Group-living creates stresses that, all else equal, naturally lead to group fragmentation, and hence loss of the benefits that group-living provides. How species that live in large stable groups counteract these forces is not well understood. I use comparative data on grooming networks and cognitive abilities in primates to show that living in large, stable groups has involved a series of structural solutions designed to create chains of ‘friendship’ (friends-of-friends effects), increased investment in bonding behaviours (made possible by dietary adjustments) to ensure that coalitions work effectively, and neuronally expensive cognitive skills of the kind known to underpin social relationships in humans. The first ensures that individuals synchronise their activity cycles; the second allows the stresses created by group-living to be defused; and the third allows a large number of weak ties to be managed. Between them, these create a form of multilevel sociality based on strong versus weak ties similar to that found in human social networks. In primates, these strategies appear successively at quite specific group sizes, suggesting that they are solutions to ‘glass ceilings’ that would otherwise limit the range of group sizes that animals can live in (and hence the habitats they can occupy). This sequence maps closely onto the grades now known to underpin the Social Brain Hypothesis and the fractal pattern that is known to optimise information flow round networks.

When people are asked to recall their social networks, theoretical and empirical work tells us that they rely on shortcuts, or heuristics. Cognitive social structures (CSSs) are multilayer social networks where each layer corresponds to an individual’s perception of the network. With multiple perceptions of the same network, CSSs contain rich information about how these heuristics manifest, motivating the question, Can we identify people who share the same heuristics? In this work, we propose a method for identifying cognitive structure across multiple network perceptions, analogous to how community detection aims to identify social structure in a network. To simultaneously model the joint latent social and cognitive structure, we study CSSs as three-dimensional tensors, employing low-rank nonnegative Tucker decompositions (NNTuck) to approximate the CSS—a procedure closely related to estimating a multilayer stochastic block model (SBM) from such data. We propose the resulting latent cognitive space as an operationalization of the sociological theory of social cognition by identifying individuals who share relational schema. In addition to modeling cognitively independent, dependent, and redundant networks, we propose a specific model instance and related statistical test for testing when there is social-cognitive agreement in a network: when the social and cognitive structures are equivalent. We use our approach to analyze four different CSSs and give insights into the latent cognitive structures of those networks.

Summary
This chapter discusses the growing body of research that examines the social cognitive processes of jurors used when making verdict or sentencing decisions. This includes the empirical findings related to priming ideas and attitudes and impression formation. The chapter then discusses heuristics, or cognitive “shortcuts,” that jurors employ during their decision-making processes in trials and deliberations. For instance, there is a tendency for jurors to over-rely on dispositional attributions, stereotypes, and schemas. Cognitive biases that jurors are prone to, such as the hindsight bias, the outcome bias, and counterfactual thinking, will also be discussed in the context of evaluating evidence and making verdict decisions, along with the potential of debiasing techniques. Finally, jurors’ biases and prejudices regarding factors, such as race, gender, and religion, and how they relate to decision-making are examined. The chapter also addresses areas of social cognition that have not yet been explored in current research and provides recommendations for future directions.

Background
People with schizophrenia on average are more socially isolated, lonelier, have more social cognitive impairment, and are less socially motivated than healthy individuals. People with bipolar disorder also have social isolation, though typically less than that seen in schizophrenia. We aimed to disentangle whether the social cognitive and social motivation impairments observed in schizophrenia are a specific feature of the clinical condition v. social isolation generally.
MethodsWe compared four groups (clinically stable patients with schizophrenia or bipolar disorder, individuals drawn from the community with self-described social isolation, and a socially connected community control group) on loneliness, social cognition, and approach and avoidance social motivation.
ResultsIndividuals with schizophrenia (n = 72) showed intermediate levels of social isolation, loneliness, and social approach motivation between the isolated (n = 96) and connected control (n = 55) groups. However, they showed significant deficits in social cognition compared to both community groups. Individuals with bipolar disorder (n = 48) were intermediate between isolated and control groups for loneliness and social approach. They did not show deficits on social cognition tasks. Both clinical groups had higher social avoidance than both community groups
ConclusionsThe results suggest that social cognitive deficits in schizophrenia, and high social avoidance motivation in both schizophrenia and bipolar disorder, are distinct features of the clinical conditions and not byproducts of social isolation. In contrast, differences between clinical and control groups on levels of loneliness and social approach motivation were congruent with the groups' degree of social isolation.

