To the question of whether Chomsky's hypothesized Language Acquisition Device (LAD) in young children is an adequate and feasible model of language acquisition, this paper answers that LAD should be reformulated so as to include semantics; that "informant presentation" rather than "text presentation" is responsible for language…

This report describes an investigation of the acquisition by children of a symbolic system, specifically English nomenclature--that set of nouns that serves the function of naming, denoting, or referring to objects. The five studies involve nine experiments dealing with one or another of the aspects of this problem. Two questions guided these…

This paper studies aspects of the conceptual basis for language acquisition, with a focus on the perceptual-cognitive skills used to assign meanings to words. A first assumption is that the correspondence between adult and child perceptual features allows for early communication. Apparently, in the first year, naming is characterized by…

The research reported is part of an investigation into the acquisition of grammar, using nonlinguistic information from situational and behavioral context to analyze the development of linguistic expression. Three children were seen for approximately 8 hours, every 6 weeks, in their homes, from the age of 19 months--soon after the earliest…

Explores the underlying knowledge that children have about the relationship between the structure of requests and the relative status of speakers and listeners. Shows that the three age groups (preschoolers, 5-year-olds, and 10-year-olds) could systematically differentiate the requests by means of syntactic directness or semantics. (HOD)

One of the most remarkable aspects of the babbling of some babies is that it is produced with intonation contours that sound very much like adult sentence melodies. This study reviews the literature and examines longitudinal data collected from seven children. Some of the non-adult-like syntactic uses made of intonation by children for…
