We call this model DevLex\u2010II, based on the earlier DevLex model. DevLex\u2010II can simulate a variety of empirical patterns in children's acquisition of words. These include a clear vocabulary spurt, effects of word frequency and length on age of acquisition, and individual differences as a function of phonological short\u2010term memory and associative capacity. Further results from lesioned models indicate developmental plasticity in the network's recovery from damage, in a non\u2010monotonic fashion. We attribute the network's abilities in accounting for lexical development to interactive dynamics in the learning process. In particular, variations displayed by the model in the rate and size of early vocabulary development are modulated by (a) input characteristics, such as word frequency and word length, (b) consolidation of lexical\u2010semantic representation, meaning\u2010form association, and phonological short\u2010term memory, and (c) delayed processes due to interactions among timing, severity, and recoverability of lesion. Together, DevLex and DevLex\u2010II provide an accurate computational account of early lexical development.<\/jats:p>","DOI":"10.1080\/15326900701399905","type":"journal-article","created":{"date-parts":[[2010,10,18]],"date-time":"2010-10-18T19:07:52Z","timestamp":1287428872000},"page":"581-612","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":112,"title":["Dynamic Self\u2010Organization and Early Lexical Development in Children"],"prefix":"10.1111","volume":"31","author":[{"given":"Ping","family":"Li","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaowei","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brian","family":"Mac Whinney","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2007,7]]},"reference":[{"key":"e_1_2_7_2_1","volume-title":"Developmental neuropsychology: A clinical approach","author":"Anderson V.","year":"2001"},{"key":"e_1_2_7_3_1","doi-asserted-by":"crossref","first-page":"214","DOI":"10.1093\/oso\/9780195121933.003.0010","volume-title":"The changing nervous system: Neurobehavioral consequences of early brain disorders","author":"Bates E.","year":"1999"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1006\/drev.1993.1020"},{"key":"e_1_2_7_5_1","volume-title":"Handbook of child language","author":"Bates E.","year":"1995"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0305000900008680"},{"key":"e_1_2_7_7_1","first-page":"281","volume-title":"Handbook of developmental cognitive neuroscience","author":"Bates E.","year":"2001"},{"key":"e_1_2_7_8_1","first-page":"525","volume-title":"Handbook of neuropsychology, Vol. 8: Child neurology","author":"Bates E.","year":"2003"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0305000900002245"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1109\/TNN.2006.871720"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.7551\/mitpress\/3577.001.0001"},{"key":"e_1_2_7_12_1","first-page":"73","volume-title":"Explaining language universals","author":"Bowerman M.","year":"1988"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1080\/016909697386844"},{"key":"e_1_2_7_14_1","first-page":"117","volume-title":"Cognitive dynamics","author":"Burgess C.","year":"2000"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1037\/e400082009-004"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.ps.34.020183.001545"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1037\/0033-295X.112.2.347"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.3758\/BF03203646"},{"key":"e_1_2_7_19_1","volume-title":"Human behavior and the developing brain","author":"Dawson G.","year":"1994"},{"key":"e_1_2_7_20_1","doi-asserted-by":"publisher","DOI":"10.1080\/01690969008407066"},{"key":"e_1_2_7_21_1","volume-title":"Early lexical development","author":"Dromi E.","year":"1987"},{"key":"e_1_2_7_22_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.tics.2005.01.005"},{"key":"e_1_2_7_23_1","doi-asserted-by":"publisher","DOI":"10.7551\/mitpress\/5929.001.0001"},{"key":"e_1_2_7_24_1","first-page":"67","volume-title":"Proceedings of the fourth international conference on cognitive modeling","author":"Farkas I.","year":"2001"},{"key":"e_1_2_7_25_1","first-page":"553","volume-title":"Proceedings of the sixth joint conference on information sciences","author":"Farkas I.","year":"2002"},{"key":"e_1_2_7_26_1","doi-asserted-by":"publisher","DOI":"10.2307\/1166093"},{"key":"e_1_2_7_27_1","doi-asserted-by":"publisher","DOI":"10.1037\/0012-1649.40.4.621"},{"key":"e_1_2_7_28_1","doi-asserted-by":"publisher","DOI":"10.1080\/016909698386537"},{"key":"e_1_2_7_29_1","volume-title":"Working memory and language","author":"Gathercole S.