Objective:
Classical galactosemia (CG) is an inborn error of galactose metabolism. Many CG patients suffer from long-term complications including poor cognitive functioning. There are indications of social dysfunction but limited evidence in the literature. Therefore, this study aims to improve our understanding of social competence in CG by investigating social cognition, neurocognition and emotion regulation.
Methods:A comprehensive (neuro)psychological test battery, including self and proxy questionnaires, was administered to CG patients without intellectual disability. Social cognition was assessed by facial emotion recognition, Theory of Mind and self-reported empathy. Standardised results were compared to normative data of the general population.
Results:Data from 23 patients (aged 8–52) were included in the study. On a group level, CG patients reported satisfaction with social roles and no social dysfunction despite the self-report of lower social skills. They showed deficits in all aspects of social cognition on both performance tests (emotion recognition and Theory of Mind) and self-report questionnaires (empathy). Adults had a lower social participation than the general population. Parents reported lower social functioning, less adaptive emotion regulation and communication difficulties in their children. Individual differences in scores were present.
Conclusion:This study shows that CG patients without intellectual disability are satisfied with their social competence, especially social functioning. Nevertheless, deficits in social cognition are present in a large proportion of CG patients. Due to the large variability in scores and discrepancies between self- and proxy-report, an individually tailored, comprehensive neuropsychological assessment including social cognition is advised in all CG patients. Treatment plans need to be customised to the individual patient.

Objective:
Multiple sclerosis (MS) is associated with cognitive and social cognitive deficits. Social cognition impairments may include difficulty with facial expression and emotion recognition. People with MS (PwMS) may also not be aware of their cognitive challenges as demonstrated through discrepant objective and subjective assessments. Research recently conducted in demyelinated mouse models demonstrated that metformin, a drug typically used to treat type II diabetes mellitus (DMII), promotes remyelination and reverses existent social cognition impairment by repressing the monoacylglycerol lipase (MgII) enzyme in the brain. We aim to translate this basic science research and are conducting a pilot study to determine if metformin improves social cognition in PwMS. This project will compare social cognition in those with MS and comorbid DMII who are treated with metformin and those who are not. For the purposes of this interim data analysis, we collapse across both MS groups who are, and who are not, treated with metformin. The current objective is to evaluate the relationship between subjective (i.e., perceived empathy), objective social cognition and information processing speed (IPS) in PwMS and co-morbid diabetes.
Participants and Methods:Preliminary data on 15 PwMS are included. Participants completed a demographic questionnaire, a cognitive assessment battery, an objective social cognition assessment and self-report questionnaires. These questionnaires assessed subjective social cognition, fatigue, mood, and disability level.
Results:Preliminary results showed that IPS was positively correlated with the affective empathy domain of social cognition, r = .53, p = .04. Additionally, IPS was positively correlated with objective social cognition, r = .71, p = 003. Follow-up regression analyses demonstrated that IPS predicted objective social cognition, R2 = .71, SE = 3.04, F(1,13) = 13.36, p = .003 and subjective social cognition, R2 = .53, SE = 5.39, F(1,13) = 4.97, p = .04. However, subjective and objective measures of social cognition were not correlated, p > .05 and remained uncorrelated when IPS was controlled for, p > .05.
Conclusions:A majority of the variance in social perception is explained by IPS, suggesting that how quickly one can think may be a fundamental cognitive process to allow optimal functioning in social situations. While the reason for the relationship between IPS and subjective social cognition is perhaps less apparent, it may reflect a more global cognitive compromise that impacts both cognitive and social processes. This lends support to the Relative Consequence Model that suggests IPS deficits are a fundamental cognitive deficit underlying other more complex cognitive processes. The lack of correlation between subjective perception of empathy and objective social cognition requires further exploration and could potentially be related to some individuals with MS having a diminished ability to judge their own social proficiency. Further analyses with a larger sample will be conducted to assess group differences in social cognitive outcomes and MgII levels between metformin and non-metformin groups. If PwMS who take metformin have better social cognition compared to PwMS who do not take metformin, Mgll levels can be used as a biomarker to guide metformin treatment with the goal of improving social cognition.

Objective:
Abnormalities in social and emotional behavior are the major diagnostic criteria for behavioral variant frontotemporal dementia (bvFTD). Investigators have attributed their behavioral disturbances to disease in mesial prefrontal and related networks, such as the salience network. This study examined the main neural correlates of informant-reported socioemotional dysfunction among patients with bvFTD compared to those with early-onset (before age 65) Alzheimer's Disease (EOAD).
Participants and Methods:Participants included 13 patients with bvFTD and their caregivers and 18 patients with EOAD and their caregivers. The caregivers consisted of a spouse, family member, or other informant who resided with the patient. They completed the informant-based Socioemotional Dysfunction Scale (SDS), a 40-item scale which rates common disturbances in social and emotional behavior on a five-point Likert scale (1-5). The patients underwent magnetic resonance imaging (MRI) with tensor-based morphometry (TBM) analysis of the 3D T1-weighted MRI scans. Computations of mean Jacobian values within select regions of interest (ROIs) in frontal and temporal lobes generated numerical summaries of regional volumes, and voxel-wise regressions created 3D statistical maps of the association between tissue volume and SDS total scores. Statistical analyses included independent samples t-tests group differences in ROIs and SDS scores, Pearson correlations between SDS scores and brain volumes, and multiple regression of ROIs with SDS scores and group as predictor variables.
Results:Compared to the EOAD group, the bvFTD group had significantly higher SDS scores (p < .001; d = 2.24), smaller frontal lobe volumes (specifically dorsolateral-prefrontal cortex, p = .003; d = 1.24), and larger temporal lobe volumes (specifically hippocampus, p = .014; d = 0.979). Within the bvFTD group, higher SDS scores were associated with a smaller right anterior temporal lobe (ATL; p = .005; r = -.729), especially the lateral ATLs (p = .002; r = -.776), and a smaller bilateral orbitofrontal cortex (OFC; p = .016; r = -.650). In contrast, within the EOAD group, higher SDS scores were associated with a smaller right parietal cortex (p = .030; r = .542). In the entire sample (both bvFTD and EOAD), higher SDS scores was associated with a smaller lateral ATL volumes (p = .019; r = -.431). Regression analyses confirmed that SDS score predicted lateral ATL volume (p = .041; b = -.262) after controlling for diagnosis (p < .001; b = -.692).
Conclusions:These findings are consistent with greater socioemotional dysfunction, smaller frontal, and larger mesial temporal regions in bvFTD, when compared to EOAD. The findings, however, suggest that positively disturbed socioemotional behavior in bvFTD, as reported by caregivers, results from involvement of the right temporal lobe and the lateral temporal region, with further contribution from disease in OFC. The association of SDS scores and ATL volume across diagnostic groups suggests that this region is instrumental in socioemotional functioning and that the SDS may have diagnostic value in distinguishing the "right-temporal variant" of bvFTD.

