  1. 1. Age and Constraints on Language Learning : First Language Retention and Second Language Acquisition in International Adoptees

    Abstract : This thesis investigates the influence of age of acquisition on the long-term second language development of international adoptees. Because age of acquisition typically coincides with the onset of bilingualism, the study of maturational age effects in second language acquisition has been empirically and conceptually entangled with changes in language input and use.

    Abstract : The present study follows in the tradition of those seeking to understand linguistic behavior from a cognitive and socio-biological perspective (Bates, Benigni, Bretherton, Camaioni and Volterra 1979, Lindblom 1992, Hauser 1996) by tracing the development of a non-linguistic vocal behavior in relation to communicative and early lexical advances. More specifically the study focuses on the occurrence of what are termed ìcommunicative gruntsî and their functional relationship to adult based word use in one Swedish boy from 11 to 19 months of age.
