior has been one of the most common applications of network neuroscience, with applications in personality neuroscience ( Markett et al. , 2018 ), cognitive neuroscience ( Medaglia et al. , 2015 ) and even social neuroscience ( Schmälzle et al. , 2017 ; Wasylyshyn et al. , 2018 ; Hughes et al. , 2019 ). This approach will be discussed in more detail in a later section.
There are several key takeaways from these sections. First, the field of network neuroscience studies brain networks, which models brain regions as nodes and their pairwise functional interactions as connections. Second, small-world organization, hubs and short path length are key organizing principles of networks. Third, sub-networks or modules support specific cognitive functions. These features are expressed to some extent in virtually all brains and are thought to be critical ‘ingredients’ for healthy brain function. An important future direction for social cognitive network neuroscience research will be to apply these principles to social behavior, specifically. This includes, but is not limited to, identifying how modules and their interactions give rise to social cognition and better understanding of the roles of hubs and rich clubs in social cognition, by mediating the flow of information between modules. In the next section, we explore how network neuroscience techniques have been applied to advance our understanding of social behavior.
The limited work applying a network neuroscience approach to understanding social behavior has focused primarily on within- and/or between-module functional connectivity patterns. One of the primary modules of interest in this research has been the default mode, which is generally viewed as comprising a core aspect of the social brain ( Mars et al. , 2012 ; Meyer, 2019 ). The default mode is typically defined as a set of brain regions that are more active when the brain is at rest than during a task ( Raichle et al. , 2001 ). An emerging body of research applying network neuroscience techniques to social behavior has shown that default-mode connectivity relates to numerous aspects of social behavior, including perceived social isolation ( Spreng et al. , 2020 ), theory of mind ( Hughes et al. , 2019 ), social rejection ( Schmälzle et al. , 2017 ; Wasylyshyn et al. , 2018 ), conformity ( Wasylyshyn et al. , 2018 ), creativity ( Beaty et al. , 2019 ) and even real-world social outcomes (e.g. Falk and Bassett, 2017 ; Joo et al. , 2017 ; Pillemer et al. , 2017 ; Schmälzle et al. , 2017 ; Hyon et al. , 2020 ; Tompson et al. , 2020 ).
A recent study examined whether functional connectivity differed as a function of being socially included or excluded ( Schmälzle et al. , 2017 ). The study had adolescent males perform the Cyberball task ( Williams and Jarvis, 2006 ), a widely used manipulation of social exclusion, and evaluated whether being socially excluded during the task was associated with increased within-network connectivity in networks related to mentalizing or social pain. Mentalizing and social pain were targets of interest in this study because prior work has shown that being socially excluded is painful ( Rotge et al. , 2015 ) and elicits greater activity from brain regions associated with mentalizing (inferring other people’s mental states; Powers et al. , 2013 ). The parcellations in this study were operationalized in two ways: first, by using theory-driven approach that identified nodes associated with mentalizing and social pain using meta-analytic data from NeuroSynth ( Yarkoni et al. , 2011 ); and second, by using a data-driven whole-brain network parcellation approach. Both approaches used largely overlapping nodes: mentalizing consisted primarily of nodes within the default-mode system, whereas social pain comprised nodes from portions of the salience and cingulo-opercular systems. The results were consistent using both the theory- and data-driven approaches: when participants were socially excluded, they showed higher within-system connectivity in the mentalizing system than when they were included. No significant changes in connectivity were observed within the social pain system nor were there changes in between-system connectivity. Another study found that increased within-system connectivity in the mentalizing and social pain systems during social exclusion predicted adolescent males’ increased likelihood to subsequently comply with perceived social norms (e.g. be more or less risky while in a driving simulator; Wasylyshyn et al. , 2018 ).
An interesting aspect of the finding by Wasylyshyn and colleagues (2018) is that it demonstrated that connectivity during the social exclusion task predicted behavior outside of the scanner. Similarly, a recent study found that resting-state functional connectivity was associated with theory of mind performance ( Hughes et al. , 2019 ). Specifically, Hughes and colleagues (2019) examined resting-state connectivity within a localizer-defined theory of mind system in the default mode for young adults (individuals between the ages of 18 and 25) and older adults (individuals over the age of 65). They found that age differences in resting-state connectivity within this system predicted older adults’ theory of mind deficits on a separate task. Importantly, overall age deficits in global default-mode connectivity did not predict older adults’ theory of mind deficits, suggesting that theory-driven approaches (e.g. focusing on a sub-system or a localizer-defined system) may provide more insight into social behavior in some cases than a strictly data-driven approach. An important implication of this study is that it suggests that resting-state functional connectivity may constrain social behavior. Related to this finding, Christov-Moore and colleagues (2020) examined whether resting-state connectivity predicted empathic concern, which is essential for everyday communication and survival in the social environment ( Eisenberg and Strayer, 1987 ). The authors found that greater resting-state connectivity within the somatomotor system predicted greater empathic concern.
A burgeoning area of interest has been to use network neuroscience techniques to examine real-world social outcomes, including loneliness ( Spreng et al. , 2020 ), and the number and structure of individuals’ social relationships (e.g. Falk and Bassett, 2017 ; Schmälzle et al. , 2017 ; Hyon et al. , 2020 ). These studies have examined both resting-state (e.g. Spreng et al. , 2020 ) and task-based connectivity (e.g. Schmälzle et al. , 2017 ). With respect to the former, individuals with greater within-system resting-state default-mode connectivity had higher levels of loneliness (perceived social isolation; Spreng et al. , 2020 ). This finding has important implications for social neuroscience research because longitudinal and cross-sectional studies have found that, even when controlling for other risk factors (e.g. socioeconomic status and cognitive and physical health), loneliness is associated with poorer mental, physical and cognitive health and higher mortality rates ( Cornwell and Waite, 2009 ; Cacioppo et al. , 2010 ; Luo et al. , 2012 ; Perissinotto et al. , 2012 ; Kuiper et al. , 2015 ).
Several recent studies have also examined whether functional connectivity predicts aspects of individuals’ personal social networks—the group of people with whom an individual is socially embedded ( Joo et al. , 2017 ; Pillemer et al. , 2017 ; Schmälzle et al. , 2017 ; Tompson et al. , 2020 ). These studies primarily have examined connectivity as it relates to unique individual’s social connections ( Schmälzle et al ., 2017 ; Pillemer et al. , 2017 ; Hyon et al. , 2020 ; Tompson et al. , 2020 ; but see, Joo et al. , 2017 ). In some cases, these studies have been more qualitative, focused on identifying patterns of resting-state connectivity that predict features of an individual’s social network ( Joo et al. , 2017 ; Pillemer et al. , 2017 ). For example, one study with older adults found that their resting-state connectivity in a subcomponent of the default-mode system was positively related to the number of individuals in their network, whereas connectivity within the frontoparietal system was positively related to the number of network members with whom the older adult was close (e.g. was in contact with at least biweekly; Pillemer et al. , 2017 ).
Other studies, however, have used task-based connectivity to explore potential mechanisms underlying the relationship between functional connectivity and individuals’ social networks ( Schmälzle et al. , 2017 ; Tompson et al. , 2020 ). For example, Schmälzle and colleagues (2017) explored the possibility that changes in adolescents’ functional connectivity in response to being socially excluded might relate to the structure of their social network. They found that having greater within-system connectivity in a subcomponent of the default-mode system during social exclusion predicted having less dense (e.g. fewer interconnections among friendships) social networks.
Another potential application of network neuroscience methods to understanding social behavior is to determine whether social intelligence may facilitate non-social cognitive performance. To do this, Tompson and colleagues (2020) examined whether greater engagement of ‘social brain’ networks offsets adolescent males’ underdeveloped or underutilized inhibitory abilities to improve their cognitive performance. The two social brain systems of interest in this study were theory-defined self-referential and mentalizing brain systems. They also examined a theory-defined inhibition system. They found that adolescent males who performed better on a measure of inhibition (a go/no-go task) had stronger connectivity between the self-referential and response inhibition systems and weaker within-system connectivity in the self-referential system. Moreover, they found that the relationship between task performance and greater between-system connectivity was most pronounced for adolescents with less dense social networks. Together, these findings suggest that some aspects of social functioning may facilitate non-social cognitive function.
Although this section has focused primarily on the default-mode system, it is important to note that there are multiple other systems that play a key role in social cognition (e.g. Lamm et al. , 2011 ; Alcalá-López et al. , 2018 ; Redcay and Schilbach, 2019 ). A recent meta-analysis that classified regions comprising the “social brain connectome” ( Alcalá-López et al. , 2018 ) provides a potential overview of different “social brain systems”. Specifically, the authors identified four main functional systems, including a visual-sensory system, composed of the fusiform gyrus and superior temporal sulcus, a limbic system, composed of the amygdala, hippocampus and nucleus accumbens, and two cognitive systems: one that included the anterior insula, middle cingulate cortex and inferior frontal gyrus, and a second that included the dorsal medial prefrontal cortex, posterior cingulate cortex, precuneus and temporoparietal junction. Future work should align the social brain systems with those commonly defined by network neuroscience work to bring parsimony between the two fields.
Together, these studies provide important insights into a myriad of potential applications of a social cognitive network neuroscience approach. Identifying the brain systems and interactions among systems that give rise to social behavior is an important future direction for social neuroscience research. A social cognitive network neuroscience approach that builds on extant research from the field of network neuroscience thus may provide a more comprehensive and accurate map of the ‘social brain’ (e.g. Charpentier and O’Doherty, 2018 ; Kliemann and Adolphs, 2018 ). We next review research from the fields of personality and cognitive neuroscience that uses network neuroscience techniques to study individual differences and cognition. Our goal is to highlight potential techniques or approaches that social cognitive network neuroscience research may leverage to study social behavior.
To date, one of the most common approaches to applying network neuroscience techniques to personality neuroscience, cognitive neuroscience and social neuroscience research has been to measure functional connectivity strength within or between modules during resting and/or task states and relate it to behavior or performance ( Medaglia et al. , 2015 ; Schmälzle et al. , 2017 ; Markett et al. , 2018 ; Wasylyshyn et al. , 2018 ; Hughes et al. , 2019 ). A basic premise of this approach is that weaker connectivity within a module (sometimes referred to as dysregulation) during resting state is considered a measure of relative dysfunction in that module (for review, see Ferreira and Busatto, 2013 ). However, increased between-module connectivity during task performance is generally considered to facilitate performance because it is thought to relate to the exchange of task-relevant information between systems (e.g. Cohen and D’Esposito, 2016 ; Rosenberg et al. , 2016 ; Bassett and Mattar, 2017 ). Studies examining fixed behaviors (e.g. personality traits) have tended to relate the behavior of interest to resting-state connectivity, whereas studies examining transient behaviors (e.g. attention) have tended to relate the behavior of interest to task-based connectivity.
Personality neuroscience research has frequently used measures of within-module resting-state functional connectivity to predict a myriad of individual differences in real-life function ( Vaidya and Gordon, 2013 ; Dubois and Adolphs, 2016 ; Bassett and Sporns, 2017 ; Shen et al. , 2017 ; Markett et al. , 2018 ; Christov-Moore et al. , 2020 ), including intelligence (e.g. Song et al. , 2008 ; Cole et al. , 2012 ; Smith et al. , 2015 ), attention ( Finn et al. , 2015 ), cognitive control ( Marek et al. , 2015 ; Spielberg et al. , 2015 ) and working memory ( Cohen and D’Esposito, 2016 ). Within-module resting-state functional connectivity patterns also predict other individual differences, including mind wandering ( Wang et al. , 2018 ), lifestyle factors, including education, income and life satisfaction ( Smith et al. , 2015 ), and socially relevant traits, such as empathic concern ( Christov-Moore et al. , 2020 ) and creativity ( Beaty et al. , 2019 ). Challenges to interpreting relationships between resting-state functional connectivity and these myriad of individual differences arise due to the noteworthy heterogeneity in participants’ mental states during resting state (e.g. Buckner et al. , 2013 ; Gonzalez-Castillo et al. , 2021 ). Indeed, a recent study found that functional connectivity patterns associated with passive movie-watching better predicted participants’ cognition and emotion than did their functional connectivity patterns during resting state ( Finn and Bandettini, 2021 ). Future work is thus needed to identify the optimal states in which to measure functional connectivity patterns.
Cognitive neuroscience research, however, has explored the extent to which task-based between-network connectivity facilitates performance ( Medaglia et al. , 2015 ). The premise of this work is that greater between-network connectivity reflects the exchange of task-relevant information between systems (e.g. Cohen and D’Esposito, 2016 ; Rosenberg et al. , 2016 ; Bassett and Mattar, 2017 ). For example, Rosenberg and colleagues (2016) found that stronger functional connectivity between motor and visual systems during a sustained attention task predicted better performance than having stronger connectivity between temporal and parietal regions. Another study compared connectivity during resting state to connectivity during a motor and working memory task ( Cohen and D’Esposito, 2016 ). They predicted that since the motor task likely engaged one system (e.g. somatomotor), but the working memory likely engaged multiple systems (e.g. visual, frontoparietal and somatomotor), greater between-system connectivity would facilitate working memory, but not motor, performance. Indeed, this is what the authors found.
Another approach to using functional connectivity strength as a measure of behavior or performance is to examine the extent to which connectivity flexibly reconfigures within and between modules during both rest ( Betzel et al. , 2017 ) and task states ( Bassett et al. , 2011 ; Cole et al. , 2013 ; Vatansever et al. , 2015 ; Shine et al. , 2016 ). For example, greater variations in flexible reconfiguration of connectivity during resting state predicts individual differences in positive affect ( Betzel et al. , 2017 ). Moreover, although motor learning is accompanied by increased autonomy of visual and somatomotor systems ( Bassett et al. , 2015 ), greater flexibility during a motor learning task predicts improved performance ( Bassett et al. , 2011 ). Other work has shown that the frontoparietal system, which is involved in cognitive control (for review, see Scolari et al. , 2015 ), flexibly reconfigures connectivity to other systems to support ongoing task demands ( Cole et al. , 2013 ). These studies suggest that although there is a great deal of overlap in system configuration between resting and task states (e.g. Cole et al. , 2014 ; Krienen et al. , 2014 ; Hughes et al. , 2020 ), there are important task-specific differences. Indeed, a recent study comparing functional connectivity patterns among a group of 18 healthy individuals during resting state and also during movie-watching found that connectivity patterns became more consistent across individuals when they were watching a movie ( van der Meer et al. , 2020 ).
An important benefit of relating patterns of functional connectivity to behavior is that they have clear and measurable individual differences. Finn and colleagues (2015) examined whether functional connectivity patterns serve as ‘fingerprints’ to identify individuals (see also Miranda-Dominguez et al. , 2014 ). To do this, they examined whether individuals (among a pool of 126) could be correctly identified across scan sessions based solely on their functional connectivity patterns. In addition to finding that functional connectivity patterns were uniquely characteristic to each individual, the authors found that resting-state connectivity in the medial frontal and frontoparietal systems were the most accurate in individual subject identification, with nearly 100% accuracy. In a related study by Miranda-Dominguez and colleagues (2014) , the researchers identified unique ‘fingerprints’ (which they refer to as connectotypes) for humans and non-primates. An important contribution of these findings is that they suggest that functional connectivity ‘fingerprints’ may provide a gateway for studying individual differences. However, it is important to note that functional connectivity patterns may be conflated by inter-subject differences in node location (e.g. due to warping and distortion during preprocessing). Future work should examine this possibility.
Finally, a widely used application of functional connectivity patterns has been to identify potential biomarkers that may have clinical relevance, including for Alzheimer’s disease ( Wang et al. , 2006 ; Supekar et al. , 2008 ; Damoiseaux et al. , 2012 ), ASD ( Hull et al. , 2017 ), schizophrenia ( Garrity et al. , 2007 ; Lynall et al. , 2010 ; Venkataraman et al. , 2012 ) and depression ( Fox et al. , 2013 ; Drysdale et al. , 2017 ). A widely targeted population for this work has been with cognitively normal older adults ( Betzel et al. , 2014 ; Chan et al. , 2014 ; Wig, 2017 ; Spreng and Turner, 2019 ). In both healthy and pathological aging, older adults have weaker within-module connectivity coupled with stronger between-module connectivity during resting state ( Wang et al. , 2006 ; Betzel et al. , 2014 ; Chan et al. , 2014 ; Spreng and Turner, 2019 ; Hughes et al. , 2020 ), which have been suggested to reflect decreased functional specialization of the systems over the lifespan (e.g. Betzel et al. , 2014 ; Wig, 2017 ; Spreng and Turner, 2019 ; Koen et al. , 2020 ).
A key module of interest in this work has been the default mode (for review see Broyd et al. , 2009 ; also, Badhwar et al. , 2017 ; Garrity et al. , 2007 ), which consists of medial and lateral parietal cortex, medial prefrontal cortex, and the medial and lateral temporal cortices ( Raichle, 2015 ). Research on autism spectrum disorder (ASD), a development disorder widely associated with disrupted social function, has shown that ASD is associated with weaker resting-state default-mode system connectivity ( Assaf et al. , 2010 ; Weng et al. , 2010 ; Gotts et al. , 2012 ; Hull et al. , 2017 ), the magnitude of which relates to the magnitude of individuals’ social and communication impairments (e.g. Assaf et al. , 2010 ; Gotts et al. , 2012 ). Recent work in network neuroscience has defined three functionally distinct subdivisions of the default-mode system: two in the prefrontal cortex (the ventral medial and the dorsal medial prefrontal cortices) and one in the posterior cortex that is composed of the posterior cingulate cortex, precuneus and lateral parietal cortex ( Figure 3 ; Raichle, 2015 ). Although Alzheimer’s disease has been widely associated with disruptions in resting-state functional connectivity throughout the default-mode system ( Greicius et al. , 2004 ; Koch et al. , 2012 ; Badhwar et al. , 2017 ), some evidence suggests that connectivity within the default-mode system subcomponents differs over the course of Alzheimer’s disease ( Damoiseaux et al. , 2012 ). Thus, although the preponderance of research on the default-mode system focuses on it as a whole system, future work may benefit from disentangling its unique subcomponents.
Cortical components of the default-mode network. The activation map was obtained using NeuroSynth ( Yarkoni et al. , 2011 ) and the term ‘default mode’.
Given its unique role in social cognition ( Mars et al. , 2012 ; Meyer, 2019 ), the default-mode system has already emerged as an important target for social cognitive network neuroscience research. In the next section, we will explore some key limitations in network neuroscience research that should be considered in the context of studying social behavior. We then consider future directions for the field of social cognitive network neuroscience.
The goal of the current review was to highlight the potential impact of using a social cognitive network neuroscience approach to advance our understanding of social cognition. However, there are several limitations to this approach that should be considered. First, network neuroscience research lacks consistency in how nodes are defined in brain parcellations (e.g. Power et al. , 2011 ; Yeo et al. , 2011 ; Gordon et al. , 2016 ; Schaefer et al. , 2018 ). Variability among parcellations may contribute to spurious findings (for discussion, see Arslan et al. , 2018 ). Further complicating node selection is the fact that nodes vary across conditions, even for the same individuals ( Salehi et al. , 2020 ). To increase reliability and replicability, social cognitive network neuroscience research should consider building on existing models from the field of network neuroscience. This could be accomplished by using well-studied network parcellations (e.g. Schaefer et al. , 2018 ) that were generated (and validated) from large datasets (see also, Power et al. , 2011 ; Yeo et al. , 2011 ).
Recent concerns have also emerged regarding reliability of functional connectivity across tasks and sessions. A recent meta-analysis examining test–retest reliability of functional connectivity found relatively poor reliability across scanning sessions ( Noble et al. , 2019 ). However, an important caveat to these findings is that because reliability was measured using mean edge-level intraclass correlation coefficients, the meta-analysis was based on a small pool (about 12%) of studies examining test–retest reliability. Thus, these results should be interpreted with caution.
Finally, an important consideration in all neuroimaging research is the magnitude of the effects associated with the different analytical approaches. The effect sizes associated with functional connectivity and behavior remain largely unexplored (but see Seguin et al. , 2020 ), particularly as they might compare to region-specific activation and other measures of brain activity (e.g. Tompson et al. , 2018 ). Although some research suggests that neuroimaging doubles the amount of variance explained in some behavior (e.g. health) relative to self-report measures alone ( Falk et al. , 2011 ), meta-analyses have demonstrated that the effect sizes in cognitive neuroscience research are relatively low ( Button et al. , 2013 ; Szucs and Ioannidis, 2017 ). This limitation is confounded by relatively small sample sizes in neuroimaging work (e.g. N = 20–30; Cremers et al. , 2017 ), which have been consistently subject to criticism ( Button et al. , 2013 ; David et al. , 2013 ; Szucs and Ioannidis, 2017 ; Clayson et al. , 2019 ). Although some research suggests that at least 50 subjects may be necessary to detect reliable effects in targeted (e.g. not whole-brain) analyses ( Yarkoni, 2009 ), other work points to even higher sample sizes (e.g. N = 80) to detect reliable effects on social tasks (e.g. face processing; Bossier et al. , 2020 ). Thus, more work is needed to identify ideal sample sizes for social cognitive network neuroscience research.
A potential benefit of a social cognitive network neuroscience approach is that the availability of large datasets that measure a variety of domains of cognition, including social cognition (e.g. the Human Connectome Project; Van Essen et al. , 2013 ), provide opportunities to replicate findings within datasets (e.g. Bossier et al. , 2020 ). Moreover, they also facilitate replicability by other researchers, given the established infrastructure for accessing these data.
Network neuroscience offers a set of tools for representing brains as networks of nodes and edges. This abstraction necessarily results in a loss of detail, but allows researchers to interrogate network data at different spatiotemporal scales using a rich and ever-growing suite of quantitative methods. To date, most social network neuroscience studies have focused on brain systems and modules, with particular emphasis being placed on the default mode and its interactions with other systems and the rest of the brain. However, network neuroscience offers a much more diverse and comprehensive set of tools to interrogate networks. In this section, we highlight several tools from network neuroscience that are ( Table 2 provides links to code for these measures), at present, underutilized within the social neuroscience community. We further speculate on how these tools could be used to enhance our understanding of the role played by networks in shaping social cognition.
A summary of measures discussed in this review that concisely enumerate and articulate how to interpret different graph measures. This is not intended to be an exhaustive list, nor does it include mathematical descriptions of measures (for a more comprehensive list, see Rubinov and Sporns, 2010 ). We also direct the reader to the corresponding functions in the Brain Connectivity Toolbox (BCT; https://sites.google.com/site/bctnet/ ) that make these measurements. If that function does not exist in the BCT, we include links to an alternative source. We note that there may be other implementations of these same functions through other software packages and scientific programming languages (e.g. NetworkX in Python; https://networkx.org/ )

