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:…

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 of 2.5 and 3.5 year olds indicated that children of this age do not know many names for solid substances but can be taught names for them; that children represent the names as mass nouns and possibly adjectives; and that there is development of children's nonlinguistic knowledge of substances between the ages of 2.5 and 3 years.

The phonotactic development of one child is traced from age 3;9 to 5;3. Data are presented in a table indicating both the child's phonological equivalent of adult consonant sequences and the range distinguished by the child at a given stage. (CHK)

This is a quarterly report of a project involving the analysis of the language of four Puerto Rican children living in the Boston area who are learning Spanish as a first language. The children, all male, ranged in age from 17 months to 37 months during the period of study. All had some contact with English. The data were transcriptions of…

The relation of imaginative play to psycholinguistic development was investigated in a sample of disadvantaged preschool children. The children were assigned to high and low play groups based on their level of play organization. The high play group engaged in more task-relevant speech during play than did the low play group.

Reports on a child who evidently used a gestalt strategy (proceeding from the whole to the parts) in learning his first language. Further evidence for a gestalt strategy exists in the literature, albeit implicitly, and any theory of language or language acquisition should be able to account for it. (Author/KM)

Children may be able to gain partial information about the meaning of a word from clues, such as how it is used in a sentence and what words it is contrasted with. This strategy, known as "fast mapping," may provide a very useful first step in language learning. One question which arises from studies of fast mapping is whether fast…

Extensive longitudinal data were gathered on a child's entry into the symbolically mediated modal world by examining changes in the semantics and pragmatics of her uses of modal auxiliary verbs. The data are 53 transcripts of natural conversations between a girl, Nina, and her mother recorded periodically from her 23rd month to her 39th month. The…

The development of relative clauses in child speech was investigated using an elicited production task instead of spontaneous speech samples. In an elicited production task, the context is manipulated so that a complex sentence must be used for communication. Thirty-six English speaking children from 3 to 5 years old were provided with contexts…

Children's understanding of the nature of polar terms and comparative terms between the polar opposites is discussed. (CHK)
