The nature of the task of defining words by means of other words and the development of language responses (from children aged four to seven) are discussed in terms of a linguistic analysis of the definitional form and its semantic relations. (Author/RM)

In four studies, 60 two- and three-year-olds were studied in an elicited imitation task wherein the linguistic form of sentences was varied according to conjunction structure and pattern of redundancy deletion in conjunction reduction. Both factors were found to affect imitation. (Author/RM)

The comprehension ability of 36 children at three stages of telegraphic speech was assessed using active behavioral responses to declarative and imperative sentences. A significant increase in verbal and behavioral appropriateness with age was found for imperative and declarative forms. Results are compared with Shipley, Smith and Gleitman's…

Two transitional phases in the child's early language development are described; the first occurs between prelinguistic vocalization and one-word speech and the second between one-word and patterned speech. Cognitive, linguistic and affective inputs to the acquisition of reference and syntax are discussed in the light of the transitional…

Recent attempts to classify the meanings of two-word utterances expressed by young children have assumed that children always intend one of the meanings adults might express. This paper challenges that assumption and suggests an alternative approach to determining the meaning of these utterances. (Author/RM)

In this longitudinal investigation of the emerging grammar of seven children, differences in linguistic acquisition were observed. Analyses revealed two distinct styles of syntactic acquisition that appeared to be sex- and speed-related with specific ties to particular utterance types and grammatical-relational specification. (Author/RM)

The written compositions of 11-year-olds in Great Britain's National Child Development Study were analyzed using the T-unit length as a measure of syntactic maturity and composition length as a measure of productivity. Results are discussed in relation to cognitive and linguistic development. (Author/RM)

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)