In the previous sections, we discussed brain systems—groups of brain regions that are cohesively connected internally but sparsely connected between one another. Oftentimes, the identities of these systems are treated as ‘given’. For instance, one might define the default-mode system based on the parcel labels that accompany the Schaefer atlas ( Schaefer et al. , 2018 ). This approach is appropriate and reasonable, but only under the assumption that systems are identical across individuals. However, recent work has shown that the boundaries of brain systems vary systematically and reliably across individuals ( Gordon et al. , 2017 ), suggesting that to study brain systems meaningfully, we need to estimate them at the subject level. Such an approach could be particularly useful for social cognitive research targeting focal brain regions, such as the fusiform ‘face’ area ( Kanwisher et al. , 1997 ).
How does one go about doing this? One solution is to algorithmically discover a network’s systems using ‘community detection’ methods ( Fortunato, 2010 ). In network neuroscience parlance, a ‘community’ or ‘module’ refers to a collection of nodes that exhibit similar connectivity profiles, usually such that nodes belonging to the same community are strongly connected to one another, a property called community assortativity ( Sporns and Betzel, 2016 ; Betzel and Bassett, 2018 ). Community detection, then, refers to data-driven methods that attempt to identify the optimal partition of nodes into communities for a given individual. In network neuroscience, the two most popular methods are Infomap ( Rosvall and Bergstrom, 2008 ), which identifies communities as groups of nodes that ‘trap’ the probabilistic flow of a random walker over the network, and modularity maximization ( Newman and Girvan, 2004 ), which defines communities as groups of nodes whose internal density of connections is maximally greater than what would be expected by chance. With either of these simple heuristics, one can identify putative communities in a network without any prior knowledge—the community boundaries are informed by the network itself. Knowing a network’s community structure is useful—it allows for ‘coarse graining’, the discovery of functionally related regions, and can be applied meaningfully to both structural and functional networks.
Another way to leverage modules and communities is to use them to determine nodal roles, e.g. identifying hubs whose connections span module boundaries and therefore may play outsized roles in mediating inter-modular communication and information transfer ( Figure 4A ; Guimera and Amaral, 2005 ). Hub regions can be detected quantitatively using the participation coefficient measure, which has a value close to unity when a node’s connections are uniformly distributed across multiple modules and zero when a node’s connections are concentrated within a single module. Interestingly, previous studies have found that hubs tend to be situated within transmodal cortex in higher-order cognitive networks ( Power et al. , 2013 ; Bertolero et al. , 2015 ) and that damage to hub regions as a result of focal lesions corresponds to widespread cognitive deficits ( Warren et al. , 2014 ). Notably, however, there are other methods for identifying and defining hubs, including their more common definitions as highly connected and highly central regions ( Figure 4A ). Collectively, these dissimilar hub definitions offer a suite of measurements for classifying and categorizing brain regions based on their connectivity patterns.
Frontiers in social cognitive network neuroscience. Network neuroscience offers a suite of computational tools, many of which are not currently widely used in social neuroscience. Here, we identify several approaches that could be used to better understand the neural bases of social cognition. (A) The definition of a ‘hub’ in network neuroscience is imprecise. In practice, hubs could be defined in a number of ways. For instance, hubs could correspond to nodes that make many connections and occupy positions of influence. They can also be defined as nodes that are central or important to a process taking place on the network, e.g. the transmission of information over a network’s shortest paths. Hubs can also be defined as nodes whose connections straddle the boundary (e.g. are bridges) between communities. Exploring the variety of alternative hub definitions has the potential to enrich social neuroscience studies. (B) Another area of interest for future studies is the decomposition of modules into hierarchies and multiple scales. Large high-level modules correspond to groups of brain regions that share a broad set of functions (e.g. are domain general). Lower-level and smaller modules reflect increasing functional specialization (e.g. may be more domain specific). (C) A final topic that could be explored in future studies is the study of changes in network structure over short timescales. Many cognitive processes unfold over timescales of seconds. In contrast, fMRI resting-state scan sessions can last as long as 30 minutes. This incongruity of timescales makes it difficult to track fast changes in network structure associated with rapid fluctuations in cognitive state. Time-varying or ‘dynamic’ connectivity studies segment time points into windows and separately estimate connectivity for each window, resulting in a time series of dissimilar connectivity matrices.
One particularly intriguing hub that should be targeted in social cognitive network neuroscience is the insula. In social neuroscience research, the insula has been implicated in a variety of social cognitive functions, including several affective states (e.g. disgust and empathy), social decision-making (e.g. Singer et al. , 2009 ) and even loneliness ( Eisenberger and Cole, 2012 ). Network neuroscience has identified the insula as a hub that plays an important role in saliency, task switching, attention and control ( Menon and Uddin, 2010 ). Focusing on the insula as a hub may provide novel insight into its broader role in social cognition.
Many brain systems exhibit known hierarchies and subdivisions, such that they are composed of systems within systems within systems, etc. ( Figure 4B ; Betzel and Bassett, 2018 ). Consider, for instance, the organization of the somatomotor system. At a coarse scale, it can be viewed as a singular system associated with representing sensory information and executing movements. However, its territories can be meaningfully subdivided based on the type of information that a given patch of cortex represents, with distinct subsystems associated differentially with one’s hands, feet, mouth, etc. These subsystems, in turn, can be even further subdivided according to individual digits. Clearly, the coarse grouping of these areas as a singular ‘somatomotor system’ label fails to resolve these fine-scale features. Even at rest there are questions surrounding the correct number of brain systems. For instance, some studies have characterized the brain in terms of a bipartition into large ‘task-positive’ and ‘task-negative’ communities ( Golland et al. , 2008 ), while other studies have focused on finer subdivisions of canonical systems ( Gordon et al. , 2020 ). But how might one access these details using data-driven and network science approaches? Is there a way to resolve different sized communities and modules and, from these different estimates, arrange them into a hierarchy of communities?
Fortunately, the data-driven methods described in the previous section are well-suited for addressing these questions. Both Infomap and modularity maximization include tunable parameters that effectively vary the size and number of detected communities ( Reichardt and Bornholdt, 2006 ). These parameters can be fixed ahead of time to uncover either smaller or larger communities but can also be varied systematically as part of a ‘parameter sweep’ to discover communities across a range of sizes. At the coarsest level, this type of multiscale analysis yields a bipartition of the network into two communities. A parameter sweep will reveal communities of different sizes but will not, unfortunately, determine whether those communities are hierarchically related to one another. However, new methods like multiresolution consensus clustering ( Jeub et al. , 2018 ) use a statistical criterion to arrange a multiscale ensemble of communities into a coherent hierarchy of communities within communities within communities.
Together, these two approaches offer a framework for flexibly examining brain network modules at different scales. Not only does this allow a user to carry out an analysis at one scale or another, but the hierarchy itself can be characterized in the form of different summary statistics, e.g. number of levels, which may vary with cognitive state or clinical condition. This approach may be an interesting complement or alternative to multivariate pattern analyses, which have been widely used in social neuroscience research in recent years (e.g. Weaverdyck et al. , 2020 ). That is, rather than focusing on patterns of activations within specific regions, this approach would allow researchers to explore patterns of connectivity within specific modules.
Functional and structural connectivity represent static network maps of the brain. That is, their connections represent interaction weights between pairs of brain regions either at a specific moment in time or averaged over a longer period. However, brain networks are constantly in flux. Functional connections fluctuate over timescales of seconds and minutes ( Hutchison et al. , 2013 ), possibly reflecting instantaneous changes in cognitive state or performing homeostatic function ( Laumann and Snyder, 2021 ). Similarly, anatomical connections wax and wane over longer timescales with learning, development and aging. Clearly, then, the view of networks as static and temporally invariant objects cannot capture this rich temporal variation. Social neuroscience research has recently embraced a similar viewpoint, integrating techniques such as hyperscanning to measure neural synchrony between two individuals during social interactions ( Misaki et al. , 2021 ).
To better characterize how a network changes over time, a growing number of studies have begun modeling time-varying or dynamic networks, usually in the context of functional connectivity ( Lurie et al. , 2020 ). Estimating time-varying networks is usually carried out using a sliding-window analysis, in which a functional network is estimated using a small subset of time points (those that fall within a temporally contiguous window of fixed length; Shakil et al. , 2016 ; Hindriks et al. , 2016 ; Leonardi and Van De Ville, 2015 ; see Figure 4C ). The window is then advanced by some number of frames, and a new network is generated. This procedure is repeated until the window can be advanced no further, yielding a time series of networks, each corresponding to a different window in time. These networks can be analyzed to track time-varying changes in individual connections or even network properties, like modularity ( Betzel et al. , 2016 ; Fukushima et al. , 2018 ), distribution of hubs and the segregation/integration of brain systems ( Shine et al. , 2016 ).
Time-varying networks can be treated like static networks and analyzed independently of one another. However, they can also be analyzed collectively as part of a multilayer network ( Vaiana and Muldoon, 2020 ). This allows researchers to take advantage of multilayer network analyses tools, including analogs of community detection methods, like modularity maximization ( Mucha et al. , 2010 ). When applied to a multilayer network, this approach yields temporally resolved estimates of communities, allowing users to trivially track changes in community assignments and estimate the network measure of ‘flexibility’—how frequently a node changes its community assignment from one time point to the next ( Bassett et al. , 2011 , 2013 ). In previous studies, flexibility has been linked with learning rate ( Bassett et al. , 2011 ), affective state ( Betzel et al. , 2017 ) and clinical status ( Braun et al. , 2016 ), among others, suggesting that it serves as a powerful marker of behavior.
Time-varying network analysis, however, is not without limitations. Sliding-window analyses require that the user specify the window duration and the amount of overlap between successive windows. Care must be taken in selecting these parameters; short windows can exhibit aliasing effects, and overlap between windows means that the resulting networks are no long independent from one another, which can have implications for their subsequent analysis. To circumvent these issues, several studies have developed ‘point-wise’ estimates of functional connectivity, thus obviating the need for a sliding window while still generating temporally resolved estimates of functional connectivity ( Liu and Duyn, 2013 ; Shine et al. , 2015 ; Esfahlani et al. , 2020 ). These newer methods are relatively untested, but in principle allow users to address some of the issues associated with sliding-window analyses.
In this review, we have provided an overview of the field of network neuroscience with the goal of demonstrating how a social cognitive network neuroscience approach may advance our understanding of the social brain. In addition to providing more comprehensive insights into how the brain gives rise to social behavior, another potential contribution of social cognitive network neuroscience is that it may help address recent critiques arguing that social neuroscience research is too domain specific and overly simplifies our understanding of how the brain gives rise to social behavior ( Barrett and Satpute, 2013 ; Spunt and Adolphs, 2017 ; Ramsey and Ward, 2020 ). These critiques build on prior work highlighting the overlap between seemingly unique cognitive processes (e.g. working memory and intelligence), noting, for instance, that working memory accounts for 40% of the variance in global fluid intelligence ( Fukuda et al. , 2010 ). Extending these observations to the field of social neuroscience, the critiques argue against the notion of a ‘social brain’, suggesting that social and non-social cognitive processes are likely largely overlapping (e.g. Ramsey and Ward, 2020 ). However, an important caveat to these critiques is that although specific brain regions may share social and non-social functions (e.g. Spunt and Adolphs, 2017 ; Ramsey and Ward, 2020 ), the manner in which brain regions communicate information may differ for social and non-social information. Thus, a potential contribution of social cognitive network neuroscience could be to determine whether the manner in which brain systems communicate information differs for social vs non-social information.
Finally, a social cognitive network neuroscience approach has several key benefits. First, it could provide novel insights into how, if at all, brain regions work together to give rise to social behavior. Second, it provides potential resources by which to minimize concerns about power and sample sizes in neuroscience research (e.g. Button et al. , 2013 ; David et al. , 2013 ; Szucs and Ioannidis, 2017 ; Clayson et al. , 2019 ). Specifically, large, publicly available datasets (e.g. the Human Connectome Project; Van Essen et al. , 2013 ) contain resting-state and task-based neuroimaging data from more than 1000 participants, as well as extensive behavioral measures. Large datasets provide opportunities to conceptually replicate findings (e.g. across different subsamples of the dataset; e.g. Bossier et al. , 2020 ), as well as ease for replicability by other researchers, given the established infrastructure for accessing these data. Finally, it could allow us to determine whether a social cognitive network neuroscience approach potentially accounts for unique, or even more, variance in behavior than traditional social neuroscience approaches.

