While acting in parallel involves agents pursuing individual goals, acting jointly requires them to share a collective goal. We used dual EEG to investigate neural dynamics underlying these action types. We recorded event-related potentials (ERPs) from 20 dyads while they had to transport an object in a video game, either jointly or in parallel. Conditions were matched for task execution complexity, confirmed by equal success rates. Results revealed a distinctive pattern swap in ERPs during action preparation. Early preparation showed significantly higher amplitude during joint versus parallel action. This pattern reversed in late preparation, with significantly reduced ERP amplitude in joint compared to parallel action. Notably, decreased late ERPs correlated with higher RT variability in partners but not participants' own RT variability. This dynamic swap suggests different cognitive processes operate at distinct stages of action preparation. Sharing a collective goal may impose cognitive costs (reflected in higher early ERPs), but this is offset by facilitated late action preparation (as shown by reduced late ERPs), likely due to the enhanced predictability of partners' actions.","PeriodicalId":94208,"journal":{"name":"Social cognitive and affective neuroscience","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144710419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Grounded cognition theories propose that such social concepts are represented in brain circuits involved in processing social interactions. The present event-related potential study investigated the time course of electrical brain activity in response to abstract social concepts compared to abstract control concepts presented during a lexical decision task. Analysis of estimated volume source activity revealed increased activity to social concepts in the left insula with an onset of 216 ms and somewhat later in frontal brain areas (292 ms). These regions are associated with empathy and mentalizing, respectively. Social concepts also enhanced activity in the left anterior temporal lobe (292 ms), a heteromodal semantic hub supporting semantic integration. Later (438 ms), social concepts activated a fronto-parietal brain network typically engaged during social interaction. Early activity increases in social cognition brain networks (< 300 ms) most probably indicate access to conceptual features, while later activity increases may reflect semantic elaboration. In accordance with hybrid models of conceptual cognition, processing of abstract social concepts is grounded in brain regions associated with empathy and social interactions, complemented by semantic integration processes in heteromodal semantic hub areas.","PeriodicalId":94208,"journal":{"name":"Social cognitive and affective neuroscience","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144700793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is perhaps most relevant for event-based, or thematic, knowledge and social knowledge which is acquired through social experiences. The present study investigated neural specialisation for social concepts by examining whether distinct semantic regions or hubs represent taxonomic versus thematic relations and social versus non-social relations. Specialization was examined in two groups with different social experiences: autistic and non-autistic adults. There were minimal behavioural and no neural differences between groups, suggesting that differences in social experiences between autistic and non-autistic people may be better understood at the interactional level. In whole-brain analyses across both groups, taxonomic relations engaged the semantic control network to a greater extent than thematic relations did, and n overlapping portion of the rostroventral area of left angular gyrus was engaged by both thematic (relative to taxonomic) and social (relative to non-social) relations. Region of interest analyses revealed a more complex pattern within bilateral angular gyri. The results suggest that angular gyrus represents conceptual knowledge in a graded fashion, including specialisation for thematic and social relations.","PeriodicalId":94208,"journal":{"name":"Social cognitive and affective neuroscience","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144700792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the neural mechanisms underlying this process in young children remain underexplored due to challenges in neuroimaging this population. Optically pumped magnetometers (OPMs), a wearable magnetoencephalography (MEG) technology, offer potential advantages for studying these responses early in life. This study investigated evoked responses and functional connectivity in 45 children (3-5 years) during an emotional face processing task using OPM-MEG. The M170 component, a key marker of face processing, and whole-brain functional connectivity of eight regions of interest were assessed. Children exhibited a robust M170 response to emotional faces in the bilateral fusiform gyri. Peak amplitude increased with age, but no significant latency changes were observed. A significant network of increased connectivity following emotional face onset, involving connections between the amygdalae, insulae, occipital, and frontal regions was found. This study provides the first evidence of M170 responses and large-scale connectivity to emotional faces in young children using OPM-MEG. Findings highlight the feasibility of OPMs for developmental neuroimaging and provide insights into the maturation of emotion-related neural circuits in early childhood. These results establish a foundation for future face processing research in clinical paediatric populations, such as autism.","PeriodicalId":94208,"journal":{"name":"Social cognitive and affective neuroscience","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144710420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditionally, researchers have examined how the brain supports mentalizing. Here, we ask what content knowledge the brain relies on to mentalize. Based on converging evidence from developmental, cognitive, and social-affective neurosciences, we suggest that the socio-affective knowledge gained from early attachment relationships provide the basis for such content knowledge. Moreover, we suggest that this attachment relationship-generated schematized knowledge is represented in the medial prefrontal cortex (mPFC) and accessed during mentalizing. In this paper, we (1) describe mPFC activity during early caregiving experiences to demonstrate its encoding of the affective meaning of parent-child interaction episodes; (2) extrapolate from research on memory consolidation in the cognitive neurosciences to propose