Using the handmotor laterality blackboard, developmental change in symmetric bimanual motor function for 413 children in groups of 3 to 10 years of age shows synchronicity increased between groups 3 and 5 years of age; but between groups 5 and 7 years of age, given immature coupling, one hand may still disturb the movements of the other one. Between groups 7 and 9 years of age, the hands gradually stop disturbing each other and move independently and fluently. Changes in intermanual coupling with increasing unimanual independence represent expression of changing interhemispheric integration across groups. This promotes optimal laterality and task distribution between the hands. Maturation of the corpus callosum is inferred to be a factor in these ontogenetic changes which ultimately lead to optimal left hemisphere specialization for actions such as fluent writing.<\/jats:p>","DOI":"10.2466\/pms.109.1.3-29","type":"journal-article","created":{"date-parts":[[2010,9,20]],"date-time":"2010-09-20T06:44:08Z","timestamp":1284965048000},"page":"3-29","source":"Crossref","is-referenced-by-count":8,"title":["Ontogenesis of Laterality in 3- to 10-yr.-Old Children: Increased Unimanual Independence Grounded on Improved Bimanual Motor Function"],"prefix":"10.1177","volume":"109","author":[{"given":"W.","family":"van Grunsven","sequence":"first","affiliation":[{"name":"Institute for Remediation of Learning Disabilities Eindhoven, The Netherlands"},{"name":"Katholieke Universiteit Leuven, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Vuylsteke-Wauters","sequence":"additional","affiliation":[{"name":"Center of Statistics"},{"name":"Katholieke Universiteit Leuven, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.","family":"Njiokiktjien","sequence":"additional","affiliation":[{"name":"Developmental Dysphasia Foundation, Amsterdam, The Netherlands"},{"name":"Katholieke Universiteit Leuven, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Vranken","sequence":"additional","affiliation":[{"name":"Faculty of Kinesiology and Rehabilitation Sciences"},{"name":"Katholieke Universiteit Leuven, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2009,8,1]]},"reference":[{"key":"bibr1-pms.109.1.3-29","doi-asserted-by":"publisher","DOI":"10.1111\/j.2044-8295.1972.tb01282.x"},{"key":"bibr2-pms.109.1.3-29","volume-title":"Enfants gauchers, enfants droitiers, une \u00e9preuve de lat\u00e9ralit\u00e9 usuelle.","author":"Auzias M.","year":"1975"},{"key":"bibr3-pms.109.1.3-29","doi-asserted-by":"publisher","DOI":"10.1016\/S0010-9452(08)70110-2"},{"key":"bibr4-pms.109.1.3-29","doi-asserted-by":"publisher","DOI":"10.1207\/s15326942dn2903_2"},{"key":"bibr5-pms.109.1.3-29","first-page":"185","volume":"13","author":"Berg\u00e8s J.","year":"1965","journal-title":"Revue de Neuropsychiatrie Infantile"},{"key":"bibr6-pms.109.1.3-29","doi-asserted-by":"publisher","DOI":"10.1016\/S0304-3940(00)01592-5"},{"key":"bibr7-pms.109.1.3-29","doi-asserted-by":"publisher","DOI":"10.1016\/0028-3932(77)90040-9"},{"key":"bibr8-pms.109.1.3-29","doi-asserted-by":"publisher","DOI":"10.2307\/1128815"},{"key":"bibr9-pms.109.1.3-29","doi-asserted-by":"publisher","DOI":"10.1016\/j.brainresrev.2005.03.005"},{"key":"bibr10-pms.109.1.3-29","doi-asserted-by":"publisher","DOI":"10.1007\/s002219900272"},{"key":"bibr11-pms.109.1.3-29","doi-asserted-by":"publisher","DOI":"10.1080\/713755721"},{"key":"bibr12-pms.109.1.3-29","doi-asserted-by":"publisher","DOI":"10.1007\/s004220050567"},{"key":"bibr13-pms.109.1.3-29","doi-asserted-by":"publisher","DOI":"10.1016\/B978-012759440-8\/50022-0"},{"key":"bibr14-pms.109.1.3-29","doi-asserted-by":"publisher","DOI":"10.1037\/h0080122"},{"key":"bibr15-pms.109.1.3-29","first-page":"817","volume":"63","author":"De Ajuriaguerra J.","year":"1955","journal-title":"Presse M\u00e9dicale"},{"key":"bibr16-pms.109.1.3-29","doi-asserted-by":"publisher","DOI":"10.1016\/j.actpsy.2006.03.003"},{"key":"bibr17-pms.109.1.3-29","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-8749.1973.tb05174.x"},{"key":"bibr18-pms.109.1.3-29","doi-asserted-by":"publisher","DOI":"10.1016\/0028-3932(76)90074-9"},{"key":"bibr19-pms.109.1.3-29","doi-asserted-by":"publisher","DOI":"10.1111\/1467-7687.00147"},{"key":"bibr20-pms.109.1.3-29","doi-asserted-by":"publisher","DOI":"10.1002\/dev.10117"},{"key":"bibr21-pms.109.1.3-29","volume-title":"Visual agnosia.","author":"Farah M.