Objective:
Previous research has found that trauma is a risk factor for developing early-onset psychosis (EOP), both exhibiting widespread structural abnormalities and social cognitive dysfunction (Hoy et al., 2012; Nair et al., 2020; Rotiker et al., 2018). However, few studies have investigated the association between trauma, neural architecture, and social behaviors. The current study examines whether trauma exposure moderates the association between cortical volume and thickness and social cognition in EOP.
Participants and Methods:T1-weighted whole-brain magnetic resonance data were acquired on a 3T Siemens scanner for 23 adolescents with EOP aged 12-21 years (M = 16.12), and 20 age-matched controls (M = 17.22). Cortical volume and thickness were calculated using the Freesurfer software suite (v5.3; Reuter et al., 2012). Based on prior research, bilateral structures of interest included the rostral anterior cingulate cortex (rACC), insula, precuneus, and superior frontal cortex. Social measures included the WebCNP Emotion Recognition (KER40) and Emotion Differentiation Test (MED36) accuracy score (Gur et al., 2010), The Awareness of Social Inference Test Total Score (TASIT; McDonald et al., 2003), and Social Responsiveness Scale, 2nd Edition (SRS-2; Constantino & Gruber, 2012). Trauma exposure was assessed using the Structured Clinical Interview Diagnostic (controls n = 5; EOP n = 9; First et al., 2015). Pearson’s correlations and independent t-tests were used to examine the relationship between cortical measurements and social cognition. Additionally, PROCESS macro (Hayes, 2018) was used to examine if trauma history statistically moderated the relationship between cortical measurements and social cognition performance.
Results:Significant group differences in SRS-2 scores were observed, as EOP participants scored 24.272 points higher than controls (t = 20.724, p < .001). Across both groups, there was a negative correlation between the SRS-2 score and precuneus volume (r = -.438, p = .011) and thickness (r = -.383, p = .028), TASIT total and superior frontal volume (r = -.349, p = .023), and KER40 and insular volume (r = -.437, p = .20). Further, the moderation analysis revealed that the relationships between precuneus volume and SRS-2 scores, precuneus thickness and MED36 scores, and rACC thickness and KER40 scores depended on experiencing trauma across both groups. Participants with trauma across groups had increased precuneus volume associated with higher SRS-2 scores (p = .0442). Experiencing trauma was also associated with lower precuneus cortical thickness and lower MED36 scores (p = .0172). Conversely, lack of trauma experience was associated with greater rACC thickness and higher KER40 scores (p = .0119).
Conclusions:Our findings indicate that past traumatic experiences may be a moderating factor in the relationship between atypical volume and thickness of social brain regions and social cognition. Overall, the significant interactions between trauma exposure and increased volume and thickness in both EOP and control participants were associated with increased impairment on social cognition measures. These findings emphasize the importance of accounting for the impact of early life adversities on brain development and how it may be relevant to social impairments, especially in individuals experiencing psychosis.

