Reports two studies in which preschool and elementary school children's preference for certain strategies in copying a compound figure were interpreted in terms of a simple phrase structure. The phrase structure involved movements controlled with minimal degrees of freedom. (Author/JMB)

Presents a study of the effects of training 18 subjects, 28-40 months, in the use of two-word subject-verb utterances. The study focused on: (1) the number of different semantic relations underlying the subject-verb form in which the child is trained, and (2) the relationship between the semantic relations and ongoing, experimentally manipulated…

Examines the effects of chronological age, mental age, and intelligence quotient on verbal imitation of five-year-old children, concluding that transition occurs during the fifth year of life as young five-year-olds emitted more mimical and less conceptual responses than older five-year-olds. (RB)

Two studies investigated linguistic representations underlying English-speaking 2.5-year-olds' production of transitive utterances. Findings indicated that children trained with pronouns and nouns could produce a transitive utterance creatively with a novel verb. Results suggest that English-speaking children build many of their early linguistic…

The basis for acquisition of categories in child language was investigated. The early encoding of the distinction between mass and count nouns was examined to determine whether children categorize them on the basis of semantic type or syntactic regularities. An experiment was designed in which semantic and syntactic cues were in competition:…

Listeners had more difficulty identifying vowels uttered by 4-year-olds classified as late language users than those uttered by 4-year-olds classified as normal. (MH)

Speaker immersion is a tactic that uses multiple establishing operations to increase speaker behavior for individuals with limited mand and tact repertoires. The purpose of this paper was to evaluate the effects of speaker immersion on the number of independent mands, tacts, and autoclitics emitted by young children with verbal delays. In the…

Three experiments on the comprehension and acquisition of temporal terms are described. Methodological innovations were applied to control for possible methodological effects on children's performance. Each experiment involved 24 children aged 3 to 5. In the first experiment, subjects manipulated toys in response to instructions containing the…

The use of imitation as a language learning strategy was explored in a case study of a child in a Mandarin-speaking family. Recordings were made over the course of 3 months, from the ages of 2 years 10 months to 3 years 1 month. It is argued that restrictive criteria regarding identity of form and temporal proximity of utterances have severely…

Analysis of 24 spontaneous speech samples from children at 24 and 30 months revealed a correlated progression in the form, function, and meaning of adjective modifiers used with increased language development. (Author/DEP)

This study attempted to test the notion that the reinforcing stimuli which maintain high rates of speech may not consist solely of events extrinsic to the person but may involve (sensory) stimulation generated by the behavior itself. (Author)

Examines whether novelty produces more or less attention than familiarity and incongruity, and whether children's learning behavior is related to these differences in attention. Subjects were 43 three- to five-year-old children. (BD)

Twelve 21/2-year-old children received adult verbal intervention selectively directed toward acquisition of either question forms or verb forms. Findings showed that children who received verb intervention acquired new verb structures while children who received question intervention acquired new forms of questions. (Author/JMB)