how regularities across parent-child interactions become abstracted into an attachment schema in the mPFC; (3) discuss the functionality of mPFC-coordinated representations of attachment schemas for predicting the social world. Long recognized by attachment theory, our integrative perspective prompts researchers to neuroscientifically examine whether the social relationship with one's caregiver builds attachment knowledge that in turns forms the basis for mentalizing.","PeriodicalId":94208,"journal":{"name":"Social cognitive and affective neuroscience","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144683914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, despite these technological achievements, public acceptance and valuation of AI-generated creative products remain uncertain. This study investigates the bias against AI-generated artworks by examining both behavioral and neural responses using electroencephalography (EEG) and functional near-infrared spectroscopy (fNIRS). Across two pre-registered studies (total N = 125), participants evaluated paintings labeled as either human-created or AI-generated, with the artworks being objectively identical. Behavioral results revealed a consistent bias against AI-labeled paintings, with participants rating them lower in different evaluative dimensions. Neural data from EEG indicated relatively higher P300 amplitudes and alpha power during the evaluation of human-labeled paintings, suggesting potentially greater attentional allocation and cognitive engagement. The fNIRS results further demonstrated increased activity in the right angular gyrus and stronger functional connectivity between the inferior frontal gyrus and angular gyrus for human-labeled artworks, which may indicate deeper semantic and emotional processing. These findings highlight that biases against AI-generated artworks are not only evident in explicit evaluations but also manifest in underlying neural processes, reflecting a persistent preference for human creativity. The study underscores the importance of addressing public biases to foster acceptance and trust in AI technologies.","PeriodicalId":94208,"journal":{"name":"Social cognitive and affective neuroscience","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144612739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using hyperscanning fNIRS and dyadic behavioral analysis, data from 72 dyads (36 romantic couples and 36 friends) were analyzed. Results revealed an intimacy-by-modality interaction: couples showed better behavioral coordination and higher interpersonal neural synchrony (INS) in the 0.081-0.09 Hz band during FTF, while friends had better synchrony in VMC. In the 0.038-0.046 Hz band, friends exhibited greater INS during FTF, and couples showed better synchrony in VMC. These patterns suggest that high-frequency INS is associated with real-time social cue integration, while low-frequency INS relates to ongoing relational monitoring. Verbal behavior fully mediated the relationship between satisfaction and FTF-induced prefrontal INS, highlighting connections among psychological states, behavior, and neural alignment. Granger causality analysis showed a female-to-male neural influence during FTF, absent in VMC, likely due to reduced nonverbal signals. These results demonstrate that the influence of video mediation on interpersonal synchrony is relationship-specific and frequency-dependent, empirically supporting a relational-context model that links attachment-based sensorimotor tuning with channel-selection processes in the Communicative Interdependence Perspective.","PeriodicalId":94208,"journal":{"name":"Social cognitive and affective neuroscience","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144602702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to studies in attachment, individual differences in attachment anxiety and avoidance may lead to difficulties in the strategies used to regulate emotions. These dispositions may shape the neural mechanisms underlying regulation. This study examined oscillatory brain connectivity during two strategies-cognitive reappraisal and expressive suppression-across delta (1-3 Hz), theta (4-8 Hz), alpha (9-12 Hz), and beta (15-30 Hz) bands. We also tested whether attachment orientations modulate these connectivity patterns. Sixty adults completed an emotion regulation task while EEG was recorded. Connectivity was estimated using the debiased weighted Phase Lag Index (wPLI). Linear mixed-effects models assessed the effects of condition, attachment, and their interaction on connectivity between frontal or central electrodes and the rest of the scalp. Reappraisal increased theta-band connectivity between frontal and distributed sites, while suppression enhanced beta connectivity involving frontal and central electrodes. Higher attachment anxiety was associated with reduced theta connectivity during reappraisal, and higher avoidance predicted increased beta connectivity during suppression. These findings suggest that emotion regulation strategies engage distinct oscillatory networks, modulated by interpersonal dispositions. Theta connectivity may reflect top-down control processes in reappraisal, while beta connectivity may support inhibition during suppression.","PeriodicalId":94208,"journal":{"name":"Social cognitive and affective neuroscience","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144546731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

How do features of people's real-world social networks relate to responses to social exclusion? People central in social networks-e.g., who have many friends-may be less distressed by exclusion, since they have many sources of support, or more sensitive to it, if they are more attuned to social feedback. We characterized a village's social network; a subset of residents (N = 74) completed an fMRI study involving social exclusion in groups characterized by varying social relationships (spouses, friends, strangers). Highly-central individuals reported greater distress during exclusion by strangers, and their distress ratings scaled with responses in brain regions associated with social pain, negative affect, and mentalizing. Thus, while social connectedness is often considered a protective factor that promotes well-being, these findings suggest a potential ironic effect of social connectedness-vulnerability to distress in particular social contexts. This sensitization to exclusion could constitute an adaptive tendency to promote long-term wellness.","PeriodicalId":94208,"journal":{"name":"Social cognitive and affective neuroscience","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144532176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