Objective:
Korsakoff's syndrome (KS) is a neuropsychiatric disorder, caused by vitamin B1 insufficiency. KS is characterized by severe declarative amnesia. Often, also executive disorders are present. Emotion recognition and theory of mind are gold-standard measures of social cognition. Moral decision making is often assessed by means of moral dilemmas. Surprisingly social cognition and moral decision making has received hardly any attention in research on KS, although the severity of behavioural problems in KS suggest possible problems in both domains. The aim of this study was therefore to broadly assess social cognition and moral decision-making capacities in patients with KS.
Participants and Methods:20 KS patients and 20 age-, education-, and gender-matched healthy controls were assessed on standardized tests for social cognition, namely the mini-Social Cognition and Emotional Assessment battery (mini-SEA), and a specialized version of the Sally-Anne Test. Moral decision making was assessed by means of the Moral Behaviour Inventory (MBI) for everyday moral dilemmas, and ten cartoons of abstract moral dilemmas. For moral decision making, “yes” and “no” responses were scored, together with a scoring for moral reasoning according to the Kohlberg stages of moral maturity.
Results:KS patients have large impairments in both cognitive and affective aspects of social cognition. Their ability to recognize emotions, take the perspective of others, and understand socially awkward situations is vastly compromised. While KS patients were able to replicate the Sally Anne storyline, their task performance was on chance level. Regarding moral decision making, there was a tendency to more frequently carry out the moral dilemma. Moral maturity, as indexed by means of their reasoning behind the decision was of a lower level. Of interest, moral immaturity could find its origin already before the onset of the KS diagnosis, as suggested by elevated premorbid levels of delinquent behavior.
Conclusions:Both social cognition and moral decision making are compromised in KS patients. Specifically social cognitive disorders are the direct result of KS, and are likely to strongly relate to social and neuropsychiatric issues in KS. Moral decision making was more likely to be already of a lower level of maturity, based on a strong relationship between premorbid delinquency and moral immaturity in KS patients. This study highlights the importance to properly index social cognition in neuropsychological assessments for individuals with a possible KS diagnosis

Objective:
In recent years, rates of alcohol consumption and alcohol use disorder have steadily increased among adults age 60 and older. Large studies have demonstrated that moderate-to-heavy alcohol consumption (>7 drinks per week) is a risk factor for developing various types of dementias. The effects of alcohol-related problems on cognition are less clear, and are particularly understudied in older adults. Similarly, while there is an established link between worse cognition and financial exploitation vulnerability in older adults, no studies have examined relationships between alcohol-related problems and financial exploitation in this population. The current study therefore explores whether alcohol-related problems are associated with neuropsychological performance and financial exploitation vulnerability in a sample of older adults.
Participants and Methods:Participants were a community sample of cognitively unimpaired adults over the age of 50 (N = 55, Age M(SD) = 69.1(6.2), 74.5% female, Years of education M(SD) = 16.8(2.3)). Interested individuals were excluded if they reported current or past substance use disorders. Participants completed a laboratory visit that included a neuropsychological assessment. Measures included the NIH Cognition toolbox, CVLT-II, Digit Span, Trails A/B, Benson Complex Figure Recall, and Verbal Fluency: Phonemic and Semantic, from the Alzheimer’s Disease Centers’ Uniform Data Set (UDS) version 3. Participants completed the CAGE Alcohol Abuse Screening Tool and the Short Michigan Alcohol Screener Test - Geriatric Version (SMAST) to assess alcohol-related problems. Both measures are used as clinical screening tools to measure likelihood of a substance use disorder and produce a summary score (0-4 for CAGE, 010 for SMAST) tabulating symptoms of alcohol-related problems. Participants also completed the Perceived Financial Vulnerability Scale (PFVS) to assess financial exploitation vulnerability. As a significant number of participants reported no drinking and therefore no alcohol-related problems, negative binomial regressions were used to test associations between neuropsychological measures, financial exploitation vulnerability, and alcohol-related problems.
Results:After covarying for age and sex, SMAST was negatively associated with NIH toolbox total cognition (B(SE) = -.14(.07), p<.05) and marginally negatively associated with fluid cognition (B(SE) = -.07(.04), p=.06). Neither SMAST nor CAGE scores were significantly associated with performance on any other neuropsychological test (ps = .13-.99). SMAST was positively associated with financial exploitation vulnerability (B(SE) = .31(.16), p = .05); this effect remained significant after covarying for NIH total composite score in a secondary analysis.
Conclusions:In a community sample of cognitively unimpaired, low-drinking adults over the age of 50, more alcohol-related problems were associated with worse NIH toolbox cognition scores. Similarly, more alcohol-related problems were associated with greater financial exploitation vulnerability, and this relationship was not driven by worse cognition. These results suggest that even low amounts of drinking and alcohol-related problems may be associated with cognition and financial exploitation vulnerability in cognitively unimpaired older adults. This study also corroborates the use of the SMAST over the CAGE in older adult populations that may be more sensitive to cognitive changes.

Objective:
To find how healthy college going participants SRS were affected by a customized Mind Body Intervention (MBI).
Participants and Methods:We performed a customized online tele-video course based MBI incorporating mindfulness and awareness training over a period of one month in 2021 to MBA students attending the Indian Institute of Management (IIM). Each subject was their own control. We used the World Health Organization Quality of Life Scale (QO-BREF) social relationship sub-scores pre and post intervention to assess participant SRS.
Results:277 MBA students from the IIM with a mean age of 26.89 ± 1.7 were analyzed. Of the 277 students, 90 (32.49%) were female. The MBI decreased the self-perceived Social Relationship score among 277 graduate students. The mean SRS before the intervention was 7.51 ± 1.7 while the mean SRS after was 6.9 ± 1.7. Univariate paired t-test showed a significant mean difference (t = 5.1, p<.001). On a multivariate linear-regression model, the SRS change estimate was 0.46, t-value was 9.3, p < 0.001; 95% confidence interval was 0.37 - 0.56; p-value <0.001.
Conclusions:An online tele-video based customized Mind Body Intervention decreased the self-perceived social relationship score among graduate students at the IIM during the Covid-19 pandemic.

