Turkish-English Language Acquisition

这项纵向研究调查了一名1岁零8个月和4岁零6个月的儿童同时习得英语和土耳其语的情况。我们将比较以下两种语言的单语习得情况，以及英语和土耳其语的连续习得情况，以及之前研究的儿童在2岁零6个月和3岁零3个月之间丧失土耳其语的情况。该项目在双语习得案例研究中特别令人感兴趣，因为涉及的两种语言在类型上是不同的。它还提供了使用同一对语言同时和连续获得双语的为数不多的比较之一。这些发现将与语言习得和社会化、双语以及语言和认知发展之间的关系等理论相关。

This longitudinal study investigates the simultaneous acquisition of English and Turkish by a child between the ages of 1 year, 8 months and 4 years, six months. Comparisons will be made with the monolingual acquisition of each of these languages as well as the successive acquisition of English and Turkish, followed by the loss of Turkish between the ages of 2 years, six months and 3 years, 3 months in a child previously studied. The project is of special interest among case studies in bilingual acquisition, because the two languages involved are typologically different. It also provides one of the few comparisons of simultaneous and successive bilingual acquisition using the same pair of languages. Findings will be relevant to theories of language acquisition and socialization, bilingualism, and relations between language and cognition in development.