Volume 71, 2020, review article, implicit social cognition.
In the last 20 years, research on implicit social cognition has established that social judgments and behavior are guided by attitudes and stereotypes of which the actor may lack awareness. Research using the methods of implicit social cognition has produced the concept of implicit bias, which has generated wide attention not only in social, clinical, and developmental psychology, but also in disciplines outside of psychology, including business, law, criminal justice, medicine, education, and political science. Although this rapidly growing body of research offers prospects of useful societal applications, the theory needed to confidently guide those applications remains insufficiently developed. This article describes the methods that have been developed, the findings that have been obtained, and the theoretical questions that remain to be answered.

Although a great deal of research has focused on the study of the embodiment of cognition, only recently has the association between the embodiment of cognition and social cognition been acknowledged. Current behavioural and neuroscientific research in cognitive psychology has started to provide empirical evidence, demonstrating the clear link between embodied cognition and cognitive processes dependent on social situations (see Leung et al. 2011 ). That is, sensorimotor experience with the environment can be shown to shape the acquisition and use of knowledge where this environment is embedded in social situations. Hence, cognition is both embodied and social and is referred to as embodied social cognition (EmSoCo). The five empirical articles composing this special section provide some examples of the cutting edge research being carried out in relation to EmSoCo.
As gestures are kinesic components essential to communication (see Cevasco and Marmolejo-Ramos 2013 ), their role in cognition is, therefore, straightforward. Parzuchowski et al. demonstrate that gestures of honesty, e.g. putting a hand on one’s heart, can influence the judgment of others and one’s actions. This supports the idea that abstract concepts are associated with concrete actions and that non-verbal behaviour serves to convey social signals (see also Tagai et al. 2013 ).
That bodily actions portray and communicate social clues, requires also that emotional correlates be appraised. As shown by Stins et al., body sway is influenced by emotionally valenced facial expressions only when an explicit emotional assessment is required; when emotional assessment is irrelevant the effect vanishes. This finding demonstrates that people tend to approach positive and avoid negative situations (see Eerland et al. 2012 ), but adds the cautionary note that such affect only manifests when an explicit emotion is task relevant.
Marmolejo-Ramos et al. have also demonstrated that only when explicit evaluation of the emotionality of stimuli is required, does an association between emotions and concrete concepts emerge. Specifically, these researchers found that emotion concepts can be mapped on vertical spatial locations such that positive concepts are mapped onto upper locations and negative concepts onto lower locations. Although current research has already demonstrated such an association (e.g. Ansorge and Bohner 2013 ), Marmolejo-Ramos et al. extend those results by showing that the effect also holds for linguistic units larger than words, but only when the emotional evaluation is task relevant.
Abstract concepts, e.g. happiness and honesty, can be understood as being mediated by knowledge of concrete entities that can be linked to the abstract referents by conceptual metaphors or metaphoric mapping (see Landau et al. 2010 ). Metaphoric mapping occurs when, for instance, emotions are mapped onto spatial locations (as described above). But less is known about how other abstract concepts, such as time, are mapped onto space. Xue et al. use event-related potentials from Chinese–English bilinguals to demonstrate that sensorimotor systems activate during the processing of temporal markers embedded in sentences presented in these two languages. Although the authors refer to embodied theories of cognition, they present interesting ideas concerning how metaphoric mappings can explain the results that were found.
Behavioural and neuropsychological evidence indicates that language is grounded in the brain’s motor system (see current evidence by Cardona et al. 2014 ). Although most studies in the embodiment framework have used emotion, action and abstract words, very few studies have focused on concepts that refer to schematic representations of embodied experiences. Prieto Velasco and Tercedor Sánchez investigate how concepts referring to image schemas underlie verbal and visual representations of the human body in medical texts. The authors focus particularly on the concept of ‘pain’. Their work provides insights as to how the concept of ‘pain’ is verbally and graphically represented from a medical standpoint. Their findings are in line with current research in cognitive linguistics suggesting that conceptual knowledge, via words and concepts, is closely linked to perceptual properties (see Milin and Zdravković 2013 ).
Embodied cognition has evolved from the biological notion of autopoiesis (see Maturana 2002 ) to the psychological notion of embodiment which is now enriched through its application in accounting for social cognition. Such evolution from biological to psychological notions is evidenced by recent research demonstrating that from early developmental stages, humans display bodily interactions that can be seen as precursors of social skills (see interesting work by Castiello et al. 2010 ). Thus, EmSoCo is a new field of research that extends the broad field of cognitive science. It is expected that future work will not only address new and compelling questions but will also develop new methodologies to help answer these questions. We hope the articles presented in the current special section will provide novel insights on the ways in which social processes reflect the embodiment of cognition. While EmSoCo is still in its infancy, the present studies form a basis for future studies that will either corroborate, extend or even refute the present findings.