Objective:
Persons with behavioral variant frontotemporal dementia (bvFTD) have been shown to exhibit altered morality, manifested as atypical utilitarian tendencies towards sacrificial moral dilemmas. This takes the form of endorsing harmful actions towards single individuals, including vulnerable or relationally close individuals (e.g. children, loved ones), in order to promote the greater good for the community or society as a whole. The dual process model of moral cognition interprets such tendencies as deriving from a lack of emotional engagement, whereas moral emotion theory views them as selective impairment in prosocial sentiments. We hypothesized that both the widespread neuropsychological practice of using sacrificial moral dilemmas to evaluate moral reasoning, and these tests' overreliance on quantitative results, inadequately represent how persons with bvFTD reason and feel while responding to moral dilemmas. To evaluate this hypothesis, we applied a mixed-methods approach to identify the reasoning, motivations, and emotional experiences of bvFTD persons during their deliberation about moral scenarios.
Participants and Methods:We conducted semi-structured interviews with 14 participants: 7 persons with bvFTD & 7 older healthy controls. Transcripts were coded in Atlas 5.0 to characterize the underlying reasoning, emotions, response processes, and values that emerged when responding to a structured set of moral dilemmas. Our dilemmas measured utilitarian reasoning holistically by incorporating both sacrificial and impartial/altruistic components, as suggested by the 2-dimensional model of utilitarianism.
Results:Unexpectedly, bvFTD persons articulated a prosocial compass when asked about their values, stating they were organizing their choices predominantly around kindness and altruism, even when they were making choices to harm loved ones or vulnerable individuals to promote the greater good. During moral deliberation, persons with bvFTD showed significantly less metacognition (bvFTD = 10%, HC = 90%) but reported more positive emotions (joy; bvFTD = 83%, HC = 17%) than negative (frustration; bvFTD = 30 %, HC = 70 %) compared to controls. Qualitatively, this observed emotional outlook was typically coupled with a more rigid, simplistic viewpoint (e.g., "I felt great, it was a no brainer"), suggesting a moral understanding lacking emotional nuance and complexity.
Conclusions:Our data showed that bvFTD persons' utilitarian responses to moral dilemmas did not arise from an emotionally flat or antisocial cognitive perspective, but instead were guided by positive emotionality, simplistic reasoning, and prosocial values. These findings challenge the current understanding of the reasoning processes and experiences of persons with bvFTD and highlight the importance of incorporating mixed method approaches in dementia research that take into consideration the viewpoint of the cognitively compromised individual.

Objective:
Previous research suggests that individuals with isolated Agenesis of the Corpus Callosum (AgCC) have cognitive and psychosocial deficiencies that include impaired recognition of the emotions of others (Symington et al., 2010) and a diminished ability to infer and describe the emotions of others (Paul et al., 2021; Turk et al., 2010). In addition, galvanic skin responses effectively discriminated between emotional images despite atypical emotion ratings (Paul et al, 2006), supporting a dissociation between cognitive and affective empathy in AgCC. Likewise, atypical patterns of visual attention to faces corresponded with impaired emotion recognition in AgCC (Bridgman et al, 2014), suggesting that atypical visual attention in AgCC negatively impacts the ability to identify others’ emotions. This study used the Multifaceted Empathy Test [MET] (Foell et al., 2018) to examine the impact of visual aesthetics (photo composition) on empathetic feelings (affective empathy) and situational emotion recognition (cognitive empathy) in persons with AgCC. Both cognitive and affective empathy scores are typically higher on MET stimuli composed according to the “Golden Spiral” (Callaway, 2022).
Participants and Methods:Results from 50 control participants recruited from Cloud Research were compared to responses from 19 participants with AgCC and normal-range FSIQ (>80). Data was gathered through an online version of the MET, which uses a series of photographs of individuals displaying an emotion, half of which adhere to the compositional technique known as “The Golden Spiral.” To measure cognitive empathy, the participants are asked to pick the correct emotion being displayed with three distractors for each item. To measure affective empathy, they are then asked on a sliding scale, “how much do you empathize with the person shown” (1 = Not at all, 7 = Very much).
Results:Repeated measures mixed ANOVAs revealed no difference between AgCC and control groups on affective empathy, and as expected on the MET, both groups had significantly higher ratings for photos composed according to the Golden Spiral (AgCC, np2 = .071; control, np2 = .136). In contrast, the AgCC group scored significantly lower than controls overall on cognitive empathy, np2 =.065. Exploratory post-hoc found a significant group difference in cognitive empathy only on photos composed according to the Golden Spiral, np2 = .090, with the scores in the AgCC group unimpacted by composition type while the control group exhibiting significantly higher scores Golden Spiral images, np2 = .254.
Conclusions:Empathic deficits in AgCC were restricted to the cognitive component, while affective empathy was not impaired. Visual aesthetics of photo composition influenced affective empathy ratings in both AgCC and control groups. However, adults with AgCC had diminished ability to give cognitive labels to the emotional states of others, which was not enhanced by the formal aesthetics of stimuli. Thus the corpus callosum seems to facilitate the ability to cognitively label emotions by facilitating visual attention. It also suggests that the corpus callosum does not facilitate affective empathy, in part because it does not appear to determine whether formal aesthetics influences the processing of visual stimuli in AgCC or neurotypical controls.

