We combined behavioral measures and event-related potentials (ERPs) to examine how feedback attributed to an AI or human counterpart influenced risky decision revision under alignment and misalignment. Participants completed a two-stage risky decision task: they first chose between a risky and a safe option, then viewed an aligned or misaligned choice attributed to either an AI or a human counterpart, and finally made a revised choice. Switching rates and attitudes toward AI were measured, and ERPs were time-locked to feedback onset. Behaviorally, participants switched more when misaligned with AI than with a human, and higher AI acceptance predicted greater switching under AI misalignment. Neurally, the N1 was more negative for human- than AI-attributed feedback, suggesting early differentiation of counterpart identity. The FRN was more negative for misalignment than alignment, with no counterpart effect. The P3 was larger for alignment than misalignment and larger for AI than human under alignment, and increased with more positive AI attitudes. These findings suggest stage-differentiated processing of AI- and human-attributed social feedback during risky decision revision.","PeriodicalId":94208,"journal":{"name":"Social cognitive and affective neuroscience","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13215087/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147848247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite its significant impact on functional outcomes, quality of life, and caregiver burden, the neural mechanisms underlying apathy remain poorly understood. Static and dynamic functional connectivity serve as neural fingerprints for personalized predictions, capturing complementary aspects of brain function and engaging distinct networks. This study developed predictive models of apathy using both static and dynamic functional connectivity to elucidate network-level mechanisms in healthy university students. Static connectome-based predictive modeling (CPM) demonstrated that disrupting the default mode network significantly impaired prediction, which may be related to deficits in internal motivation associated with apathy. Dynamic CPM revealed that lesioning the medial frontal, fronto-parietal, and visual II networks diminished accuracy, suggesting that impairments in behavioral initiation and execution in apathy. By integrating static and dynamic connectivity in predictive models, this study uncovers complementary network dynamics underlying apathy and highlights the potential neural basis of apathy.","PeriodicalId":94208,"journal":{"name":"Social cognitive and affective neuroscience","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13191324/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147483191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study combined EEG microstate and spectral analyses to investigate empathy-related neural processes in 71 typically developing preschoolers (aged 3-6 years) during naturalistic viewing of socioemotional animations. Spectral analysis revealed increased occipital theta, centrotemporal alpha, and temporal beta activities during empathy-eliciting clips compared to baseline. Theta activity in response to Theory of Mind (ToM) clips negatively correlated with children's negative emotion understanding, while alpha activity during Emotional Contagion (EC) clips positively correlated with positive emotion resonance. Age-related decreases in occipital theta power and increases in centrotemporal alpha power were observed, paralleling behavioral improvements in prosocial helping behavior. Microstate analysis identified hierarchical age-related shifts: reduced coverage of microstate MS5 and increased transitions from MS5 to MS2 during ToM processing, implying that as children mature, perspective-taking efficiency increases, redirecting neural resources to response preparation. These findings suggest an age-related neural cascade framework where perceptual efficiency gains may free cognitive resources for mentalizing and emotion regulation, enabling more advanced prosocial actions. The present work suggests that EEG spectral and microstate metrics serve as sensitive neurophysiological indices for assessing early childhood age-related changes in empathy within naturalistic contexts.","PeriodicalId":94208,"journal":{"name":"Social cognitive and affective neuroscience","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13275308/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148166095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because child abuse is transmitted through social interactions, developing effective intervention targets to disrupt these cycles may require understanding the mechanisms that support processing social feedback. This study examines whether neural biases in processing positive or negative social feedback moderate the link between history of childhood abuse and current expression of harsh parenting. Using fMRI and well-matched social and monetary feedback tasks, we studied female caregivers (N = 56; 46.16 ± 7.49 years) of adolescents. In the social feedback task, activation to negative relative to positive feedback in the anterior hippocampus, putamen, amygdala, dorsal anterior cingulate cortex (dACC), posterior cingulate cortex (PCC), and medial prefrontal cortex (mPFC) moderated the link between childhood abuse and harsh parenting. Specifically, abuse severity was most strongly associated with harsh parenting among individuals with greater activation to negative relative to positive feedback. No comparable effects emerged from the monetary task. These findings suggest sensitivity to social feedback, and negative feedback in particular-may promote risk for intergenerational abuse transmission.","PeriodicalId":94208,"journal":{"name":"Social cognitive and affective neuroscience","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13600677/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148908279","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we investigated how the representation of social perceptions (trustworthiness and likeability ratings) and bodily responses [skin conductance response (SCR)] are modulated by prediction strength, using representational similarity analysis. In two samples of university students, stronger predictions led participants to judge identities as more trustworthy and likeable when identities' facial reactions conformed to their predictions compared to when they were violated. Furthermore, the representational structure of social judgments and SCR were associated with models of prediction fulfillment/violation. More importantly, the similarity between social judgments, SCR representations, and models of prediction violation was positively linked to predictions strength. These results demonstrate that predictions strength modulates how fulfilled/violated predictions influence social judgments and bodily responses, providing new insights into the mechanisms underlying social perception.","PeriodicalId":94208,"journal":{"name":"Social cognitive and affective neuroscience","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13242948/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147583387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It remains unknown whether exclusion selectively alters social (vs. monetary) reward processing via hypervigilance or compensatory affiliation mechanisms. To address this, we recruited 61 participants to complete a Cyberball-based social exclusion or inclusion induction, with an electroencephalogram recorded during subsequent social and monetary reward tasks. Results revealed that positive versus negative feedback elicited stronger reward positivity in the social inclusion condition, while such an effect was eliminated by social exclusion. However, this interaction effect was absent for P300 during the consummatory stage or the stimulus preceding negativity during the anticipation stage. Meanwhile, social exclusion reduced the delta power, enhanced positive social evaluations, and led to a dissociation between this positive evaluation and the delta power in response to others' social feedback. In contrast, for monetary reward processing, no effects of social exclusion were found. This domain-specific effect was further validated by cross-task comparison. These results suggest that social exclusion selectively attenuates the initial cognitive processing of social rewards, disrupts the association between neural feedback and behavior, and may trigger a dual coping mechanism involving withdrawal self-protective neuroadaptations, and approach-driven prosocial behavioral tendencies.","PeriodicalId":94208,"journal":{"name":"Social cognitive and affective neuroscience","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13120880/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147483193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using functional near-infrared spectroscopy hyperscanning, 33 parent-child dyads (children 8-15 years) played a tablet-based game (\"The Flocking Game\") under spontaneous and intentional synchrony instructions. Results revealed that dyads exhibited behavioral synchrony values significantly greater than zero (with zero reflecting no synchrony) even without instruction, and synchrony increased when coordination of movement was explicitly required. Parents led more during spontaneous play, reflecting their natural regulatory role, whereas leadership equalized under intentional instructions. Neural analyses revealed significant inter-brain synchrony across the dorsolateral prefrontal cortex (DLPFC), inferior frontal gyrus (IFG), and inferior parietal lobule (IPL). In the intentional condition, stronger parent left-DLPFC coupling with the child IFG or IPL predicted greater behavioral synchrony, while spontaneous synchrony was linked to parent IPL-child IFG synchrony. These results suggest that spontaneous synchrony relies on mirroring within the action observation network, whereas intentional synchrony engages executive control, highlighting complementary neural pathways through which parental leadership shapes goal-directed interaction.","PeriodicalId":94208,"journal":{"name":"Social cognitive and affective neuroscience","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13509953/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148698752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
