Previous work with adolescents and adults suggests that variability in sensory processing may have a strong genetic basis. Yet, little is known about the etiological factors influencing sensory differences in infancy, when brain circuits supporting social and non\u2010social cognition are sculpted and learning about the world via sensory input largely occurs in interaction with caregivers.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      We analysed data from a community sample of monozygotic (MZ) and dizygotic (DZ) 5\u2010month\u2010old same\u2010sex twins (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u2009285 pairs,\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u2009158 MZ pairs,\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u2009150 male pairs) from the BabyTwins Study in Sweden (BATSS) using exploratory factor analysis, generalised estimating equations and multivariate twin models to delineate the phenotypic and etiological structure of individual variability across different sensory processing dimensions, as measured by the Infant\/Toddler Sensory Profile.

Sensory domains also showed etiological separability, with unique genetic influences to each domain, while contributions from shared environment were in part shared across domains. A higher incidence of tactile\u2010related behaviours and behaviours associated with sensory sensitivity, sensation avoiding, and low registration were significantly associated with higher levels of autistic traits in toddlerhood.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This study provides a map of the phenotypic and etiological structure of sensory processing in infancy, which will be informative for studies of both typical and atypical development.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/jcpp.14143","type":"journal-article","created":{"date-parts":[[2025,3,7]],"date-time":"2025-03-07T20:56:12Z","timestamp":1741380972000},"page":"1182-1196","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Different sensory dimensions in infancy are associated with separable etiological influences and with autistic traits in toddlerhood"],"prefix":"10.1111","volume":"66","author":[{"given":"Giorgia","family":"Bussu","sequence":"first","affiliation":[{"name":"Development and Neurodiversity Lab, Department of Psychology Uppsala University  Uppsala Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ana Maria","family":"Portugal","sequence":"additional","affiliation":[{"name":"Development and Neurodiversity Lab, Department of Psychology Uppsala University  Uppsala Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Terje","family":"Falck\u2010Ytter","sequence":"additional","affiliation":[{"name":"Development and Neurodiversity Lab, Department of Psychology Uppsala University  Uppsala Sweden"},{"name":"Department of Women's and Children's Health, Center of Neurodevelopmental Disorders (KIND), Centre for Psychiatry Research Karolinska Institutet &amp;
