Reports on a study investigating the relationship between children's linguistic environment and language acquisition. In particular, the study examined the effect of mothers' speech on subsequent child speech. (Author/AM)

Reports on an investigation of the surface forms used by mothers to direct their children's behavior, and of the ways in which these forms are modified as the children grow older and their comprehension of indirect speech acts increases. (AM)

Measures of pragmatic development for children in the second year of life were developed based on a 30-minute language sample drawn from 20 children. Results support the view that the range of pragmatic functions grows steadily during the one-word and early two-word stage and that it is measurable. (Author/AM)

Preschool children aged 2.6 to 5.0 were presented with reversible active and passive sentences in four comprehension test settings. The children's response patterns were analyzed in terms of individual response patterns. Extralinguistic cues accounted for the most common patterns. (Author/AM)

Thirty children with a mean length of utterance ranging from 1.00 to 4 and an age range of 1.7 to 5.5 were tested for comprehension of two-noun possessive phrases. Three types of possessive relationships were used to uncover children's knowledge of the semantics and syntax of English possession. (Author/AM)

Presents an outline for a theory of syntax acquisition, surveys other approaches to language acquisition, and addresses the following methodological issues: (1) the relevance of linguistic theory to the model; (2) how the model is tested; and (3) the domain of the theory. (Author/AM)

Reports on research that sought to clarify Brown's (1973) research on acquisition order, syntactic complexity, semantic complexity, and the relationship among the three. (Author/AM)

This study is an attempt to investigate the efficacy of using existing semantic relations categories for understanding how children comprehend the verb "with" + noun construction. (Author)

The present study is an attempt to apply a paradigm to the shift of verbal behavior before and after the age of seven in order to see if linguistic contexts affect verbal behavior differentially before seven or after seven. (Author/CFM)

Investigates the linguistic abilities of a subgroup of grammatical specific language impaired (SLI) children, focusing on the use of referential expressions in a narrative discourse and providing insight into the underlying nature of grammatical SLI. Findings support the hypothesized modular nature of grammatical SLI children's underlying…
