Although research has found that delayed imitation produces superior learning outcomes compared with other observational learning strategies, the underlying reason for this advantage remains unclear.

However, performance in the delayed imitation condition did not differ significantly from that in the observation\u2010only condition. At the neural level, delayed imitation elicited stronger IBS in the right dlPFC, with both observation and imitation phases contributing to this increased synchronization. Crucially, IBS in the right dlPFC was positively correlated with learning performance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>These findings suggest that the advantage of delayed imitation is associated with enhanced brain\u2010to\u2010brain coupling between the demonstrator and the learner, providing novel evidence that interbrain coupling contributes to effective observational learning.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/brb3.71683","type":"journal-article","created":{"date-parts":[[2026,8,21]],"date-time":"2026-08-21T03:17:47Z","timestamp":1787282267000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Brain\u2010to\u2010Brain Coupling Is Associated With the Benefits of Delayed Imitation in Skill Acquisition: An fNIRS Study"],"prefix":"10.1002","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0202-997X","authenticated-orcid":false,"given":"Cuirong","family":"Yang","sequence":"first","affiliation":[{"name":"School of Smart Education Jiangsu Normal University  Xuzhou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0287-4970","authenticated-orcid":false,"given":"Linwei","family":"Yu","sequence":"additional","affiliation":[{"name":"Shanghai Key Laboratory of Mental Health and Psychological Crisis Intervention School of Psychology and Cognitive Science East China Normal University  Shanghai China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-6479-0755","authenticated-orcid":false,"given":"Liangchuan","family":"Mi","sequence":"additional","affiliation":[{"name":"School of Water Conservancy Engineering Zhejiang Tongji Vocational College of Science and Technology  Hangzhou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1667-2381","authenticated-orcid":false,"given":"Ming","family":"Yin","sequence":"additional","affiliation":[{"name":"Investigation Department Jiangsu Police Institute  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0243-9060","authenticated-orcid":false,"given":"Yi","family":"Hu","sequence":"additional","affiliation":[{"name":"Shanghai Key Laboratory of Mental Health and Psychological Crisis Intervention School of Psychology and Cognitive Science East China Normal University  Shanghai China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,20]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.3390\/brainsci11070885"},{"key":"e_1_2_11_3_1","volume-title":"Social Learning Theory","author":"Bandura A.","year":"1977"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.3389\/frvir.2022.934642"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.psych.59.103006.093639"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1756\u20108765.2010.01115.x"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.3389\/fnhum.2017.00431"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1080\/027249899390882"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.chb.2018.01.017"},{"key":"e_1_2_11_10_1","doi-asserted-by":"publisher","DOI":"10.1037\/0096\u20103445.136.4.539"},{"key":"e_1_2_11_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0028\u20103932(99)00134\u20107"},{"key":"e_1_2_11_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuroimage.2009.12.112"},{"key":"e_1_2_11_13_1","doi-asserted-by":"publisher","DOI":"10.3389\/fpsyg.2017.01689"},{"key":"e_1_2_11_14_1","doi-asserted-by":"publisher","DOI":"10.1207\/s15327647jcd0702_4"},{"key":"e_1_2_11_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cognition.2007.04.010"},{"key":"e_1_2_11_16_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF02447083"},{"key":"e_1_2_11_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.humov.2021.102776"},{"key":"e_1_2_11_18_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuroimage.2009.11.050"},{"key":"e_1_2_11_19_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41467\u2010018\u201004819\u2010z"},{"issue":"32","key":"e_1_2_11_20_1","first-page":"27","article-title":"The Role of Scheduling in Learning Through Observation","volume":"1","author":"Deakin J.
