However, the underlying neural mechanisms remain unclear. This electroencephalography study investigated whether the interactive exchange of facial expressions modulates socio-emotional processing. Participants (N = 41) displayed a facial emotional expression (angry, neutral, or happy) toward a virtual agent, and the agent then responded with a further emotional expression (angry or happy) or remained neutral (control condition). We assessed subjective experience (valence, arousal), facial EMG (Zygomaticus, Corrugator), and event-related potentials (EPN, LPP) elicited by the agent's response. Replicating previous findings, we found that an agent's happy facial expression was experienced as more pleasant and elicited increased Zygomaticus activity when participants had initiated the interaction with a happy compared to an angry expression. At the neural level, angry expressions resulted in a greater LPP than happy expressions, but only when participants directed an angry or happy, but not a neutral, expression at the agent. These findings suggest that sending an emotional expression increases salience and enhances the processing of received emotional expressions, indicating that an interactive setting alters brain responses to social stimuli.","PeriodicalId":94208,"journal":{"name":"Social cognitive and affective neuroscience","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11781275/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143019280","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}

The aim of this study was to investigate the neural and cognitive mechanisms involved in generating the sense of agency in such a joint action context. Two players (a participant and a confederate) jointly moved a Ouija board-style planchette containing a wireless mouse. This, in turn, moved a digital board on the screen. Participants reported a greater sense of agency in the condition where they had complete control of the planchette (the 'self' condition), and least agency when they passively held the planchette while it was moved by the confederate ('other' condition), with the two 'joint' action conditions in between. While the N1 peak did not differ between conditions, the early part of the N1 differentiated between the joint action conditions, and the solo action conditions. In contrast, the Tb and P2 components differed between the 'other' condition and the 'self' and 'joint' conditions. These findings are discussed with reference to motor-prediction and attentional mechanisms.","PeriodicalId":94208,"journal":{"name":"Social cognitive and affective neuroscience","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11776751/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143019277","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}

By adopting the premovement facilitation paradigm, we applied transcranial magnetic stimulation over the left or right primary motor cortex at rest and 100 ms or 50 ms before movement onset while healthy volunteers performed a reaction time (RT) motor task consisting of abductions of the right or left thumb after a go signal. Participants in the placebo group received an inert electrical device applied on the right forearm along with information on its speed-enhancing properties. A control group received the same device with overt information about its inert nature, while another control group underwent no intervention. Along with RT, we measured the amplitude of the motor evoked potential (MEP) before and after the procedure. Compared to the control groups, the placebo group had faster RT and greater MEP amplitude before movement initiation. This study demonstrates that the placebo effect can boost the activity of the corticospinal tract before movement onset, and this modulation positively impacts motor performance. These results give experimental support to the active inference account.","PeriodicalId":94208,"journal":{"name":"Social cognitive and affective neuroscience","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11799862/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143076422","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}