Objective:
Previous studies have demonstrated a high prevalence of social and emotional problems in young adults with a history of childhood epilepsy, with social skill impairment hypothesized to play a significant role in these outcomes. Few studies have examined social skills within children with epilepsy and very few have examined this within the context of other neuropsychological and neurological variables. This study aims to examine the association between social problems and other relevant neuropsychological variables (IQ, adaptive functioning, social skills) within the pediatric epilepsy population.
Participants and Methods:Participants were 86 epilepsy patients between the ages 5 and 18 years of age who were referred for neuropsychological assessment as a part of their surgical candidacy work-up. Pearson correlation analysis was conducted to examine the correlations between performance on objective measures of full-scale IQ, and parent ratings on questionnaires assessing parent perception of the patients’ overall adaptive functioning, social skills, and social problems.
Results:As expected, earlier age of onset was associated with lower IQ, which itself was associated with weaker overall daily living skills and social skills. Later age of seizure onset was associated greater social problems. Social skills were not correlated with social problems.
Conclusions:The results of this study suggest that children with later age of onset of seizures, are at increased risk of social problems and that these problems may not related to social skill impairment. Implications for clinical practice and future directions are discussed.

Objective:
Theory suggests that symptoms of Attention-deficit Hyperactivity Disorder (ADHD; e.g., hyperactivity and impulsivity) may be associated with social cognition deficits characterised by fast but erroneous processing of social cues. Despite this, prior research has provided mixed evidence for (a) deficits in social cognition skills and (b) a link between such deficits and poor social outcomes among children with ADHD. We sought to clarify this ambiguity by (a) exploring variation in social cognition skills across a mixed clinical and normative population and (b) examining the demographic, clinical, and dimensional symptom profiles of children presenting with reduced social cognition skills characterised by fast but erroneous processing.
Participants and Methods:Participants were children and adolescents (N = 1,097) aged 4–18 years (M = 9.02, SD = 2.72) assessed using the Paediatric Evaluation of Emotions Relationships and Socialisation (PEERS), a child-direct, ecologically sensitive measure of social cognition. Latent profile analysis of standardised social cognition scores and response times for incorrect encoding of social cues (error-response times) was used to identify social cognition profiles. Differences between each profile in terms of demographics, clinical profiles, symptom dimensions, and social outcomes were explored.
Results:Four social cognition profiles were identified. Two profiles were identified as being of particular interest: one which captured typically developing children (TDC; n = 727), and another which was characterised by lower social cognition scores and faster error-response times (impulsive responding; n = 201). The remaining profiles captured the response styles of younger participants (n = 152) and children with more pervasive social cognition deficits (n = 17). Comparison of the two profiles of interest revealed a number of statistically significant differences (p < .05). Compared to the TDC group, the impulsive responding group had: higher SDQ scores for hyperactivity, conduct, emotional, and peer problems; lower IQ and prosocial scores, and; greater parent-perceived social function deficits. Children in this group were also more likely to be male and from a lower SES background. Clinically, 18% of children in the impulsive responding group had an ADHD diagnosis, and 14% had at lease one mental health diagnosis other than ADHD.
Conclusions:A large minority of children (~18%) demonstrate social cognition deficits characterised by fast but erroneous processing of social cues. Although the explorative nature of this study does not allow conclusions to be made about the causes of such deficits, it is reasonable to conclude that they are not reducible to clinically significant symptoms of hyperactivity-impulsivity — less than 1/5 of the children in this group had an ADHD diagnosis, and 2/3 of children in this group had no mental health diagnosis at all. Child-direct tools designed to detect individual differences in social cognition skills may be beneficial in identifying individuals who will benefit from social support or interventions aimed at reducing social cognition deficits despite being missed by more traditional screening measures (e.g., clinical diagnoses). Future work should focus on understanding the causal relationships between symptoms of hyperactivity-impulsivity, fast but erroneous processing of social cues, social cognition skills, and social outcomes for this group of children.