Social psychology is a dynamic and multidisciplinary field that delves into the intricate interplay between individuals and their social environments. It seeks to unravel the mysteries of human behavior by exploring how our thoughts, feelings, and actions are shaped by the presence and influence of others. In this introduction, we will define social psychology, emphasize its profound significance, and provide an overview of the diverse range of topics it encompasses. Furthermore, we will present a thesis statement that underscores the paramount importance of comprehending social psychology topics for fostering a deeper understanding of human nature and facilitating positive social change.
Social psychology can be defined as the scientific study of how people’s thoughts, feelings, and behaviors are influenced by the actual, imagined, or implied presence of others. It scrutinizes the intricate web of social interactions, exploring how individuals perceive themselves and others, form attitudes, make decisions, and navigate the complexities of human relationships. At its core, social psychology seeks to unravel the underlying mechanisms that govern our social world, shedding light on the often subtle and nuanced factors that drive human behavior.
The significance of social psychology lies in its ability to provide profound insights into the fundamental aspects of human existence. By examining the ways in which individuals are influenced by their social surroundings, it offers a lens through which we can comprehend societal phenomena, from prejudice and discrimination to cooperation and altruism. Social psychology equips us with the tools to decipher the mysteries of interpersonal dynamics, group behavior, and the intricacies of communication. As we explore the diverse topics within this field, we gain a deeper understanding of the human experience and the profound impact of social influences on our lives.
Social psychology is a vast and multifaceted discipline, encompassing an array of topics that illuminate the complexities of human behavior. These topics span the breadth of human interactions, attitudes, and group dynamics, providing valuable insights into the intricacies of our social world. Some of the key areas of focus within social psychology include:
As we navigate the rich tapestry of social psychology topics, we gain valuable insights into the intricate mechanisms that govern our social interactions. These insights not only enhance our comprehension of human behavior but also empower us to address pressing societal challenges, foster positive relationships, and promote greater social harmony.
In an increasingly interconnected world, a comprehensive understanding of social psychology topics is indispensable for unraveling the mysteries of human behavior, promoting empathy and tolerance, and fostering positive social change. By delving into the depths of social psychology, we equip ourselves with the knowledge and insights necessary to navigate the complexities of our social world, challenge ingrained prejudices, and build more compassionate and inclusive societies. As we embark on this exploration of social psychology topics, we will uncover the profound ways in which our thoughts, feelings, and actions are intertwined with the social tapestry that surrounds us, ultimately enhancing our capacity for empathy and transforming the world we inhabit.
This list of social psychology topics performs two functions. One, the headings alone describe, at a broad level, the kinds of topics covered in the field of social psychology. Looking at the overarching categories, one can see that social psychology studies cognition (thought) and action, helpful and hurtful behaviors, emotions and decisions, culture and evolution, the self and social relationships, as well as health and problematic behaviors. That’s quite a range of topics! The second purpose of the list of social psychology research topics is related to the first in that it helps readers who are already interested in a topic find new topics that may be of interest. In this way, the list provides links among topics.
Social psychology, as a scientific discipline, is dedicated to the exploration of how individuals think about, influence, and interact with one another. In this pursuit, social psychologists delve into various dimensions of human behavior and cognition. They scrutinize the intricacies of social thinking to unravel how we perceive ourselves and those around us. Their examination of social influence delves into the subtle forces at play in conformity, persuasion, and group dynamics. Additionally, social psychologists investigate the complex realm of social relations, seeking to understand the origins of both animosity and empathy among individuals.
Positioned at the intersection of personality psychology and sociology, social psychology occupies a unique niche. To draw a metaphor, while personality psychologists focus on the attributes of individual “boats,” and sociologists navigate the broader “ocean,” social psychologists are primarily concerned with comprehending how these “boats” maneuver within their environment. They investigate the impact of situational factors and social forces on individual behavior and cognition. When an individual, symbolized as a “boat,” encounters a particular environment, analogous to an “ocean,” social psychologists endeavor to discern how external factors, akin to winds and currents, shape their actions and decisions.
While social psychology shares some common inquiries with sociology, it leans toward answers that illuminate the roles of individual actors and their perceptions within social contexts. Rather than concentrating solely on group-level phenomena like poverty or family cohesion, social psychology hones in on the intricacies of individual responses to social situations. Although distinct from personality psychology, which primarily concerns itself with individual differences, social psychology does consider how such differences interact with situational factors. For instance, it might explore how a person with high self-esteem reacts to a threat in their relationship by developing a stronger affinity for their partner.
The practical applications of social psychological research are wide-ranging and have found utility in numerous real-world domains. Researchers have harnessed social psychology to gain insights into health behaviors, such as smoking and condom use, resulting in valuable advancements. For instance, they have played a pivotal role in implementing graphic warnings, like decayed teeth and lungs, on cigarette packaging in Canada to dissuade smoking. In the realm of political psychology, scholars have examined models of persuasion and attitude formation, contributing to our understanding of political behavior. Furthermore, organizational psychologists have applied social psychological theories concerning group dynamics, job satisfaction, and workplace engagement to enhance the functioning of work environments.
The legal arena has also seen the extensive application of social psychological research. In the domain of law, social psychology has exposed the fallibility of eyewitness identification, a crucial element of legal evidence. This research has unveiled the challenges individuals face in accurately identifying those they have witnessed, even after a prolonged observation. Consequently, efforts have been made to refine identification lineup procedures to minimize false positives. For instance, witnesses are now informed that the suspect may or may not be present in the lineup, reducing the likelihood of misidentifications.
Moreover, social psychologists have actively participated in contentious debates surrounding the accuracy of “recovered memories”—recollections of past trauma that individuals believe they have rediscovered later in life. While some of these cases may indeed be genuine, research has demonstrated that false memories can be implanted in individuals. This underscores the need for rigorous scrutiny when evaluating the validity of such memories and highlights the pivotal role of social psychology in shaping the discourse on this topic.
The advent of the digital age has ushered in a transformative era in which technology and social media have become integral aspects of our daily lives. This paradigm shift has not only redefined how we communicate and connect but has also had a profound impact on the field of social psychology. In this discussion, we will explore the multifaceted implications of the digital age on social psychology, encompassing online behavior, identity, self-presentation, the role of social media in information dissemination and social movements, and the ethical considerations that underpin research and interventions in this rapidly evolving landscape.
Online Behavior, Identity, and Self-Presentation
The digital age has given rise to new platforms and mediums through which individuals engage in online behavior. Social networking sites, virtual communities, and online forums have become virtual arenas for social interaction, where individuals communicate, form relationships, and express themselves. Within this context, social psychology examines how online behavior mirrors or deviates from offline behavior, exploring concepts such as online disinhibition, digital self-presentation, and the influence of anonymity.
The creation of online identities, often distinct from one’s offline persona, poses intriguing questions about the construction of self in the digital realm. Social psychologists investigate the factors that influence the portrayal of self online, from the selection of profile pictures to the crafting of digital narratives. Additionally, the digital age has given rise to novel aspects of self-presentation, including the cultivation of curated online personas that may not align with an individual’s authentic self.
The Role of Social Media in Information Dissemination and Social Movements
Social media platforms have revolutionized the way information is disseminated, shared, and consumed. These platforms serve as powerful amplifiers of information, enabling the rapid spread of news, opinions, and ideas. Social psychology explores the dynamics of information flow on social media, examining how content goes viral, the role of algorithms in shaping content exposure, and the formation of online echo chambers where individuals are exposed to information congruent with their existing beliefs.
Furthermore, the digital age has witnessed the emergence of social media as a catalyst for social movements and activism. Movements like #BlackLivesMatter and #MeToo have harnessed the power of social media to mobilize support, raise awareness, and effect social change. Social psychologists investigate the psychological processes underlying online activism, including the role of moral outrage, collective identity, and social support in shaping participation in digital social movements.
Ethical Considerations in Online Research and Interventions
The digital landscape presents unique ethical challenges for researchers and practitioners in social psychology. Online research methodologies, such as studying online communities or analyzing social media data, raise questions about informed consent, privacy, and data security. Researchers must grapple with issues related to the use of publicly available online information versus intrusive data collection.
Moreover, ethical considerations extend to the realm of online interventions and behavior change efforts. The use of persuasive techniques, such as nudges and digital interventions, raises questions about the manipulation of online behavior and the potential for unintended consequences. Social psychologists are tasked with navigating the ethical boundaries of online research and interventions, ensuring that their work respects the autonomy and well-being of individuals in the digital space.
In conclusion, the digital age has ushered in a new frontier for social psychology, one in which the study of online behavior, identity, and social media dynamics is of paramount importance. As technology continues to evolve, social psychologists must grapple with the ethical complexities of this digital landscape while unraveling the intricate ways in which technology and social media shape our perceptions, interactions, and understanding of the social world.
In the realm of social psychology, we have embarked on a captivating journey through the intricate landscape of human behavior and social interactions. Our exploration has unveiled a diverse array of topics, each offering valuable insights into the complex web of influences that shape our thoughts, feelings, and actions. As we conclude our discussion, let us recap the key social psychology topics we have encountered and emphasize the profound significance of this interdisciplinary field. Furthermore, we issue a resounding call to action for the ongoing pursuit of research and understanding of social behavior.
Recap of Key Social Psychology Topics and Their Significance
Throughout our exploration, we have encountered a rich tapestry of social psychology topics, each shedding light on a different facet of human nature and social dynamics. We have delved into the formation and change of attitudes, grappled with the complexities of social influence and conformity, confronted the challenges of prejudice and discrimination, and examined the intricate dynamics of groups and teams. Our journey has taken us through the realms of social cognition and perception, interpersonal relationships, aggression, prosocial behavior, and the transformative impact of technology on social behavior.
These topics are not merely academic pursuits but hold profound significance in our lives and societies. They offer us the tools to comprehend the mechanisms behind our behaviors, beliefs, and interactions with others. They equip us with the knowledge to challenge stereotypes, biases, and discriminatory practices, fostering greater empathy, tolerance, and inclusivity. Moreover, they empower us to navigate the complexities of group dynamics, relationships, and digital interactions in an ever-evolving world.
Emphasis on the Interdisciplinary Nature of Social Psychology
Social psychology is a field that bridges disciplines, drawing insights from psychology, sociology, anthropology, and neuroscience, among others. It underscores the interconnectedness of these disciplines and highlights the fundamental role of social factors in shaping individual and collective behavior. As we have seen, social psychology thrives on collaboration and the integration of diverse perspectives to provide a holistic understanding of human behavior in its social context.
Call to Action for Continued Research and Understanding of Social Behavior
Our exploration of social psychology has only scratched the surface of this vast and ever-evolving field. It is imperative that we recognize the ongoing relevance and necessity of research in this domain. The challenges and opportunities presented by our interconnected world demand a deeper understanding of social behavior, both online and offline. We must continue to explore the intricacies of attitudes, influence, prejudice, relationships, and the impact of technology with unwavering curiosity and dedication.
As individuals, scholars, and global citizens, we are called to action. We must engage in ongoing research that deepens our understanding of the human experience and promotes positive social change. We must challenge stereotypes and biases, foster empathy, and build inclusive communities. In an era of rapid technological advancement and global interconnectedness, the lessons of social psychology are more relevant than ever.
In conclusion, social psychology is not merely an academic pursuit but a lens through which we can better comprehend ourselves and the world around us. It offers the potential for transformative change, a bridge between disciplines, and a roadmap to a more compassionate and harmonious society. Let us heed this call to action, embrace the interdisciplinary nature of social psychology, and continue our quest for a deeper understanding of social behavior—one that brings us closer to a more inclusive, empathetic, and interconnected world.
The Way We Think About Others
Social cognition refers to the different psychological processes that influence how people process, interpret, and respond to social signals. These processes allow people to understand social behavior and respond in ways that are appropriate and beneficial.
Social cognition is a sub-topic of social psychology that focuses on how people process, store, and apply information about others and social situations. It focuses on the role that cognitive processes play in our social interactions. How we think about others plays a major role in how we think, feel, and interact with the world around us.
This article explores the processes involved in social cognition and how this ability forms. It also explores how psychologists study the processes involved in social cognition.
Social cognition encompasses a range of processes. Some common factors that many experts have identified as being important include:
Another important topic in social cognition is the concept of social schemas. Social schemas refer to people's mental representations of social patterns and norms. These representations can include information about societal roles and the expectations of different individuals within a group.
Social cognition is not simply a topic within social psychology —it is an approach to studying any subject with social psychology. Using a social-cognitive perspective, researchers can study a wide range of topics, including:
Imagine that you are getting ready to go on a blind date. Not only do you worry about the impression and signals that you are sending to the other person, but you are also concerned with interpreting the signals given by your date.
Questions you might ask include:
This is just one example of how social cognition influences a single social interaction, but you can probably think of many more examples from your daily life. We spend a considerable portion of every day interacting with others, which is why this branch of psychology formed to help understand how we feel, think, and behave in social situations.
Social cognition develops in childhood and adolescence. As children grow, they become more aware not only of their own feelings, thoughts, and motives but also of the emotions and mental states of others.
Children become more adept at understanding how others feel, learning how to respond in social situations, engaging in prosocial behaviors , and taking the perspective of others.
While many different theories look at how social cognition develops, one of the most popular focuses on the work of the psychologist Jean Piaget. According to Piaget, a child's cognitive development goes through several stages .
More recently, research has provided evidence that children develop the ability to think about other people's perspectives at an earlier age than Piaget believed. Even young preschoolers exhibit some ability to think about how other people might view a situation.
One of the most important developments in the early emergence of social cognition is the growth of a theory of mind. A theory of mind refers to a person's ability to understand and think about the mental states of other people.
It is the emergence of a theory of mind that is critical to being able to consider the thoughts, motives, desires, needs, feelings, and experiences that other people may have. Being able to think about how these mental states can influence how people act is critical to forming social impressions and explaining how and why people do the things that they do.
Certain mental health conditions are characterized by disruptions in social cognition. Examples include:
Social psychologists have also found that there are often important cultural differences in social cognition. When looking at a social situation, any two people may have wildly different interpretations. Each person brings a unique background of experiences, knowledge, social influences, feelings, and cultural variations.
Collective cultural influences can also affect how people interpret social situations. The same social behavior in one cultural setting might have a very different meaning and interpretation if it were to occur or be observed in another culture.
As people interpret behavior, extract meaning from the interaction, and then act based upon their beliefs about the situation, they are then further reinforcing and reproducing the cultural norms that influence their social cognitions.
Research into social cognition is ongoing. But there are also challenges to some established theories.
So what are some of the different questions related to social cognition that researchers are interested in understanding? Our perceptions of others play such an important role in how we forge relationships, how we interact with others, how we treat others, and how others treat us.
Some of the topics that psychologists are interested in when it comes to social cognition include:
One criticism of some of the research on social cognition suggests that it is too focused on individual behavior. Because the topic is so social, some suggest that many information-processing models traditionally used to understand the cognitive processes behind social cognition are too limited.
Focusing on the collective and interactive aspects of human thought may provide a better understanding of how people think about and understand social behavior.
Other critics have noted that the field often focuses too heavily on the reasons for a behavior and not on the underlying causes.
Social cognition is the cognitive processes that influence social behavior. Learning more about this perspective offers insights into how other people shape our behaviors and choices. It also plays a role in understanding how individual cognitions affect how we perceive and respond to others.

