In addition to componential aspects of verb meaning, children must also acquire a representation of each verb's combinatorial properties or propositional schema, i.e., the number of arguments with which it is obligatorily or optionally associated. The present study investigated developmental changes in children's awareness of the combinatorial…

Contains status reports of research in three areas of speech production: functional properties of the speech production apparatus, control principles underlying speech production, and the biological basis of the speech production process. (RL)

Considers three different topics in speech research from the viewpoint of the physiology of the speech production mechanism: laryngeal control for voicing distinctions, articulatory dynamics in normal and dysarthric cases, and central mechanism of skilled movements. Includes a summary of a discussion on speech production. (RL)

Verb nominalization in Navajo is a strategy by which children create category labels when the adult lexical item is not known; it allows for the creation of uniquely descriptive category labels. This study was based on a series of interviews with Navajo children aged four-and-a-half to approximately ten years, all native speakers of Navajo with…

Research in the active-passive verb relation has indicated that there is an interaction between syntactic form and verb semantics among children of preschool age. The present study examines the contribution of active-passive syntax and verb semantics to comprehension difficulty for preschoolers, 6-year-olds, 7-year-olds, and adults. An additional…

A major concern in recent research is whether perceptual or functional information is of primary importance in children's early word meanings. In the study described here, artificial objects were used so that form and function could be independently manipulated. There were 57 subjects, ranging in age from 2.5 years to adulthood. The subjects were…

Augments Michael Studdert-Kennedy's state-of-the-art report on speech perception research (EJ 227 656) with comments on categorical perception of speech and nonspeech stimuli, speech perception in context, the role of prosody, and development/impairments of speech perception. Includes a summary of a discussion on speech perception research. (RL)

A study explored the acquisition of "se" by Spanish-speaking children in Madrid, Spain, looking at: (1) acquisition of multifunctional forms; and (2) the course of acquisition for a linguistic expression that has both anaphoric and non-anaphoric functions, and its relevance to Binding Theory approaches to the acquisition of reflexives.…

Sentences produced by children and adults in telling stories are analyzed, with particular emphasis on developmental trends in sentence length, the degree of cohesion between clauses, and the internal coherence of sentence content. Subjects for the study were 10 adults and 60 Japanese children in six different age groups. Each subject was…

There are problems in interpreting the naming behavior of children. Children may misname a word because the word is absent from their vocabulary, because it is not yet firmly established, or because of a word retrieval or lexical assessing problem. Preliminary results are reported of an experimental technique designed to account for these…

Children's understanding of the epistemological terms "know" and "guess" was investigated in two studies with four- to ten-year-old subjects. Two adult players guessed at the location of a ball hidden in one of two boxes. On each trial the child was asked questions about "knowing" and "guessing" both before and after the guessing took place.…

This paper reviews some of the observations made by Vygotsky about the structure and content of inner speech and its precursor egocentric speech, also called private speech. Recent advances in certain areas of linguistics are used to clarify and develop these observations. In particular, the paper focuses on Vygotsky's ideas about the predicative…

The adequacy of mean length of utterance (MLU) as a criterion for matching retarded and normally developing children was investigated. Six normally developing and four retarded subjects were matched on MLU. Although matched on MLU, these two groups of children demonstrated both quantitative and qualitative differences in their use of language.…

The existence of a developmental sequence for the acquisition of specific complex syntactic structures in English was investigated through an analysis of eight studies of Danish subjects. The studies involved Danish speaking subjects acquiring English as a second language at ages 7-10, 13, and 18. The evidence from these studies demonstrate a…

Two experiments were designed to assess children's ability to understand recursive structures of thinking which include thinking about contiguous people, thinking about action between people, thinking about thinking, and thinking about thinking about thinking. In Experiment I, 32 second, fourth, sixth, and eighth graders were tested on eight tasks…