Objective:
Hemispherectomy (HE) is a surgical intervention to treat intractable epilepsy. It involves disconnecting or removing the right or left cerebral hemisphere, depending on the location of the pathological substrate or epileptogenic activity. HE impacts neural functions related to social cognition (Fournier et al., 2008). This study investigates the effects of childhood HE on social deception and sarcasm using the Thames Awareness of Social Inferences Task (TASIT; McDonald, Flanagan, & Rollins, 2010) to explore emotion identification and social inference appraisal as adults.
Participants and Methods:Fifteen adults with hemispherectomy and 16 neurotypical controls completed the TASIT. All HE patients underwent hemispherectomy (right-HE = 10) during childhood (age of surgery = 3 months to 16 years) and had FSIQ > 70 at the time of study. HE and control groups were matched for age (HE M = 25.7, SD = 5.4; control M = 27.1, SD = 10.7) and education (HE M = 14.0, SD = 1.88; control M = 13.3, SD = 1.8). FSIQ was significantly lower in the HE group than control group (HE M= 90.8, SD = 9.4; control (M = 100.4, SD = 7.1). TASIT uses videotaped vignettes to assess aspects of social perception: emotion recognition (Part 1), social inference regarding sincerity, simple sarcasm, and paradoxical sarcasm (Part 2) and social inference regarding sincerity of speech (lie vs sarcasm) in the presence of additional text or visual cues (Part 3).
Results:For Part 1, MANCOVA (covarying FSIQ) found no group difference in emotion identification. Analysis of data from Part 2 was conducted using repeated measures ANCOVA accounting for 2 groups x 3 conditions (sincere, simple sarcasm, and paradoxical sarcasm) and revealed only a significant overall group effect, F (1, 28) = 5.72, p = .024, np2 = .170. Likewise, analysis of Part 3 using repeated measures ANCOVA accounting for 2 groups x 2 cue types (visual, text) and 2 actor intentions (lie, sarcasm) revealed only a significant overall group effect, F (1,28) = 11.35, p = .002, np2 = .288, with no interaction of group by condition.
Conclusions:HE patients exhibited no difficulty identifying basic emotional expressions. Performance was significantly impaired when additional social information was added to the context (i.e., detecting sarcasm or deception). HE patients begin to struggle with the complexity of new social information or how it changes the meaning of a conversation. Even simple sarcastic exchanges are difficult to interpret. When a visual or textual cue was introduced to reveal the true state of affairs, HE patients could not could integrate the information into their interpretations of the scenario. There are unique contributions of the left and right hemispheres to cognitive processes for complex social behavior, and absence of an entire hemisphere results in deficits in social language comprehension. Future research should investigate performance differences in left vs. right HE patients.

Objective:
During the COVID-19 pandemic, wearing face masks is an important strategy to prevent people from infection, allowing people to find a balance between maintaining social interaction and keeping social distancing. Since face mask might disrupt information processing of social cognition, it could lead to less functional connectivity of occipital face area, fusiform face area, and superior temporal sulcus which interrupted the development of medial prefrontal cortex (MPFC) for mentalizing. However with better executive function (EF) people could process facial stimuli more efficiently. The objective of this study is to examine the effect of wearing face masks on preschoolers' facial emotion recognition, and the factors which might affect the development of facial emotion recognition.
Participants and Methods:In this study, preschoolers (N=44, 24 boys and 20 girls, aged 3 to 5 years-old) recruited from the community were asked to identify the emotions expressed in the 36 stimulus photos, each randomly presented with six emotion (happy, sad, angry, surprised, fearful, and disgusted). The total face stimulus photos were 2 (face sex) × 6 emotions × 3 facial features (full face, presenting upper counterparts of face with face mask covering the mouth, and presenting lower counterparts of face with hat covering the eyes). The EF of preschoolers and their parent were also evaluated to examine whether EF could predict the correct score of facial emotion recognition.
Results:It was found that the correct score of emotion recognition increased with age. The recognition with full face feature were better than with upper feature and lower feature. When recognizing happy and disgust, participant tended to use lower features. When recognizing sad and angry, participant tended to use upper features. The EF of preschoolers could predict the correct score of emotion recognition. The EF of parents could predict the preschoolers' correct score of positive emotion recognition.
Conclusions:The ability of facial emotion recognition evolved rapidly in preschool age with the accumulation of social interaction experience and improved the development of auditory and visual subcortical cortex and the connectivity of MPFC. This study examined the emotion recognition ability of preschoolers and found that the face features preschoolers used to recognized emotion were consist with previous study. However, when the presenting stimulus were covered by face mask or hat, it was more difficult for preschoolers to recognizing emotion which would result in difficulty of understanding the social context and development of MPFC for mentalizing. In this study, it was found that preschooler's with better EF could be more efficiently recognizing facial emotion. Also, parents with better EF showed more positive emotion in daily life which lead to their children more sensitive to positive facial emotion.