Human reasoning on social interactions in ecological contexts: insights from the theory of mind brain circuits.
Introduction: The relationship between neural social cognition patterns and performance on social cognition tasks in daily life is a topic of debate, with key consideration given to the extent to which theory of mind (ToM) brain circuits share properties reflecting everyday social functioning. To test the efficacy of ecological stimuli in eliciting brain activation within the ToM brain circuits, we adapted the Edinburgh Social Cognition test social scenarios, consisting of dynamic ecological contextually embedded social stimuli, to a fMRI paradigm.
Methods: Forty-two adults (21 men, mean age ± SD = 34.19 years ±12.57) were enrolled and underwent an fMRI assessment which consisted of a ToM task using the Edinburgh Social Cognition test scenarios. We used the same stimuli to prompt implicit ( movie viewing ) and explicit ( silent and two-choice answers ) reasoning on cognitive and affective mental states. The fMRI analysis was based on the classical random effect analysis. Group inferences were complemented with supplemental analyses using overlap maps to assess inter-subject variability.
Results: We found that explicit mentalizing reasoning yielded wide neural activations when two-choice answers were used. We also observed that the nature of ToM reasoning, that is, affective or cognitive, played a significant role in activating different neural circuits.
Discussion: The ESCoT stimuli were particularly effective in evoking ToM core neural underpinnings and elicited executive frontal loops. Future work may employ the task in a clinical setting to investigate ToM network reorganization and plasticity.
While navigating in the social world, individuals’ proficiency in interpreting and reacting to social cues is indispensable to allow them to behave appropriately and participate in successful social interactions ( Dziobek et al., 2006 ; Frith, 2008 ; Adolphs, 2009 ; Henry et al., 2015 ; Love et al., 2015 ; Baez et al., 2017 ). This social proficiency relies on a complex set of processes known as social cognition abilities, which are acquired in infancy and continuously developed during the lifespan. Among these abilities, theory of mind (ToM) ( Adolphs, 2009 ; Henry et al., 2013 ; Happé et al., 2017 ), the capacity to infer and respond to others’ mental states driving their behavior, assuring the prediction and adequate response to others’ social conduct ( Baglio and Marchetti, 2016 ), is considered a key multidimensional social cognitive process, constituted by two main components, namely, affective and cognitive ToM. Specifically, reasoning on emotions refers to affective ToM, and reasoning on thoughts and beliefs refers to the cognitive ToM component.
Existing tests of ToM, however, have been criticized for their unnaturalistic and artificial nature, and therefore, the ecological validity of ToM measures to reflect social processing in daily life has gained attention ( Mathersul et al., 2013 ). The adoption of ecological stimuli resembling the richness and complexity of daily life scenarios may reliably stimulate everyday social processing ( Redcay and Moraczewski, 2020 ). In particular, movies depicting social interactions, rather than static images or written text, may be capable of eliciting social cognition operations in daily life. Real-world social cognitive processes rely on the online processing of dynamic multimodal, contextually embedded, temporally extended social events ( Redcay and Moraczewski, 2020 {Msika, 2024, Dynamic and/or multimodal assessments for social cognition in neuropsychology: Results from a systematic literature review}). Such processes are scarcely resembled by static and simplistic stimuli.
Some movie-based social cognition tests exist in the literature including the Movie for the Assessment of Social Cognition (MASC; Dziobek et al., 2006 ), the Awareness of Social Inference Test (TASIT; McDonald et al., 2003 ), the Awkward Moments Test ( Heavey et al., 2000 ), and the Empathic Accuracy Paradigm ( Roeyers et al., 2001 ). However, these tests are not without their limitations such as lacking important contextual information, offering exaggerated interactions, or being dubbed from other languages. Interestingly, virtual reality is starting to be adopted in neuropsychological assessment ( Krohn et al., 2020 ), and the Virtual Assessment of Mentalizing Abilities (VAMA) has been proposed as an ecologically valid tool allowing evaluation of mental state reasoning in an interactive virtual environment ( Canty et al., 2017 ). However, virtual reality systems may be not easily accessible due to the high cost related to technologies. In addition, interindividual differences in computer experience and in adaptation to the virtual environment may affect performance ( Parsey and Schmitter-Edgecombe, 2013 ).
The Edinburgh Social Cognition test (ESCoT; Baksh et al., 2018 , 2020 , 2021 ; Poveda et al., 2022 ) is a measure of ToM and social norm understanding, and it has been implemented and validated in the United Kingdom and recently adapted for the Italian culture ( Isernia et al., 2022a ). The ESCoT assesses social abilities through everyday scenarios presented by dynamic cartoons showing a social interaction in which a character adheres to or violates a social rule in the face of a contextual request. The ESCoT provides several advantages: each cartoon measures both affective and cognitive ToM separately; its stimuli resemble the complexity of everyday social interactions; and it enables a multidimensional assessment of ToM. In fact, both social rules and contextual events are crucial to understand and infer the characters’ mental states during the social interactions in the ESCoT scenarios. Each movie depicts an expected or unexpected behavior of one character toward another based on social norms and contextual events (e.g., helping an older woman when her shopping bag breaks; not giving a pregnant woman a seat on the bus). The ESCoT scenarios show ten disparate social situations: helping the elderly, disobeying parking regulations, being considerate on the bus, cleaning up after own pet, assisting a neighbor, smoking in a prohibited area, talking in the cinema, serving a customer, skipping a bus queue, and assisting a stranger. By reasoning about the mental states of characters in those social scenarios, people are prompted to contextually embed social inferences, which are tightly dependent on how social capabilities adapt to the complexity of real-life situations.
Previous research has revealed that the ESCoT is not influenced by intellectual abilities or executive functions in healthy participants ( Baksh et al., 2018 ; Isernia et al., 2022a ), distinguishing itself from other social cognition tests ( Charlton et al., 2009 ; Aboulafia-Brakha et al., 2011 ). In addition, the ESCoT has shown good diagnostic validity in discriminating between autistic and non-autistic participants ( Baksh et al., 2021 ), individuals with and without acquired brain injuries ( Poveda et al., 2022 ), and people with dementia with and without behavior change, unlike established tests of social cognition ( Baksh et al., 2023 ). Given these advantages of the ESCoT, its stimuli may be a suitable way to study the neural mechanisms of mentalizing in real-life scenarios, where contextual events and social rule understanding are involved in the processing of social information.
The ToM neural-network model of Abu-Akel and Shamay-Tsoory (2011) introduces a highly complex map of interconnected neuroanatomical hubs devoted to mental state representation, attribution, and application. Based on this paradigm, mental state representations involve the temporoparietal junction (TPJ), the precuneus, the posterior cingulate cortex (PCC), and superior temporal sulcus (STS), that is, the core ToM network. In this model, partially dissociated mechanisms underlying cognitive and affective ToM have been identified in the limbic and paralimbic areas (the limbic–paralimbic ToM network): the amygdala and the ventral portion of the anterior cingulate cortex, temporal pole, and striatum are especially devoted to affective mental state understanding (affective ToM), whereas the dorsal part of the anterior cingulate cortex, temporal pole, and striatum are involved in cognitive mental state comprehension (cognitive ToM). The dissociation between affective and cognitive ToM neural hubs also involves frontal portions: the dorsomedial and dorsolateral prefrontal cortex (cognitive ToM), the ventromedial prefrontal cortex, and inferolateral and orbitofrontal cortex (affective ToM). In particular, the communication between the limbic–paralimbic ToM areas and key frontal regions enables behavior predictions based on affective and cognitive mental states.
Ecologically valid stimuli in fMRI may reveal neural regions engaged while mentalizing in a naturalistic context ( Wolf et al., 2010 ; Redcay and Moraczewski, 2020 ; Hildebrandt et al., 2021 ). Jacoby et al. (2016) demonstrated that a non-verbal animated movie with segments eliciting emotions and beliefs was able to efficiently localize ToM functional networks, such as the bilateral STS, TPJ, precuneus, ventromedial prefrontal and dorsomedial prefrontal cortices. In addition, Pantelis et al. (2015) administered movies from a TV series in fMRI to healthy participants and autistic people to identify neural areas involved in the perception of socially awkward moments. They found activation in the right TPJ, which was selectively engaged in healthy controls and decreased in autistic people. Wolf et al. (2010) explored the neural mechanisms for both implicit and explicit mental state reasoning by adapting the MASC test into an fMRI task; they reported correspondence with typical mentalizing network areas recruited in implicit ToM reasoning during the passive movie viewing, such as the left TPJ, left precuneus, bilateral occipitotemporal cortex, and left precentral gyrus, and explicit ToM reasoning, left TPJ, left precuneus, left dorsomedial prefrontal cortex, left superior prefrontal gyrus, bilateral STS, bilateral temporal pole, and bilateral inferior frontal gyrus.
We believe that the ESCoT scenarios could be used as fMRI ecological stimuli able to elicit ToM reasoning neural patterns and differential networks for ToM affective and cognitive components.
The aim of the current study was to test the capacity of dynamic, contextually embedded, social scenarios, such as the ESCoT stimuli, in eliciting neural circuits involved in human mentalizing, and, then, propose the ESCoT scenarios as an effective and comprehensive fMRI paradigm for the assessment of cognitive and affective ToM networks.
We adapted the ESCoT into an fMRI task and administered it to a group of healthy adults. Our approach focused on verifying the engagement of ToM neural networks considering a well-recognized ToM neural-network model ( Abu-Akel and Shamay-Tsoory, 2011 ). Specifically, when investigating the overall mentalizing reasoning compared to physical inference (control condition), we expect to find a prevalent involvement of the core ToM network, according to Wolf et al. (2010) . Moreover, when the two ToM components are separately prompted, we expect to observe an extended neural pattern also involving specific cognitive and affective ToM limbic–paralimbic and executive frontal areas as detailed in the ToM neural-network model.
This is a prospective cross-sectional study conducted at the IRCCS Don Gnocchi Foundation of Milan between May 2022 and April 2023. The study protocol was approved by the “Fondazione Don Gnocchi-Milan” Ethics Committee: protocol number 08_23/02/2022. The research conformed to the ethical principles of the Helsinki Declaration revised.
Healthy adults were enrolled in the IRCCS Don Gnocchi Foundation clinic (Milan). They were researchers, volunteers, administrative staff, interns, and students attending the clinic. All participants enrolled agreed to take part in the research without receiving monetary compensation. They received a magnetic resonance report at the end of the study.
Before accepting eligible participants for the study, a brief clinical interview was performed to ensure they complied with the research study’s inclusion/exclusion criteria: (i) age ≥ 18; (ii) absence of neurologic and/or major psychiatric conditions; (iii) absence of pharmacological treatment with antipsychotics, antidepressants, and/or antiepileptic that may interfere with the fMRI acquisition; (iv) absence of non-corrected visual impairment able to impact the fMRI acquisition (i.e., inability to wear contact lenses for myopia); (v) absence of hearing impairment able to impact the behavioral assessment; (vi) absence of MRI contraindications (i.e., pacemaker, metal implants, and crystalline surgery in the last month). All participants read and signed the written informed consent.
We enrolled a total of 42 healthy adults (21 men, mean age ± SD = 34.19 years ±12.57, mean full-time years of education ± SD = 16.27 years ±3.08). Among these, seven participants were excluded from the analyses: one due to a brain lesion and six due to low-quality MRI data due to movement artifacts (head motion above 2 mm/2°).
After recruitment into the research study, participants were involved in an individual session in the clinic to perform: (i) an MRI acquisition lasting approximately 40 min in total and (ii) a neuropsychological assessment lasting approximately 1 h. The MRI examination included brain structural MRI sequences to study brain morphometry and exclude gross brain abnormalities, and the ESCoT fMRI ToM task, preceded by 10 min of familiarization with the task instructions and stimuli outside the MRI scanner (see Section 2.3.2). The neuropsychological assessment comprised a test battery to evaluate both non-social cognitive level and social cognitive abilities (see Section 2.3.3).
2.3.1 fmri tom task implementation.
A new fMRI ToM task was derived from the Edinburgh Social Cognition Test (ESCoT, Baksh et al., 2018 ), originally developed in the United Kingdom ( Baksh et al., 2018 , 2020 , 2021 ; Poveda et al., 2022 ) and then adapted for the Italian language ( Isernia et al., 2022a ), assessing affective and cognitive ToM and social norm understanding with an ecological and multidimensional approach. The test consists of 11 cartoon-style silent animations (30 s each) depicting real-life social interactions. The animations show social interactions complying with or violating social norms in a daily life context (e.g., assisting a stranger, skipping a bus queue, and smoking in a prohibited area). Each animation evaluates separately cognitive and affective components of ToM, and interpersonal and intrapersonal comprehension of social norms (i.e., social knowledge). In its original version, participants are invited to watch animations and then answer open-ended questions about what happened in the videos (animation comprehension), what a character is thinking (cognitive ToM), how a character is feeling (affective ToM), whether a character behaves as other people should behave (interpersonal comprehension of the social norm), and whether the participant would have acted the same as the character (intrapersonal comprehension of the social norm). Each answer is scored from 0 to 3 points, with 3 points indicating an optimal interpretation of the social dynamics, explicitly extracting and integrating relevant social information and contextual factors influencing characters’ behavior. A score of 2 indicates a response that explicitly extracts the relevant social information but does not integrate it into the context related to the interaction or refers to the extraction of low-level social information related to the context. A score of 1 recognizes a non-social information response, even with the mention of contextual requests. A score of 0 indicates an “I do not know” answer. For a detailed description of the scoring procedure, please refer to Isernia et al. (2022a) and Baksh et al. (2018) (see Figure 1 for an example).
Figure 1 . Storyboard of an ESCoT movie (“Helping the elderly”) and the description of the social scenario of the movie.
For the fMRI adaptation, the ESCoT animation stimuli were adapted to have the same duration (23 s), specifically the vignettes have been shortened by cutting only the start or the end frames when the social interaction has not yet occurred/was already concluded. In addition, instructions for both open- (silent) and closed-ended questions were implemented for each animation assessing social cognition. Then, before implementing the definitive version of the task, pilot versions were administered inside the MRI scanner. The first pilot version of the task included both questions on ToM and comprehension of social norms. However, after preliminary analyses reporting inconsistent neural activations related to social norm comprehension among participants, the task was modified to assess only ToM (affective and cognitive components).
In its final version, the ESCoT fMRI task has been implemented in a way that the same stimuli (video clips) were used to investigate neural correlates elicited by ToM reasoning (experimental condition) and physical inference (control condition). To this purpose, the ESCoT fMRI task consisted of two blocks (A–B) modeling two different conditions: the ToM experimental condition (A) and the physical inference (PI) control condition (B). Moreover, in each block, the same stimuli were used to test the neural activations of implicit reasoning , namely, the reasoning spontaneously elicited by the stimulus itself, not resulting from a specific question, and the explicit reasoning , which instead consists of reasoning elicited by questions that purposely direct attention toward mental states or physical elements (see Figure 2 ).
Figure 2 . Overview of the block design of the task-fMRI experiment. The items of the two blocks (namely, Block A—Theory of Mind Experimental Condition, and Block B—Physical Inference Control Condition) are shown, together with the stimuli duration, according to the order of presentation.
Specifically, the ToM experimental block (A) included the following items:
1. Social cognition instructions : written instructions for the movie scene ( “Focus on characters’ interactions” ) lasting on the screen for 4 s;
2. Implicit ToM reasoning : cartoon-style animation movie watching, lasting 23 s;
3. Explicit affective ToM reasoning – Silent answer : silent answer to affective ToM question ( “How is the woman feeling?” ), lasting on the screen for 9.5 s;
4. Explicit affective ToM reasoning – Closed-ended answer : two -choice answer to affective ToM question ( “Is the woman disappointed by the man behavior?” ), lasting on the screen for 3.5 s;
5. Explicit cognitive ToM reasoning – Silent answer : Silent answer to cognitive ToM question ( “What is the woman thinking?” ), lasting on the screen for 9.5 s;
6. Explicit cognitive ToM reasoning – Closed-ended answer : two-choice answer to cognitive ToM question ( “Did the man act as the woman would expect?” ), lasting on the screen for 3.5 s.
The PI control block (B) included the following items:
1. Physical instructions: written instruction for the movie scene (“ Focus on the elements in the scene ”) lasting 4 s;
2. Implicit physical inference: cartoon-style animation movie watching, lasting 23 s;
3. Explicit physical inference – Silent answer: silent answer to PI question (“ What color is the man’s hair? ”), lasting on the screen for 9.5 s;
4. Explicit physical inference – Closed-ended answer: two-choice answer to PI question (“ Is the man’s hair black? ”), lasting on the screen for 3.5 s.
All items presented in each block were interleaved by a white fixation cross on a black background of variable duration (ranging between 2 to 3 s, and 6 s between blocks) (see Figure 2 ).
The fMRI task included a total of 10 animation movies (the remaining animation was used for familiarization of the task outside the MRI scanner), each of which was administered twice: once during the ToM experimental condition and once for the PI control condition, according to a randomized order. The task administration was split into two separate, but sequential runs (5 movies each) during the same scanning session. Both the task sessions lasted approximately 10 min for a total fMRI task duration of 20 min. The closed-ended two-choice answer was recorded using a dedicated device, namely, an Evoke Response Pad System (Resonance Technology Inc.), and consisted of pressing a button with the index or middle finger to indicate positive or negative answers, respectively. The task was implemented and successively administered using E-Prime 3.0 (Psychology software tools) 1 .
The data were acquired on a 3 T Siemens Prisma scanner (Erlangen, Germany) equipped with a 64-channel head/neck coil. The acquisition protocol included the following: (1) a T1-3D magnetization prepared rapid acquisition with gradient-echo (MPRAGE) sequence with a repetition time (TR) = 2,300 ms, echo time (TE) = 3.1 ms, isotropic resolution = 0.8 × 0.8 × 0.8 mm 3 , 224 slices, which was used as an anatomical reference; (2) a sagittal fluid-attenuated inversion recovery (FLAIR) sequence was also acquired TR = 5,000 ms, TE = 394 ms, resolution = 0.8 × 0.8 × 1 mm 3 , acquisition matrix = 288 × 320, 176 slices, to exclude gross brain abnormalities; (3) an accelerated GE sequence with TR = 2000 ms, TE = 30 ms, resolution 3 × 3 × 3 mm 3 , multi-slice acceleration factor = 2, 52 slices, 333 measurements, 2 runs for fMRI.
The ESCoT visual stimuli were delivered using E-Prime 3.0 [Psychology software tools (see Footnote 1)] by means of a NordicNeuroLab system 2 comprising an “in-room viewing device.” Specifically, an MR-compatible display was located at the end of the gantry, and a mirror was placed on the head coil to allow the participant to see the monitor. The stimuli administration was synchronized with the MR acquisition by means of a dedicated device (SyncBox). The participants were trained before entering the MRI scanner and performed a trial mimicking the fMRI experiment structure involving an ESCoT test video.
The neuropsychological test battery included both conventional non-social cognitive measures and social cognition tools.
Non-social cognitive measures comprised the following:
Montreal Cognitive Assessment (MoCA; Conti et al., 2015 ; Santangelo et al., 2015 ) to assess global cognition. The total score ranging from 0 to 30 (greater cognitive level) was adjusted for age and years of education based on the instructions of Santangelo et al. (2015) .
Trail Making Test (TMT; Giovagnoli et al., 1996 ) to evaluate shifting. Performance time was recorded both for TMT parts A and B, and total scores were adjusted for age and years of education according to Giovagnoli et al. (1996) .
Stroop Color-Word Test ( Strauss et al., 2006 ) to assess inhibition. Performance time and errors were registered, and total time and total errors were computed and adjusted for age and years of education according to Caffarra et al. (2002) .
Digit Span Test ( Monaco et al., 2013 ) to assess short-term and working memory. Forward and backward total scores were computed and adjusted for sex, age, and years of education based on the instructions of Monaco et al. (2013) .
Symbol Digit Modality Test (SDMT; Sheridan et al., 2006 ) to evaluate processing speed and attention. The total score was computed and adjusted according to Rao (1990) .
Social cognition measures included the following:
Yoni Task ( Shamay-Tsoory and Aharon-Peretz, 2007 ; Isernia et al., 2022c ) to evaluate cognitive and affective, first-order and second-order ToM with visual cartoon-like stimuli. The 48-item version was administered, and total accuracy and total response time indexes (range 0–1) were computed and adjusted for sex, age, and education according to Isernia et al. (2022c) .
Reading the Mind in the Eyes test (RME, Baron-Cohen et al., 2001 ) to evaluate ToM through photographs of the eye region expressing complex mental states. The total score (range 0–36) was computed and adjusted according to Maddaluno et al. (2022) .
2.4.1 fmri data preprocessing.
The EPI functional data were preprocessed, according to a standard pipeline, using the Statistical Parametric Mapping toolbox (SPM12) 3 running on MATLAB (MathWorks) 4 . The first 10 acquired volumes were considered as ‘dummy scans’ and were discarded to account for magnetization to reach the steady state. The two runs were preprocessed together by setting two different sessions. The first step of the preprocessing involved motion correction and realignment of functional volumes to an average reference volume. The degree of head motion was assessed, and participants with movements exceeding the threshold set at 2 mm/2° were excluded from further analysis. Then, the co-registration with individuals’ anatomical volumes (MPRAGE) was performed. Specifically, the MPRAGE anatomical volumes were preprocessed using the FMRIB Software Library v6.0 (FSL) 5 according to the following steps: bias field correction ( Tustison et al., 2010 ) and brain extraction ( Smith, 2002 ; Jenkinson et al., 2005 ). The individual volumes were successively used as anatomical references for the registration of functional volumes, performed in SPM, at the subject level. The last steps involved segmentation and normalization to the standard MNI template and smoothing (8 mm full width at half-maximum isotropic Gaussian). The preprocessed volumes served as input to the following first-level statistical analyses.
A priori sample size calculation: in accordance with the recommendations reported in Szucs and Ioannidis (2020) , we used G*Power (version 3.1.9.7) to a priori estimate the sample size for the study. A total of 31 participants resulted as necessary to achieve a power equal to 0.85 for one-sample t -test analysis (d = 0.5) and α threshold = 0.05. We considered enrolling an additional 15% of subjects to account for eventual exclusions from fMRI analysis due to low-quality data or due to non-compliance with the MRI scan.
The general linear model (GLM) was used to construct and fit the statistical model on the BOLD response to perform the first-level analysis at the subject level. Every item was modeled as a single event inside each block (ToM “experimental” block and PI “control” block), namely, movie viewing, silent answering, and two-choice question answering, and represented the regressors of interest. The six motion parameters were instead inserted in the model as nuisance regressors. Seven different contrasts were considered comparing the different items between the two conditions (i.e., ToM Experimental condition and PI Control condition), specifically, (1) implicit ToM reasoning vs. implicit PI (movie viewing following “ToM instruction” vs. movie viewing following “PI instruction”), (2) explicit ToM reasoning vs. explicit PI silent answer, (3) explicit ToM reasoning vs. explicit PI closed-ended answer, (4) explicit affective ToM (aToM) reasoning vs. explicit PI silent answer, (5) explicit aToM reasoning vs. explicit PI closed-ended answer, (6) explicit cognitive ToM (cToM) reasoning vs. explicit PI silent answer, and (7) explicit cToM reasoning vs. explicit PI closed-ended answer.
To directly test the selective activation of the affective and cognitive ToM dimension, four additional contrasts, directly testing the differences between ToM components during both silent and closed-ended explicit reasoning, have been computed: (8) explicit aToM reasoning vs. explicit cToM reasoning silent answer, (9) explicit cToM reasoning vs. explicit aToM reasoning silent answer, (10) explicit aToM reasoning vs. explicit cToM reasoning closed-ended answer, and (11) explicit cToM reasoning vs. explicit aToM reasoning closed-ended answer.
Moreover, to complement the classical GLM factorial analysis, subjects’ interindividual variability was performed. Specifically, subject-specific activation maps derived for all the above-mentioned contrasts have been used to compute threshold-dependent overlap maps representing the proportion of subject activation in a given region of interest (ROI) ( Seghier and Price, 2016 ). The ROIs were defined according to an in-house developed atlas-derived inclusive mask previously described in Isernia et al. (2022b) , comprising the cerebral areas relevant to ToM reasoning according to Abu-Akel and Shamay-Tsoory’s model ( Abu-Akel and Shamay-Tsoory, 2011 ). The subject-specific activation maps were derived according to the following thresholds: p unc < 0.001 and cluster size ≥30.
The resulting subject-level contrasts were used to perform second-level group analysis, modeled in the GLM as one-sample t -tests. The statistics were restricted using an in-house developed atlas-derived inclusive mask previously described in Isernia et al. (2022b) , to the cerebral areas relevant to ToM processing according to the Abu-Akel and Shamay-Tsoory’s model ( Abu-Akel and Shamay-Tsoory, 2011 ). In brief, the mask was composed of 11 bilateral non-overlapping ROIs, constituting the four ToM circuits depicted by the model: the ‘ Core ToM Network’ , composed of TPJ, precuneus, and PCC and the anterior division of the STS; the ‘ Limbic–Paralimbic ToM Network’ , composed by anterior cingulate cortex (ACC), TP, dorsal striatum, ventral striatum, and amygdala; the ‘ Cognitive Execution Loop’ , composed by dorsal medial and dorsal lateral PFC; the ‘ Affective Execution Loop’ , composed by the orbitofrontal cortex and ventromedial PFC, and the inferolateral PFC. The functional activation maps were considered statistically significant for p FWE < 0.05 considering the family-wise error (FWE) correction for multiple comparisons to account for false positives. A threshold on cluster size was also set to consider clusters larger than 30 voxels.
Thirty-five participants (18 men, mean age ± SD = 34.23 years ±12.72, mean years of education ± SD = 16.46 years ±2.70) were included in the analyses. Table 1 reports the cognitive and psychosocial characteristics of the participants included in the analyses. Participants showed high performance on all the neuropsychological tests.
Table 1 . Neurocognitive profile of the sample.
The task-fMRI performance for the closed-ended questions, for both the ToM experimental and PI control conditions, is reported in Table 2 . Specifically, the reaction times (RT), namely, the elapsed time between the question presentation and the participants pressing the button, the number of missing answers, and the number of wrong answers were assessed for the affective ToM (aToM), cognitive ToM (cToM), and PI closed-ended questions. All participants correctly answered at least 75% of overall questions with a low rate of missing/wrong answers and average RT below the 3,000-ms time limit.

