Аннотация:The architecture of grammatical development in the talk of young children is the central concern of language acquisition research. The critical task of language acquisition scholarship over the last several decades has been to account for when, how, and why children use and understand grammatical forms over the course of the early period of their lives. Language socialization – the process in which children are socialized both through language and to use language within a community (Ochs and Schieffelin 1984; Schieffelin and Ochs 1986a, b) – has been largely examined without regard to the dynamics of grammatical development, focusing, rather, on culturally relevant communicative practices and activities. In this discussion, we reverse this orientation and focus directly on the role of language socialization in the acquisition of grammatical competence.
