Hyperscanning, which measures brain activity in multiple individuals simultaneously, can examine inter-brain synchronization as a possible signature of social coordination. In this study, we explore this synchronization during natural, everyday interactions in romantic couples. Forty-two dyads participated in a naturalistic behavioral paradigm while EEG was recorded. We measured behavioral dyadic reciprocity and negative states, and computed inter-brain synchronization using the circular correlation coefficient (CCorr) across multiple frequency bands (Theta [4-8\u2009Hz], Alpha [8-13\u2009Hz], and Beta [14-31\u2009Hz]). Positive interactions elicited greater dyadic reciprocity and fewer negative states compared to negative interactions. At the neural level, inter-brain synchronization in the beta band was significantly higher during positive compared to negative interactions. Mentalizing compared to counting elicited increased inter-brain synchronization in both alpha and beta bands, indicating that active sociocognitive processing enhances neural alignment between partners. These findings demonstrate that inter-brain dynamics provide a neural signature of both interaction valence and mentalizing engagement during real-world social interactions, putting forward inter-brain synchronization as a sensitive marker of sociocognitive coordination.<\/jats:p>","DOI":"10.1093\/scan\/nsag083","type":"journal-article","created":{"date-parts":[[2026,10,5]],"date-time":"2026-10-05T11:05:07Z","timestamp":1791198307000},"source":"Crossref","is-referenced-by-count":0,"title":["Positive interactions and active mentalizing facilitate inter-brain synchronization in couples"],"prefix":"10.1093","author":[{"given":"Isabella","family":"Schneider","sequence":"first","affiliation":[{"name":"Heidelberg University Department of General Psychiatry, Center for Psychosocial Medicine, , Vo\u00dfstr. 4, 69115 Heidelberg,","place":["Germany"]},{"name":"Federal Institute for Drugs and Medical Devices , Kurt-Georg-Kiesinger-Allee 3, 53175 Bonn,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Quentin","family":"Moreau","sequence":"additional","affiliation":[{"name":"Precision Psychiatry and Social Physiology Laboratory (PPSP), CHU Sainte-Justine Azrieli Research Center , Montr\u00e9al, Qu\u00e9bec,","place":["Canada"]},{"name":"University of Montr\u00e9al Department of Psychiatry, , Qu\u00e9bec,","place":["Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Neudecker","sequence":"additional","affiliation":[{"name":"Heidelberg University Department of General Psychiatry, Center for Psychosocial Medicine, , Vo\u00dfstr. 4, 69115 Heidelberg,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sabine C","family":"Herpertz","sequence":"additional","affiliation":[{"name":"Heidelberg University Department of General Psychiatry, Center for Psychosocial Medicine, , Vo\u00dfstr. 4, 69115 Heidelberg,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guillaume","family":"Dumas","sequence":"additional","affiliation":[{"name":"Precision Psychiatry and Social Physiology Laboratory (PPSP), CHU Sainte-Justine Azrieli Research Center , Montr\u00e9al, Qu\u00e9bec,","place":["Canada"]},{"name":"University of Montr\u00e9al Department of Psychiatry, , Qu\u00e9bec,","place":["Canada"]},{"name":"Mila \u2013 Quebec AI Institute , Montr\u00e9al, Qu\u00e9bec,","place":["Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,10,3]]},"container-title":["Social Cognitive and Affective Neuroscience"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/academic.oup.com\/scan\/advance-article-pdf\/doi\/10.1093\/scan\/nsag083\/71601420\/nsag083.pdf","content-type":"application\/pdf","content-version":"am","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/scan\/advance-article-pdf\/doi\/10.1093\/scan\/nsag083\/71601420\/nsag083.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,5]],"date-time":"2026-10-05T11:05:08Z","timestamp":1791198308000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/scan\/advance-article\/doi\/10.1093\/scan\/nsag083\/8864844"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,10,3]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1093\/scan\/nsag083","relation":{},"ISSN":["1749-5016","1749-5024"],"issn-type":[{"value":"1749-5016","type":"print"},{"value":"1749-5024","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,10,3]]},"article-number":"nsag083"}}