The results of the fMRI analysis are reported in detail in Table 3 and Figure 1 for the ToM performance vs. PI and separately for affective ToM and cognitive ToM vs. PI in Table 4 and Figure 2 . Specifically, for the first contrast ( implicit ToM reasoning vs. implicit PI ), investigating the implicit ToM reasoning, no significant neural activation was retrieved. For the second contrast ( explicit ToM reasoning vs. explicit PI silent answer ), the functional activations were located in the left TP, both superior and middle (BA 21, 22, 38) ( Figure 3 ). The third contrast ( explicit ToM reasoning vs. explicit PI closed-ended answer ) yielded significant activation in the bilateral temporal cortex, specifically superior and middle temporal gyri (BA 21, 22, 39), and precuneus (BA 7), left temporal pole (BA 38), inferior frontal cortex (pars orbitalis and pars triangularis), and insula ( Figure 3 ). Furthermore, significant clusters were retrieved in the left middle frontal cortex and precentral gyrus.

The significant clusters of activation are reported in red-yellow expressing the t-values according to the reported color bar. ToM, theory of mind; PI, physical inference; L, left; R, right. The significant clusters for each contrast are mapped according to the Abu-Akel and Shamay-Tsoory ToM model depicted on the right [adapted from Isernia et al. (2022b) ].
Explicit ToM reasoning was also investigated separately for the affective (contrasts 4 and 5) and cognitive (contrasts 6 and 7) ToM components through the use of silent open-ended questions and two-choice closed-ended questions.
The fourth contrast ( explicit aToM reasoning vs. explicit silent answer ) did not yield any significant supra-threshold activation, while the fifth contrast ( explicit cToM reasoning vs. explicit PI silent answer ) revealed significant functional activations in the bilateral TP (BA 38), precuneus (BA 7), right superior and middle temporal gyri (BA 21), the left inferior frontal cortex (BA 47), specifically the orbital and triangular pars ( Figure 4 ).
Figure 4 . fMRI GLM results. This figure shows the fMRI results observed for silent and closed-ended answering separately for affective (contrast 5) and cognitive (contrasts 6 and 7) ToM reasoning with respect to the physical inference control condition. The significant clusters of activation are reported in red-yellow expressing the t -values according to the reported color bar. ToM, theory of mind; PI, physical inference; L, left; R, right. The significant clusters for each contrast are mapped according to the Abu-Akel and Shamay-Tsoory ToM model depicted on the right [adapted from Isernia et al. (2022b) ].
As for the sixth contrast ( explicit cToM reasoning vs. explicit PI silent answer ), the activations were confined to the left superior and middle TP (BA 21, 38) ( Figure 4 ), while for the seventh contrast ( explicit cToM reasoning vs. explicit PI closed-ended answer ), activation was elicited in the bilateral precuneus (BA 7), bilateral superior temporal gyrus (BA 39), and left middle temporal gyrus (BA 39) ( Figure 4 ). As for the contrasts used to directly test for differences between the affective and cognitive ToM components, contrast 8 ( explicit aToM reasoning vs. explicit cToM reasoning silent answer ) yielded no significant supra-threshold activation, while contrast 9 ( explicit cToM reasoning vs. explicit aToM reasoning silent answer ) showed neural activation located in the bilateral TPJ (BA 39); contrast 10, namely, explicit aToM reasoning vs. explicit cToM reasoning closed-ended answer , showed significant neural activation in the left superior temporal sulcus, while contrast 11 (explicit cToM reasoning vs. explicit aToM reasoning closed-ended answer ) revealed no supra-threshold clusters. Detailed results and figures are reported in Supplementary Figure S1 .
The ROI-based individual variability analysis revealed low across-subjects consistency with respect to the neural activation elicited by the contrast testing for implicit ToM reasoning. Higher across-subjects consistency was instead observed for the other contrasts specifically in the left TP, left STS, left dorsolateral PFC, bilateral TPJ, and precunei.
The overlap maps and relative histograms are reported in Supplementary Figures S2–S8 .
We aimed to explore the brain mechanisms involved in ToM reasoning during everyday social interactions. We adapted the Italian version of the ESCoT into an fMRI task to understand the engagement of ToM neural networks in healthy adults. We hypothesized finding neural activations in the core ToM network and the limbic–paralimbic network. In addition, we predicted finding a neural response in ToM ancillary circuits involving executive frontal loops.
Based on the ToM circuits depicted in the study by Abu-Akel and Shamay-Tsoory (2011) , we found no significant neural activation during implicit reasoning on the ESCoT social interaction animations. The lack of activation, which is in contrast with previous studies ( Wolf et al., 2010 ; Jacoby et al., 2016 ), may be related to the generic social instruction (“ focus on the social interactions” ) provided to participants before viewing the movie. In fact, previous studies ( Wolf et al., 2010 ; Jacoby et al., 2016 ) used a specific open-ended ToM question as their instruction (“ What is the character thinking?” ). It could be argued that the generic instruction we provided (“ focus on the social interactions ”) may not necessarily direct a participant’s attention to making inferences about mental states, but also different social cues, producing a consequent general social cognition neural pattern in both conditions (ToM and PI). Reversely, the generic instruction prompting physical inference “ focus on elements in the scene ” might not preclude ToM reasoning, and participants could have been similarly engaged in social cognition operations in both ToM and control conditions.
The results of the explicit ToM reasoning demonstrated different activation patterns related to the two response modalities: the open- (silent) and closed-ended answers. The neural activations related to ToM silent answers (contrast 2) were exclusively confined to the left hemisphere and captured significant activations located in the TP and STS (BA 21, 22, 38), suggesting the involvement of the core ToM and limbic–paralimbic networks, devoted to mental state representation and attribution ( Abu-Akel and Shamay-Tsoory, 2011 ). During the ToM closed-ended answering (contrast 3), the neural pattern extended bilaterally in the core and limbic–paralimbic ToM networks ( Abu-Akel and Shamay-Tsoory, 2011 ) and involved additional brain areas of the cognitive and affective execution loops. This brain pattern resembles and extends the one reported by Wolf et al. (2010) during naturalistic social movie tasks in fMRI. The wider neural pattern of closed-ended answers may be linked to the higher specificity of these items compared to the silent questions. In fact, in contrast with closed-ended ones, the silent questions do not prompt reference to a targeted mental state, with consequent interindividual differences in attentional focus and brain activation. In fact, by inviting the participants to silently answer, the spontaneous fluctuation of attention and brain activity (i.e., mind wandering, Braboszcz and Delorme, 2011 ) may be barely controlled and potentially explains the broader activation of closed-ended than silent answers in eliciting ToM neural patterns. The observed interindividual differences could also be explained by a broader search elicited by an open-ended question versus a closed-ended question, thus resulting in a more varied range of possible responses. The reduced specificity of the silent answer could explain the lack of activations in ToM networks observed during affective ToM answering (contrast 4) and the restricted extension of the neural pattern during cognitive ToM reasoning (contrast 6). Extended activation during multiple-choice answers might also reflect a major recruitment of cognitive processes than silent answers. As a previous fMRI study on mentalizing suggested ( Wolf et al., 2010 ), these answer modes require additional operations, such as interpreting the alternatives, selecting the correct answers, and extensive reading comprehension. These elements concur with higher cognitive demands and task difficulty, plausibly strengthening the brain response. We may assume that to study selective neural patterns within the ToM networks, multiple-choice answers, assuring a more effective neural response, are preferable.
The lack of activation during affective ToM (contrast 4), as opposed to a restricted minimal pattern during cognitive ToM silent answers, might be ascribed, according to our supplementary analyses, to higher inter-subject variability in affective ToM reasoning resulting in a more widespread and less consistent neural pattern component (see Supplementary Figures S5, S7 ). These distinct patterns may be partially explained by the different types of mental states on which the subject is invited to reflect emotions versus thoughts. In fact, a previous study ( Drobyshevsky et al., 2006 ) exploring the sensitivity of common fMRI tasks assessing different neurocognitive domains reported poor sensitivity for the task on emotional function, which did not monitor the subject’s performance.
We found that closed answering enabled distinct neural patterns related to affective and cognitive mental state reasoning. The neural activation of affective ToM (contrast 5) included bilaterally the core and limbic–paralimbic networks, including the precunei, anterior superior temporal sulci, and TPs (BA 7, 21, 38). The involvement of the core network extended to the posterior portion of the STS only in the left hemisphere. The significant cluster of activation included some regions of the affective and cognitive execution loops: the left inferior frontal gyrus (pars orbitalis and triangularis, BA 47), the insula, and the middle frontal gyrus. This pattern of activation resembles the brain network involved in affective mental state representation, attribution, and application ( Abu-Akel and Shamay-Tsoory, 2011 ). Interestingly, the neural activation cluster located in the insula confirms the specific involvement of emotional content and social behavior processing during the execution of an affective naturalistic ToM task ( Henry et al., 2016 ; de Oliveira-Souza and Moll, 2019 ).
Concerning the cognitive mental state neural patterns (contrast 7), the closed-ended answers yielded brain activations located only in the core ToM network, including the bilateral TPJ and precunei (BA 39, 7). Again, the ToM core network for mental state representation was effectively elicited as expected, but the limbic–paralimbic circuit and the frontal loop supporting cognitive mental state deployment were not included. The lack of involvement of the frontal brain areas may be related to several aspects. First, these areas may be recruited both in physical inference and ToM answering using a complex ecological stimulus. The absence of the cognitive frontal circuit could be ascribed to the preserved cognitive level of participants (healthy adults) included in the study, plausibly showing a high level of frontal executive functioning. Preserved and high social cognition processes may lead to selective involvement of specific ToM circuits but not the executive control ones. In addition, it is worth noting that the task itself requires reasoning on the mental states of social events that have already occurred, and, unlike other tests, it does not involve inferring or anticipating future intentions and behaviors of the characters, which is likely to engage the frontal loop. A recent meta-analysis ( Schurz et al., 2021 ) presented distinct patterns of neural activation based on social cognition test stimuli, proposing a three clustering solution: cognitive (ToM), affective (empathy), and intermediate domains. According to the present results, the ESCoT belongs to the intermediate cluster, bridging between the different domains of cognitive ToM and empathy. The intermediate positioning of ESCoT may be linked to its intrinsically ecological nature. In fact, by showing everyday life interactions, cognitive and affective ToM reasoning might be at least in part simultaneously elicited to properly interpret the social dynamics.
Finally, regarding the core ToM network activation during affective and cognitive ToM answering, a distinct neural pattern was also observed in the temporal areas. Especially the STS activation (BA 21/22) was found only during the affective ToM answering, while the TPJ involvement (BA 39) was observed exclusively in the cognitive ToM reasoning. These findings are further confirmed by explorinsg a direct comparison between the cognitive and affective ToM neural patterns (contrasts 8–11). In fact, affective ToM revealed neural activation located in the STS when explicit ToM reasoning was explored using closed-ended answering, while cognitive ToM reasoning relied on the activation of the bilateral TPJ when explicit ToM reasoning was tested using silent answering.
The TPJ has been widely reported as a crucial hub for the switching between self-perspective and others’ viewpoint during mentalizing tasks ( Decety and Sommerville, 2003 ; Uddin et al., 2005 ; Corbetta et al., 2008 ), playing a mediating role between self and others’ perspectives ( Schulte-Rüther et al., 2007 ). With the ESCoT scenarios, participants are invited to reflect on the mental states of characters who interact in a specific context, which is influenced by social norm adhesion or violation. When participants are prompted to reason on the affective mental states of the injured character in the scenario (e.g., the old woman who does not receive help from the young man), attention was easily directed to that character with whom the participant was prone to empathize, resulting in neural activation confined in the STS. Instead, when the participant is invited to reason on the thoughts and expectations of the injured character (i.e., in the previous example, did the young man behave as the old woman expected?), the level of complexity increases because it requires the switching to others’ viewpoints. In fact, the participant likely compares the characters’ violated expectations, in line with their own, with the intentions of the other character who violated those expectations. In this case, we observed major involvement of TPJ, as previously reported.
Another explanation might be related to previous studies supporting that the ToM circuit is prone to respond more to unpredicted (violation) than predicted (adhesion) information ( Cloutier et al., 2011 ; Dungan et al., 2016 ), in light of the predictive coding view of the social brain. In addition, evidence highlighted an enhanced activity of the bilateral TPJ when mental state information is relevant for moral judgment ( Young and Waytz, 2013 ). Especially, enhanced activations in the TPJ are observed when an immoral behavior is shown ( Kim et al., 2021 ) compared to a moral social comportment. A suggested explanation is the perception of immoral behavior as containing more intents than moral ones ( Brambilla et al., 2019 ), plausibly recruiting a broader neural circuit. Overall, the role of ToM in moral cognition has been reported in the literature ( Turiel, 1983 ). In fact, reasoning on people’s intentionality inflects the moral judgment when the individual is wondering whether to blame an agent’s behavior or not ( Knobe, 2005 ).
The adaptation of the ESCoT into an fMRI task was not without limitations which should be addressed in future studies, especially involving aging or clinical populations. First, the ToM silent answering resulted in poor neural activation as previously demonstrated ( Wolf et al., 2010 ). Therefore, only closed-ended questions should be included in future versions. The modification will also shorten the overall duration of the experiment. In addition, the high socio-educational level of participants may have partly prevented the generalization of the observed results. Moreover, the differentiation of the neural underpinnings related to the adhesion or violation of the social norms depicted in the social interaction animations was not investigated in this study, which may potentially affect ToM mechanisms. Future contributions should address these aspects to explore and deepen the knowledge of the neural correlates involved in social cognition deficits. Future studies could use this version of the ESCoT in clinical settings to study ToM network in different pathologies at risk or with social cognition deficits. This could include neurodegenerative conditions, schizophrenia, or developmental disorders. In addition, the task could be used to evaluate neuroplasticity or reorganization after ToM training such as those used in rehabilitative settings. Finally, one last aspect that should not be overlooked when exploring higher-level cognitive domains such as ToM reasoning is the issue of individual variability ( Saxe and Kanwisher, 2003 ; Saxe and Powell, 2006 ). To address this issue, standard GLM factorial analysis should be integrated with further analysis assessing the consistency of brain responses across subjects. This has been addressed in the present study by performing an additional analysis with the methods proposed in a study by Seghier and Price (2016) , and the findings corroborate the group-level results. Specifically, concerning the two ToM components, the differential involvement of TPJ in cToM and STS in aToM was substantiated.
Finally, it is worth mentioning that our results prevented us from investigating online mentalizing reasoning when the subject is involved in first person social interactions. Future contributions might consider adopting different acquisition settings such as hyper-scanning (e.g., Bazán and Amaro, 2022 for a review) to study neural patterns during social interaction.
In conclusion, the present study investigated the brain mechanisms involved in individual mentalizing reasoning in real-life social interactions. The ESCoT stimuli were particularly effective in evoking ToM core neural underpinnings and elicited executive frontal loops. These results support the application of the ESCoT as a sensitive test of social cognition and provide further insights into the neural regions involved in social cognition.