Objective:
Social cognition refers to processing, analyzing and understanding information about emotions and social situations. Many studies indicate a frequent deficit of these functions in people with tumors of the cerebellum. Visual search is an important attention process prior to information processing. It also mediates the relationship between cognitive function (attention) and social cognition. There are numerous data showing that disorders of various aspects of attention are fairly common in patients with tumors of the cerebellum. The question arises whether there is any relationship between these functions. The purpose of this study was to find out if there is a relationship between visual search performance and the ability to recognize emotions.
Participants and Methods:The study included 19 patients with the cerebello-pontine angle (CPA) tumors (mean age = 38.84, SD = 14.27; 10 women and 9 men) and 19 healthy controls (mean age 38.26, SD = 10.40; 10 women and 9 men). The research group consisted of patients from the Department of Neurosurgery, UCK Medical University of Warsaw, the control group was healthy. The groups did not differ demographically. At the beginning, the respondents completed a questionnaire in which they were asked about demographic data and health status. Then, a series of 40 boards presenting the letters T in two colors, blue and orange, scattered in different planes was presented. The letters were right or upside down. The test person’s task was to find and click the correctly positioned orange T letter as quickly as possible. Then, a series of 56 photos of faces representing seven different emotions was presented (happiness, anger, sadness, surprise, disgust, fear and a neutral face). The test person’s task was to decide which of the emotions mentioned under the photo were presented by the presented face.
Results:The results indicated that patients with tumors in the CPA area had a longer mean reaction time and lower accuracy when performing visual searches than subjects from the control group. Likewise, there were longer times and lower accuracy in the emotional recognition task. Moreover, in the group of patients with CPA tumor, the response time during visual search was negatively associated with the correctness of the response in visual search (p = -0.57, p <0.05). There were also negative correlations between the reaction time and the correctness of recognizing particular emotional states: anger (p = -0.48, p <0.05), disgust (p = -0.62, p <0.01) and neutral (p = -0.64, p <0.01). The correctness of answers in visual search correlated positively with the accuracy of emotion recognition (p = 0.72, p <0.01). None of the above-mentioned relationships were found in the control group.
Conclusions:The obtained results indicate a relationship between the quality of visual attention and the ability to recognize emotions in people with cerebellar lesions. In order to better understand this phenomenon, it is necessary to continue research in this field.

Objective:
Combat exposure is associated with higher rates of depressive symptoms, including anhedonia (i.e., a reduced ability to seek and experience rewards) and feelings of social disconnectedness. While these symptoms are commonly documented in combat-exposed Veterans following deployment, the cognitive mechanisms underlying this pathology is less well understood. Computational modeling can provides detailed mechanistic insights into complex cognition, which may be particularly useful to understand how social reward processing is altered following combat exposure. Here, we use a Bayesian learning model framework to address this question.
Participants and Methods:Thirty-three Operation Enduring Freedom (OEF)/ Operation Iraqi Freedom (OIF)/Operation New Dawn (OND) Veterans (25 Male, 8 Female) between the ages of 18-65 years old (M = 41.61, SD = 10.49) participated in this study. In both classic/monetary and social reward conditions, participants completed a 2-arm bandit task, in which they must choose on each trial between two options (i.e., slot machine vs social partner) with unknown reward rates. While they received monetary outcomes in the classic condition, participants received compliments from different fictitious partners in the social condition. We first compared a learning-independent Win-stay/Lose-shift (WSLS) heuristic and either a Rescorla-Wagner Q-learning or a Bayesian learning model (Dynamic Belief Model/DBM) paired with a Softmax reward maximization policy. DBM+Softmax provided the best fit of the data for most participants (31/33). Individual DBM parameters of prior reward expectation, reward learning (i.e., perceived stability of reward rates), and Softmax reward maximization were estimated and compared across conditions.
Results:Participants did not differ in their reward learning parameters across monetary and social conditions (t(30)= -0.70, p = 0.490), suggesting similar perception of reward stability in both modalities. However, higher Bayesian prior mean (i.e., initial belief of reward rate; t(30)= -2.31, p = 0.028, d=0.42) and greater reward maximization (i.e., Softmax parameter; t(30)= -2.26, p = 0.031, d=0.41) were observed in response to social vs monetary rewards. In the social reward condition, higher self-reported social connectedness was associated with greater model fit of our DBM model (i.e., smaller Bayesian Information Criterion/BIC; r = -0.38, p = 0.041). In this condition, those expecting higher reward rates when initiating reward exploration (those with higher DBM prior mean) endorsed lower self-esteem (Spearman's ρ = -0.43, p = 0.078) and lower positive affect (ρ = -0.32, p = 0.078).
Conclusions:A Bayesian learning modeling framework can characterize mechanistic differences in the processing of social vs non-social reward among combat-exposed Veterans. Individuals with higher social connectedness were more model-based in their performance, consistent with the notion that they are more likely to estimate and anticipate how much social peers have to offer. Combat-exposed individuals with lower self-esteem and positive affect appear to have higher initial expectations of reward from unknown partners, which could reflect greater need for mood and/or self-esteem repair in those individuals. Overall, Bayesian modeling of social reward behavior provides a useful quantitative framework to predict clinically relevant construct of functional outcomes in military populations.
