Running Head DEVELOPMENTAL CHANGES IN LANGUAGE ACQUISITION Diverging paths Developmental changes in second language acquisition between three and five years of age Jesse Snedeker1 Joy Geren1 and Carissa L Shafto2 1 2 Harvard University University of Louisville Address Correspondence to Jesse Snedeker 1136 WJH 33 Kirkland St Cambridge MA 02138 Phone 617 495 3873 fax 617 384 7944 snedeker wjh harvard edu 1 Abstract Language development is characterized by predictable shifts in the words children produce and the complexity of their utterances Because language acquisition and cognitive development occur simultaneously in infants it is difficult to determine the causes of these shifts These studies explore the effects of cognitive maturation on language development examining the acquisition of English in internationally adopted preschoolers Parental reports CDI were collected from 48 preschoolers within the first year after they were adopted from China or Eastern Europe Children who were adopted at two or three years of age showed the same developmental patterns in language production as monolingual infants matched for vocabulary size Early on their vocabularies were dominated by nouns and social words with the proportion of predicates and closed class words increasing with age Thus shifts in lexical composition appear in older learners and are unlikely to reflect the development of new conceptual resources Children who were adopted at four or five deviated from this pattern acquiring fewer nouns and more predicates in the early stages of acquisition Affects of the birth language on acquisition were limited to the older children suggesting that older children may employ different strategies in word learning In both groups grammatical development and lexical development were synchronized in precisely the same way that they are in infancy raising the possibility that word production and grammatical production are causally connected Keywords language development
