We recorded dual-brain mobile EEG from adult human participants of both sexes (16 female, 2 male) and a dance instructor across six five-minute conditions that vary these ingredients independently: solitary rest, direct eye gaze, conversation, teacher-led and participant-led mirroring, and free improvisation, with concurrent head-mounted accelerometry. Referencing each condition to eye gaze \u2014 socially engaging but nearly motionless \u2014 rather than to solitary rest partitioned the response. The components proved dissociable. Nonverbal social attention alone reorganized the power spectrum, flattening the aperiodic exponent (g = \u22120.97) and desynchronizing alpha-band oscillations (g = \u22120.90), while leaving inter-regional connectivity unchanged (amplitude g = +0.15; phase g = +0.11). Verbal engagement added high-frequency amplitude coupling (g = +2.61) without further spectral change. Coordinated movement added a decrease in theta\/alpha coupling involving the frontoparietal-control network (g = \u22120.59), the signature of an externally directed state, alongside a further spectral shift (g = \u22120.61). Movement-vigor covariates, corticokinematic coherence, and aperiodic-adjusted power indicated that the spectral effects were cortical rather than myogenic. Four weeks of improvisational dance training increased empathic responsiveness to others\u2019 distress relative to a movie control (g = 0.82). Coordinated social movement thus acts on the brain componentially, with mutual attention rather than motor load establishing the engaged state.<\/jats:p>","DOI":"10.64898\/2026.09.24.754139","type":"posted-content","created":{"date-parts":[[2026,9,30]],"date-time":"2026-09-30T06:00:28Z","timestamp":1790748028000},"source":"Crossref","is-referenced-by-count":0,"title":["Social attention and coordinated movement produce dissociable spectral and network changes during dyadic improvisational dance"],"prefix":"10.64898","author":[{"given":"Rachel M.","family":"DeLauder","sequence":"first","affiliation":[{"name":"Department of Human Nutrition, Foods, and Exercise, Virginia Tech, Blacksburg, VA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Noor","family":"Tasnim","sequence":"additional","affiliation":[{"name":"Translational Biology, Medicine, and Health Graduate Program, Virginia Tech, Roanoke, VA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mackenzie","family":"Aychman","sequence":"additional","affiliation":[{"name":"Department of Human Nutrition, Foods, and Exercise, Virginia Tech, Blacksburg, VA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mary","family":"Gahagan","sequence":"additional","affiliation":[{"name":"School of Neuroscience, Virginia Tech, Blacksburg, VA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jessica","family":"Purevtugs","sequence":"additional","affiliation":[{"name":"School of Neuroscience, Virginia Tech, Blacksburg, VA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jesse","family":"Newpol","sequence":"additional","affiliation":[{"name":"School of Neuroscience, Virginia Tech, Blacksburg, VA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryan","family":"Frank","sequence":"additional","affiliation":[{"name":"School of Neuroscience, Virginia Tech, Blacksburg, VA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Grace","family":"Grizzell","sequence":"additional","affiliation":[{"name":"Department of Biology, Virginia Tech, Blacksburg, VA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Grace","family":"Nobriga","sequence":"additional","affiliation":[{"name":"School of Neuroscience, Virginia Tech, Blacksburg, VA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah","family":"Rose","sequence":"additional","affiliation":[{"name":"School of Neuroscience, Virginia Tech, Blacksburg, VA, USA"},{"name":"Department of Psychology, Virginia Tech, Blacksburg, VA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julia C.","family":"Basso","sequence":"additional","affiliation":[{"name":"Department of Human Nutrition, Foods, and Exercise, Virginia Tech, Blacksburg, VA, USA"},{"name":"School of Neuroscience, Virginia Tech, Blacksburg, VA, USA"},{"name":"Center for Research on Health Behaviors, Fralin Biomedical Research Institute at VTC, Roanoke, VA, USA"},{"name":"Institute for Creativity, Arts, and Technology, Virginia Tech, VA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"54368","reference":[{"key":"2026100319000613000_2026.09.24.754139v1.1","doi-asserted-by":"publisher","DOI":"10.3389\/fnhum.2020.584312"},{"key":"2026100319000613000_2026.09.24.754139v1.2","doi-asserted-by":"publisher","DOI":"10.1016\/j.neubiorev.2015.01.004"},{"key":"2026100319000613000_2026.09.24.754139v1.3","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-025-58620-w"},{"key":"2026100319000613000_2026.09.24.754139v1.4","doi-asserted-by":"publisher","DOI":"10.1080\/17482631.2021.1950891"},{"key":"2026100319000613000_2026.09.24.754139v1.5","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuroimage.2011.11.084"},{"key":"2026100319000613000_2026.09.24.754139v1.6","doi-asserted-by":"crossref","unstructured":"Fischman D (2015) Therapeutic relationships and kinesthetic empathy.