What social factors are involved with the development of aggressive thoughts and behaviours? Is aggression socially-defined? Do different societies have differing definitions of aggression?
There has recently been a significant amount of research conducted on the influence of video games and television on aggression and violent behaviour.
Some research has been based on high-profile case studies, such as the aggressive murder of Jamie Bulger in 1993 by two children (Robert Thompson and Jon Venables). There is also a significant body of experimental research.
This is a huge area of research with lots of crossover into developmental psychology. What draws people together? How do people connect emotionally? What is love? What is friendship? What happens if someone doesn’t form an attachment with a parental figure?
This area includes research on attachment styles (at various stages of life), theories of love, friendship and attraction.
Attitudes are a relatively enduring and general evaluation of something. Individuals hold attitudes on everything in life, from other people to inanimate objects, groups to ideologies.
Attitudes are thought to involve three components: (1) affective (to do with emotions), (2) behavioural, and (3) cognitive (to do with thoughts).
Research on attitudes can be closely linked to Prejudice (see below).
Perhaps the most famous study of authority is Milgram’s (1961) Obedience to Authority . This research area has grown into a far-reaching and influential topic.
Research considers both positive and negative elements of authority, and applied psychology studies consider the role of authority in a particular social setting, such as advertising, in the workplace, or in a classroom.
The Psychology of Crowds (Le Bon, 1895) paved a path for a fascinating area of social psychology that considers the social group as an active player.
Groups tend to act differently from individuals, and specific individuals will act differently depending on the group they are in.
Social psychology research topics about groups consider group dynamics, leadership (see above), group-think and decision-making, intra-group and inter-group conflict, identities (see below) and prejudices (see below).
Gordon Allport’s (1979) ‘The Nature of Prejudice’ is a seminal piece on group stereotyping and discrimination.
Social psychologists consider what leads to the formation of stereotypes and prejudices. How and why are prejudices used? Why do we maintain inaccurate stereotypes? What are the benefits and costs of prejudice?
This interesting blog post on the BPS Digest Blog may provide some inspiration for research into prejudice and political uncertainty.
Behaviours are only pro- or anti-social because of social norms that suggest so. Social Psychologists therefore investigate the roots of these behaviours as well as considering what happens when social norms are ignored.
Within this area of social psychology, researchers may consider why people help others (strangers as well as well as known others). Another interesting question regards the factors that might deter an individual from acting pro-socially, even if they are aware that a behaviour is ‘the right thing to do’.
The bystander effect is one such example of social inaction.
Tajfel and Turner (1979) proposed Social Identity Theory and a large body of research has developed out of the concepts of self and social identity (or identities).
Questions in this area include: what is identity? What is the self? Does a social identity remain the same across time and space? What are the contributory factors to an individual’s social identity?
Zimbardo’s (1972) Stanford Prison Experiment famously considered the role of social identities.
Research in this area also links with work on groups (see above), social cognition (see below), and prejudices (see above).
Social cognition regards the way we think and use information. It is the cross-over point between the fields of social and cognitive psychology.
Perhaps the most famous concept in this area is that of schemas – general ideas about the world, which allow us to make sense of new (and old) information quickly.
Social cognition also includes those considering heuristics (mental shortcuts) and some cognitive biases.
This is one of the first areas of social psychology that most students learn. Remember the social conformity work by Asch (1951) on the length of lines?
Other social psychology research topics within this area include persuasion and peer-pressure.
Social Representations (Moscovici, 1961) ‘make something unfamiliar, or unfamiliarity itself, familiar’ (Moscovici, 1984). This is a theory with its academic roots in Durkheim’s theory of collective representations.
Researchers working within this framework consider the social role of knowledge. How does information translate from the scientific realm of expert knowledge to the socially accessible realm of the layperson? How do we make sense of new information? How do we organise separate and distinct facts in a way that make sense to our needs?
One of the most famous studies using Social Representations Theory is Jodelet’s (1991) study of madness.

The exploration of cognitive psychology research paper topics presents an unparalleled opportunity to delve into the mechanisms that underpin human cognition and behavior. Each category and topic not only contributes to the rich tapestry of cognitive psychology but also holds the potential for groundbreaking research that can influence educational practices, therapeutic approaches, and policy development. Students are encouraged to engage deeply with these topics, leveraging their curiosity and analytical skills to advance the field and contribute valuable insights into the complex world of human cognition.
Cognitive Psychology as a Discipline
The development of cognitive psychology marked a significant shift from the behaviorist perspective that dominated psychology for much of the early 20th century, which largely ignored mental processes. Instead, cognitive psychology focuses on understanding internal mental states and processes, utilizing this understanding to explain behavioral patterns. This focus on the internal workings of the mind has not only expanded the scope of psychological research but has also had practical applications in various fields such as education, mental health, artificial intelligence, and more, demonstrating the discipline’s broad impact.
The Importance of Research in Expanding Our Understanding of Cognitive Processes
Research in cognitive psychology plays a crucial role in expanding our understanding of the human mind and behavior. Through empirical studies, experiments, and longitudinal research, cognitive psychologists seek to build a body of knowledge about how cognitive processes work, how they change over time, and how they can be improved or altered. This research is fundamental to developing new theories of cognition that can explain complex human behaviors and cognitive anomalies.
One of the key contributions of cognitive psychology research is the development of models that describe various cognitive processes. For example, research on memory has led to the formulation of the multi-store model, which outlines how information flows from sensory memory to short-term memory and finally to long-term memory. Similarly, studies on decision-making and problem-solving have introduced several cognitive biases that influence human judgment, such as confirmation bias and availability heuristic. These models and theories are crucial for understanding the limitations and capabilities of human cognition, informing approaches in education, cognitive therapy, and even interface design in technology.
Moreover, cognitive psychology research has a significant impact on diagnosing and treating cognitive disorders. Studies on neurocognitive disorders, such as Alzheimer’s disease and attention deficit hyperactivity disorder (ADHD), provide insights into their cognitive underpinnings, leading to better diagnostic criteria and treatment options. Research in this field also supports the development of cognitive rehabilitation techniques and cognitive-behavioral therapies, demonstrating its vital role in improving mental health and cognitive function.
The Variety of Research Topics within Cognitive Psychology and Their Relevance to Real-World Applications
Cognitive psychology encompasses a wide array of research topics, each with direct implications for real-world applications. For instance, research in perception and sensation enhances our understanding of how sensory information is interpreted by the brain, influencing fields such as marketing, design, and even virtual reality development. Studies on attention and information processing have led to improvements in educational strategies, helping to develop teaching methods that align with cognitive load theory and the attentional needs of students.
Language and cognition research has profound implications for language teaching methodologies, speech therapy, and understanding language disorders. Insights from this research help in designing interventions for individuals with dyslexia or aphasia, facilitating better communication and learning outcomes. Additionally, the study of problem-solving and decision-making is pivotal for the development of artificial intelligence, providing algorithms with models of human cognition that can be simulated in computational systems.
The exploration of memory and recall has applications in legal settings, especially in eyewitness testimony and the reliability of memory. Cognitive psychology’s findings on the malleability of human memory and the conditions under which memories are accurately or inaccurately recalled are crucial for informing judicial processes and policies. Furthermore, the study of social cognition, which examines how individuals perceive, think about, and interact with others, is essential for understanding social behavior, improving interpersonal relationships, and addressing societal issues such as prejudice and discrimination.
Recent Advancements in Cognitive Psychology Research
Recent advancements in cognitive psychology research have been facilitated by technological innovations, allowing for more sophisticated exploration of cognitive processes. Neuroimaging techniques such as fMRI and PET scans have provided insights into the neural substrates of various cognitive functions, bridging the gap between cognitive psychology and neuroscience. These advancements have led to a deeper understanding of how different brain regions are involved in specific cognitive tasks, such as memory recall or language processing.
Additionally, the integration of machine learning and artificial intelligence in cognitive research has opened new avenues for analyzing large datasets, leading to more nuanced understandings of cognitive patterns and anomalies. This intersection of cognitive psychology and computational modeling has also advanced the development of intelligent systems capable of mimicking human cognitive functions, from language understanding to pattern recognition.
Another significant advancement is in the realm of cognitive enhancement, where research is exploring ways to improve cognitive functions through pharmacological means, cognitive training exercises, and even non-invasive brain stimulation techniques. These studies hold the potential for significant impacts on education, mental health treatment, and the general enhancement of cognitive abilities in healthy individuals.
Ethical Issues Inherent in Cognitive Psychology Research
Cognitive psychology research, while offering vast potential for understanding and enhancing human cognition, also presents several ethical considerations. Issues such as informed consent, privacy, and the potential for misuse of cognitive data are paramount concerns. The use of neuroimaging and other biometric data, for instance, raises questions about the privacy of mental states and the potential for such information to be used in ways that could infringe on individual rights or autonomy.
Additionally, the ethical implications of cognitive enhancement and the potential societal impacts of creating disparities between those who have access to cognitive enhancement technologies and those who do not are areas of ongoing debate. Cognitive psychology researchers must navigate these ethical waters carefully, ensuring that their work promotes the welfare and dignity of all individuals while advancing scientific knowledge.
Future Directions for Research in Cognitive Psychology
The future of cognitive psychology research promises further integration with neuroscience, the application of advanced computational models, and the exploration of how cognitive processes evolve in a rapidly changing digital world. An exciting direction for future research is the investigation of how digital technologies, such as smartphones and social media, are affecting cognitive development, attention spans, and social cognition. Understanding these impacts is crucial for developing strategies to mitigate potential negative effects while harnessing technology’s power to enhance cognitive function.
Another area of future research is the exploration of individual differences in cognition, understanding how genetic, environmental, and cultural factors contribute to the diversity of cognitive processes among individuals. This line of research holds the promise of personalizing educational and therapeutic approaches to cater to individual cognitive profiles.
The Transformative Potential of Research in Cognitive Psychology
Research in cognitive psychology holds transformative potential for numerous aspects of human life, from education and mental health to technology and social interaction. By continuing to explore the intricacies of cognitive processes and their neural underpinnings, cognitive psychology can contribute to a deeper understanding of what it means to be human. The ongoing exploration of cognitive phenomena not only enriches our knowledge of the mind but also translates into practical applications that can improve individual well-being and societal health. As cognitive psychology advances, its research continues to shape our world, demonstrating the enduring power of understanding the human mind.

