Examined the relationship between infants' early verbal imitation, when the ability to copy behaviors first emerges, and their lexical development during the second year of life. Twenty infants were examined longitudinally at ages 10, 13, 17, and 21 months. Suggests that infants' early imitation of words not in their repertoires predicts and may…

This report describes an investigation of the acquisition by children of a symbolic system, specifically English nomenclature--that set of nouns that serves the function of naming, denoting, or referring to objects. The five studies involve nine experiments dealing with one or another of the aspects of this problem. Two questions guided these…

Six preschool children, mostly from poverty-level backgrounds, were taught to make descriptive statements about objects. The category-descriptor statements were organized and sequenced into four clusters. As sets of new statements were successively taught and evaluated, the number and diversity of probed category and descriptor terms steadily and…

This paper studies aspects of the conceptual basis for language acquisition, with a focus on the perceptual-cognitive skills used to assign meanings to words. A first assumption is that the correspondence between adult and child perceptual features allows for early communication. Apparently, in the first year, naming is characterized by…

Vocabulary diversity is a measure either of the language spoken within a fixed time period or of the total utterances, sentences, or words. To measure children's language development as revealed by the diversity of their spoken expression, a comparison was made of the vocabulary of 15 first-grade children of average ability, of first-grade primers…

Presents four articles in the context of workshop discussions on characteristics of environments that promote language development: (1) "Children's Conversations: Why are They Important?"; (2) "Ways of Talking: Respecting Differences"; (3) Paul's Talk: Teachers and Parents Look at a Child's Language"; and (4) "In the…

One of the most remarkable aspects of the babbling of some babies is that it is produced with intonation contours that sound very much like adult sentence melodies. This study reviews the literature and examines longitudinal data collected from seven children. Some of the non-adult-like syntactic uses made of intonation by children for…

Every speech community has a baby talk register (BT) of phonological, grammatical, and lexical features regarded as primarily appropriate for addressing young children and also for other displaced or extended uses. Much BT is analyzable as derived from normal adult speech (AS) by such simplifying processes as reduction, substitution, assimilation,…

This paper explores the relation between the communicative and categorical functions of language and the acquisition of language production. Three major factors in language acquisition are communication, ability for representation and the process of categorization. This paper offers evidence that a sudden and dramatic increase in lexical skill…

This paper describes the development and use of language training procedures, referred to as cues-pause-point procedures, that rely on behavioral principles and simple and natural teaching procedures and that are exhibited in many normal parent-child or teacher-student verbal interactions. The procedures have been effective in teaching severely…

This analysis of Brazilian baby talk (BT) includes data from two sources: elicitations of the use of BT from three mothers, all of whom have university degrees, and observations of adult-child interactions in the home. The data shows Ferguson's modified list of thirty lexical items that frequently have BT forms in various languages and the…

This document presents details for a supplemental oral language development program for children in the elementary grades learning to speak American English as a second language. The booklet discusses the purpose and objectives of the program and describes the materials to be used, the physical set-up, teaching techniques and learning activities…
