Yet findings remain inconsistent, partly due to reliance on discrete emotion categories that neglect affective dimensions. Guided by a valence\u2013arousal framework, this study re\u2010examined facial emotion recognition in preschool children with ASD using eye\u2010tracking and pupilometry. Eighty\u2010two Chinese preschoolers (40 ASD, 42 typically developing [TD]) completed an emotion recognition task with facial stimuli systematically varied in valence (positive vs. negative) and arousal (high vs. low). Eye movements and pupil size were analyzed within a 2 (group)\u2009\u00d7\u20092 (valence)\u2009\u00d7\u20092 (arousal)\u2009\u00d7\u20094 (AOI: eyes, nose, mouth, other) design. Results showed robust effects of valence: TD children allocated more fixations and longer gaze to positive faces, especially the eye region, whereas ASD children showed attenuated patterns. Arousal effects were weaker but interacted with valence, with high\u2010arousal negative faces eliciting avoidance and high\u2010arousal positive faces enhancing pupil responses. These findings highlight valence\u2013arousal asymmetry as a key mechanism underlying atypical emotion processing in preschool ASD and underscore the value of dimensional approaches for early socioemotional assessment and intervention.<\/jats:p>","DOI":"10.1002\/aur.70295","type":"journal-article","created":{"date-parts":[[2026,6,20]],"date-time":"2026-06-20T05:25:41Z","timestamp":1781933141000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Valence\u2010Arousal Asymmetry: Rethinking Facial Emotion Recognition in Preschool Autism Through Eye\u2010Tracking"],"prefix":"10.1002","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-3018-0068","authenticated-orcid":false,"given":"FanShuai","family":"Bu","sequence":"first","affiliation":[{"name":"School of Education Science Qingdao University  Qingdao China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"RuoXi","family":"Teng","sequence":"additional","affiliation":[{"name":"School of Education Science Qingdao University  Qingdao China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mingyu","family":"Zhang","sequence":"additional","affiliation":[{"name":"Qingdao Chenxing Experiment School  Qingdao China"},{"name":"School of Teacher Education East China Normal University  Shanghai China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hang","family":"Zhou","sequence":"additional","affiliation":[{"name":"School of Education Science Qingdao University  Qingdao China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Lyu","sequence":"additional","affiliation":[{"name":"Qingdao Chenxing Experiment School  Qingdao China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8101-3724","authenticated-orcid":false,"given":"Lu","family":"Jiao","sequence":"additional","affiliation":[{"name":"School of Education Science Qingdao University  Qingdao China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8725-3988","authenticated-orcid":false,"given":"Chen","family":"Cai","sequence":"additional","affiliation":[{"name":"School of Education Science Qingdao University  Qingdao China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qian","family":"Jin","sequence":"additional","affiliation":[{"name":"School of Education Science Qingdao University  Qingdao China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,6,19]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1177\/09544119231170683"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1192\/bjp.2022.157"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.3389\/fncir.2023.1275896"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.actpsy.2025.104720"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.tics.2012.02.007"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/aur.1479"},{"key":"e_1_2_10_8_1","unstructured":"Constantino J.