From the very early days of the pandemic, brain fog emerged as a significant health condition that many experience after COVID-19.
Brain fog is a colloquial term that describes a state of mental sluggishness or lack of clarity and haziness that makes it difficult to concentrate, remember things and think clearly.
Fast-forward four years and there is now abundant evidence that being infected with SARS-CoV-2 – the virus that causes COVID-19 – can affect brain health in many ways .
In addition to brain fog, COVID-19 can lead to an array of problems , including headaches, seizure disorders, strokes, sleep problems, and tingling and paralysis of the nerves, as well as several mental health disorders .
A large and growing body of evidence amassed throughout the pandemic details the many ways that COVID-19 leaves an indelible mark on the brain. But the specific pathways by which the virus does so are still being elucidated, and curative treatments are nonexistent.
Now, two new studies published in the New England Journal of Medicine shed further light on the profound toll of COVID-19 on cognitive health .
I am a physician scientist , and I have been devoted to studying long COVID since early patient reports about this condition – even before the term “long COVID” was coined. I have testified before the U.S. Senate as an expert witness on long COVID and have published extensively on this topic.
Here are some of the most important studies to date documenting how COVID-19 affects brain health:
Large epidemiological analyses showed that people who had COVID-19 were at an increased risk of cognitive deficits , such as memory problems.
Imaging studies done in people before and after their COVID-19 infections show shrinkage of brain volume and altered brain structure after infection .
A study of people with mild to moderate COVID-19 showed significant prolonged inflammation of the brain and changes that are commensurate with seven years of brain aging .
Severe COVID-19 that requires hospitalization or intensive care may result in cognitive deficits and other brain damage that are equivalent to 20 years of aging .
Laboratory experiments in human and mouse brain organoids designed to emulate changes in the human brain showed that SARS-CoV-2 infection triggers the fusion of brain cells . This effectively short-circuits brain electrical activity and compromises function.
Autopsy studies of people who had severe COVID-19 but died months later from other causes showed that the virus was still present in brain tissue . This provides evidence that contrary to its name, SARS-CoV-2 is not only a respiratory virus, but it can also enter the brain in some individuals. But whether the persistence of the virus in brain tissue is driving some of the brain problems seen in people who have had COVID-19 is not yet clear.
Studies show that even when the virus is mild and exclusively confined to the lungs, it can still provoke inflammation in the brain and impair brain cells’ ability to regenerate .
COVID-19 can also disrupt the blood brain barrier , the shield that protects the nervous system – which is the control and command center of our bodies – making it “leaky.” Studies using imaging to assess the brains of people hospitalized with COVID-19 showed disrupted or leaky blood brain barriers in those who experienced brain fog.
A large preliminary analysis pooling together data from 11 studies encompassing almost 1 million people with COVID-19 and more than 6 million uninfected individuals showed that COVID-19 increased the risk of development of new-onset dementia in people older than 60 years of age.
Most recently, a new study published in the New England Journal of Medicine assessed cognitive abilities such as memory, planning and spatial reasoning in nearly 113,000 people who had previously had COVID-19. The researchers found that those who had been infected had significant deficits in memory and executive task performance.
This decline was evident among those infected in the early phase of the pandemic and those infected when the delta and omicron variants were dominant. These findings show that the risk of cognitive decline did not abate as the pandemic virus evolved from the ancestral strain to omicron.
In the same study, those who had mild and resolved COVID-19 showed cognitive decline equivalent to a three-point loss of IQ. In comparison, those with unresolved persistent symptoms, such as people with persistent shortness of breath or fatigue, had a six-point loss in IQ. Those who had been admitted to the intensive care unit for COVID-19 had a nine-point loss in IQ. Reinfection with the virus contributed an additional two-point loss in IQ, as compared with no reinfection.
Generally the average IQ is about 100. An IQ above 130 indicates a highly gifted individual, while an IQ below 70 generally indicates a level of intellectual disability that may require significant societal support.
To put the finding of the New England Journal of Medicine study into perspective, I estimate that a three-point downward shift in IQ would increase the number of U.S. adults with an IQ less than 70 from 4.7 million to 7.5 million – an increase of 2.8 million adults with a level of cognitive impairment that requires significant societal support.
Another study in the same issue of the New England Journal of Medicine involved more than 100,000 Norwegians between March 2020 and April 2023. It documented worse memory function at several time points up to 36 months following a positive SARS-CoV-2 test.
Taken together, these studies show that COVID-19 poses a serious risk to brain health, even in mild cases, and the effects are now being revealed at the population level.
A recent analysis of the U.S. Current Population Survey showed that after the start of the COVID-19 pandemic, an additional 1 million working-age Americans reported having “serious difficulty” remembering, concentrating or making decisions than at any time in the preceding 15 years. Most disconcertingly, this was mostly driven by younger adults between the ages of 18 to 44.
Data from the European Union shows a similar trend – in 2022, 15% of people in the EU reported memory and concentration issues .
Looking ahead, it will be critical to identify who is most at risk. A better understanding is also needed of how these trends might affect the educational attainment of children and young adults and the economic productivity of working-age adults. And the extent to which these shifts will influence the epidemiology of dementia and Alzheimer’s disease is also not clear.
The growing body of research now confirms that COVID-19 should be considered a virus with a significant impact on the brain. The implications are far-reaching, from individuals experiencing cognitive struggles to the potential impact on populations and the economy.
Lifting the fog on the true causes behind these cognitive impairments, including brain fog, will require years if not decades of concerted efforts by researchers across the globe. And unfortunately, nearly everyone is a test case in this unprecedented global undertaking.

All languages have words like 'this' and 'that' to distinguish between referents that are 'near' and 'far'. Languages like English or Hebrew have two of these 'demonstratives'. Languages like Spanish or Japanese use a three-word system. For instance, in Spanish, 'este' signals something close to the speaker, 'ese' signals something far from the speaker but close to the listener, and 'aquel' signals something far from both.
"The reason why we were interested in demonstratives is because of their connection to social cognition: demonstratives are used to direct the listener's attention to a referent and establish joint attention," says MPI's Paula Rubio-Fernández, senior investigator and co-author of the study. "Engaging in joint attention is a uniquely human capacity that links language to social cognition in communication. Because demonstratives are universal, emerged early in language evolution and are acquired early in child development, they offer an ideal test case for the interdependence between these two fundamentally human capacities."
There is debate about whether directing the listener's attention -- the 'mentalistic' representation -- is part of the meaning (semantics) of demonstratives, or whether it arises from general principles of social cognition (pragmatics). The researchers used computational modelling and experiments with speakers of ten different languages from eight different language groups to investigate this question.
In an online task, participants saw pictures of a 'speaker' requesting an object from a 'listener', who was standing on the other side of a long table. The participants were asked to take the role of the speaker, and select a demonstrative from their native language to request the object ("Now I need …"). In the pictures, the listener was either already looking at the intended object or looking at one of four other objects (closer or further from the target). If directing attention is part of the meaning of demonstratives, all speakers should be sensitive to a listener's initial attention when selecting a demonstrative. However, there should also be variation across languages.
Results showed that participants were not only sensitive to the location of the target but also to the listener's attention. As expected, the meaning of demonstratives varied within and across languages. For example, the 'near' demonstrative (such as English 'this one') sometimes had a spatial meaning ('the one close to me'). But it also had a joint attention meaning ('the one we are both looking at') or a 'mentalistic' meaning ('the one over here'), directing the listener's attention towards the speaker. Interestingly, speakers of languages with a three-word system used the medial word (such as Spanish 'ese') to indicate joint attention.
"Our work sheds light on the interface between social cognition and language. We show that representations of interlocutor attention are embedded into one of the most basic word classes that appear across all languages: demonstratives," concludes Rubio-Fernández. "Our work also shows through Bayesian computational modelling that this form of attention manipulation cannot be explained via pragmatic reasoning external to the linguistic system, suggesting that mentalistic representations are embedded in a universal component of language".

What is post-traumatic stress disorder (ptsd).
Post-traumatic stress disorder (PTSD) is a disorder that develops in some people who have experienced a shocking, scary, or dangerous event.
It is natural to feel afraid during and after a traumatic situation. Fear is a part of the body’s “fight-or-flight” response, which helps us avoid or respond to potential danger. People may experience a range of reactions after trauma, and most people recover from initial symptoms over time. Those who continue to experience problems may be diagnosed with PTSD.
Anyone can develop PTSD at any age. This includes combat veterans and people who have experienced or witnessed a physical or sexual assault, abuse, an accident, a disaster, or other serious events. People who have PTSD may feel stressed or frightened, even when they are not in danger.
Not everyone with PTSD has been through a dangerous event. Sometimes, learning that a friend or family member experienced trauma can cause PTSD.
According to the National Center for PTSD , a program of the U.S. Department of Veterans Affairs, about six out of every 100 people will experience PTSD at some point in their lives. Women are more likely to develop PTSD than men. Certain aspects of the traumatic event and some biological factors (such as genes) may make some people more likely to develop PTSD.
Symptoms of PTSD usually begin within 3 months of the traumatic event, but they sometimes emerge later. To meet the criteria for PTSD, a person must have symptoms for longer than 1 month, and the symptoms must be severe enough to interfere with aspects of daily life, such as relationships or work. The symptoms also must be unrelated to medication, substance use, or other illness.
The course of the disorder varies. Some people recover within 6 months, while others have symptoms that last for 1 year or longer. People with PTSD often have co-occurring conditions, such as depression, substance use, or one or more anxiety disorders.
After a dangerous event, it is natural to have some symptoms. For example, some people may feel detached from the experience, as though they are observing things rather than experiencing them. A mental health professional who has experience helping people with PTSD, such as a psychiatrist, psychologist, or clinical social worker, can determine whether symptoms meet the criteria for PTSD.
To be diagnosed with PTSD, an adult must have all of the following for at least 1 month:
Thoughts and feelings can trigger these symptoms, as can words, objects, or situations that are reminders of the event.
Avoidance symptoms may cause people to change their routines. For example, some people may avoid driving or riding in a car after a serious car accident.
Arousal symptoms are often constant. They can lead to feelings of stress and anger and may interfere with parts of daily life, such as sleeping, eating, or concentrating.
Cognition and mood symptoms can begin or worsen after the traumatic event. They can lead a person to feel detached from friends or family members.
If you or someone you know is struggling or having thoughts of suicide, call or text the 988 Suicide and Crisis Lifeline at 988 or chat at 988lifeline.org . In life-threatening situations, call 911 .
Children and teens can have extreme reactions to trauma, but some of their symptoms may not be the same as those seen in adults. In children younger than age 6, these symptoms can include:
Older children and teens usually show symptoms more like those seen in adults. They also may develop disruptive, disrespectful, or destructive behaviors. Older children and teens may feel guilty for not preventing injury or deaths. They may also have thoughts of revenge.

Not everyone who lives through a dangerous event develops PTSD—many factors play a part. Some of these factors are present before the trauma; others become important during and after a traumatic event.
Risk factors that may increase the likelihood of developing PTSD include:
Resilience factors that may reduce the likelihood of developing PTSD include:
It is important for anyone with PTSD symptoms to work with a mental health professional who has experience treating PTSD. The main treatments are psychotherapy, medications, or a combination of psychotherapy and medications. A mental health professional can help people find the best treatment plan for their symptoms and needs.
Some people with PTSD, such as those in abusive relationships, may be living through ongoing trauma. In these cases, treatment is usually most effective when it addresses both the traumatic situation and the symptoms of PTSD. People who experience traumatic events or who have PTSD also may experience panic disorder , depression , substance use , or suicidal thoughts . Treatment for these conditions can help with recovery after trauma. Research shows that support from family and friends also can be an important part of recovery.
Psychotherapy (sometimes called talk therapy) includes a variety of treatment techniques that mental health professionals use to help people identify and change troubling emotions, thoughts, and behaviors. Psychotherapy can provide support, education, and guidance to people with PTSD and their families. Treatment can take place one on one or in a group and usually lasts 6 to 12 weeks but can last longer.
Some types of psychotherapy target PTSD symptoms, while others focus on social, family, or job-related problems. Effective psychotherapies often emphasize a few key components, including learning skills to help identify triggers and manage symptoms.
One common type of psychotherapy, called cognitive behavioral therapy, can include exposure therapy and cognitive restructuring:
The U.S. Food and Drug Administration (FDA) has approved two selective serotonin reuptake inhibitors (SSRIs), a type of antidepressant medication, for the treatment of PTSD. SSRIs may help manage PTSD symptoms such as sadness, worry, anger, and feeling emotionally numb. Health care providers may prescribe SSRIs and other medications along with psychotherapy. Some medications may help treat specific PTSD symptoms, such as sleep problems and nightmares.
People should work with their health care providers to find the best medication or combination of medications and the right dose. To find the latest information about medications, talk to a health care provider and visit the FDA website .
If you’re not sure where to get help, a health care provider can refer you to a licensed mental health professional, such as a psychiatrist or psychologist with experience treating PTSD. Find tips to help prepare for and get the most out of your visit and information about getting help .
The Substance Abuse and Mental Health Services Administration has a online treatment locator to help you find mental health services in your area.
Here are some things you can do to help yourself while in treatment:
If you know someone who may be experiencing PTSD, the most important thing you can do is to help that person get the right diagnosis and treatment. Some people may need help making an appointment with their health care provider; others may benefit from having someone accompany them to their health care visits.
If a close friend or relative is diagnosed with PTSD, you can encourage them to follow their treatment plan. If their symptoms do not get better after 6 to 8 weeks, you can encourage them to talk to their health care provider. You also can:
Clinical trials are research studies that look at new ways to prevent, detect, or treat diseases and conditions. The goal of clinical trials is to determine if a new test or treatment works and is safe. Although individuals may benefit from being part of a clinical trial, participants should be aware that the primary purpose of a clinical trial is to gain new scientific knowledge so that others may be better helped in the future.
Researchers at NIMH and around the country conduct many studies with patients and healthy volunteers. We have new and better treatment options today because of what clinical trials uncovered years ago. Talk to your health care provider about clinical trials, their benefits and risks, and whether one is right for you.

Using 286 research papers collected from Web of Science, ScienceDirect, SpringerLink, arXiv, and Google Scholar databases, a systematic review methodology was adopted to review and summarize the current challenges and potential future developments in data, algorithms, and evaluation aspects of RSs. It was found that RSs involve five major research topics, namely algorithmic improvement, domain applications, user behavior & cognition, data processing & modeling, and social impact & ethics. Collaborative filtering and hybrid recommendation techniques are mainstream. The performance of RSs is jointly limited by four types of eight data issues, two types of twelve algorithmic issues, and two evaluation issues. Notably, data-related issues such as cold start, data sparsity, and data poisoning, algorithmic issues like interest drift, device-cloud collaboration, non-causal driven, and multitask conflicts, along with evaluation issues such as offline data leakage and multi-objective balancing, have prominent impacts. Fusing physiological signals for multimodal modeling, defending against data poisoning through user information behavior, evaluating generative recommendations via social experiments, fine-tuning pre-trained large models to schedule device-cloud resource, enhancing causal inference with deep reinforcement learning, training multi-task models based on probability distributions, using cross-temporal dataset partitioning, and evaluating recommendation objectives across the full lifecycle are feasible solutions to address the aforementioned prominent challenges and unlock the power and value of RSs.The collected literature is mainly based on major international databases, and future research will further expand upon it.

1. Introduction. Human beings navigate the world by perceiving, attending to, and remembering incoming information within a framework of concepts such as ''number'' and ''cause.''. While these general abilities form the bedrock of any theory of cognition, social life presents cognitive scien-tists with a unique set of questions.
The fundamental assumption of social cognition research is the idea that internal mental representations of other persons and of social situations play a key causal role in shaping behavior.
Since the publication of Premack and Woodruff's classic paper introducing the notion of a 'theory of mind' (Premack and Woodruff in Behav Brain Sci 1(4):515-526, 1978), interdisciplinary research in social cognition has witnessed the development of theory-theory, simulation theory, hybrid approaches, and most recently interactionist and perceptual accounts of other minds. The ...
