The development of the Conversational Unit (CU) was investigated in a semilongitudinal study of three mother/son dyads in nonstructured spontaneous communication. The children were 19 to 23 months old at the start of the investigation. Sound films were recorded monthly during bathing and feeding times. After four months, verbal and nonverbal…

The question is addressed whether a child would develop a communication system if a conventional linguistic model is absent. Six congenitally deaf children, who were not exposed to Sign Language, were observed and videotaped at play in their homes at intervals of one to three months. The children ranged in age from 1 year, 5 months to 4 years, 1…

A SEPARATE LANGUAGE MANUAL FOR THE NEBRASKA ELEMENTARY ENGLISH CURRICULUM SUPPLEMENTS THE LANGUAGE-EXPLORATION SECTIONS OF THE UNITS IN GRADES ONE THROUGH SIX. THIS RESOURCE MANUAL PROVIDES AN INTRODUCTION TO MODERN LANGUAGE STUDY AND DESCRIBES ITS APPLICATION TO THE LANGUAGE LEARNING LEVELS OF CHILDREN. BY THE TIME CHILDREN ENTER JUNIOR HIGH…

Most studies of language acquisition overlook the fact that a child learns language in the context of acquiring the social skill of conversing known as "turn-taking." The few studies of verbal turn-taking in children suggest that prosodic features (suprasegmentals) and turn-taking skills are integrated by the age of two years, nine months, and…

The work reported here is part of an ongoing project to develop a language comprehension assessment instrument that: (1) is sensitive enough to pinpoint the particular language phenomena that are causing difficulty or have not been mastered, and (2) is also broad enough in scope to provide a credible and useful description of language proficiency.…

The first of four documents assesses the state of the art in the area of speech and language intervention for preschool handicapped children. It is explained in an introductory chapter that the report is designed to furnish an overview of existing programs and procedures which exemplify the field and identify critical issues which currently exist…

Bilingual and monolingual children were presented with experimental conditions where response mode and semantic information was varied. Forty children, 20 in each language-type group, responded in the present progressive and the past tenses to a series of colored drawings of simple activities. Half of the subjects responded to the task under…

In order to investigate the hypothesis that the conceptualization of sequence precedes that of simultaneity in child development, and to explore the use of elicited imitation in studying lexical acquisition, 32 subjects between 3 and 5 years of age were asked to verbally imitate a list of sentences. The constructions combined simple and reverse…

This report is a detailed empirical examination of Suppes' ideas about the syntax and semantics of natural language, and an attempt at supporting the proposal that model-theoretic semantics of the type first proposed by Tarski is a useful tool for understanding the semantics of natural language. Child speech was selected as the best place to find…

This paper presents some thoughts on teaching listening and speaking skills in second language learning. Both teacher and student roles are discussed along with learning devices. Teacher and student share active and productive roles in the development of listening and speaking skills; the breadth of each of their roles encompass both self-analysis…

This paper discusses the relationship of Polish to the other languages considered to be within the Slavic group. The comparison is mainly phonological and considers the Proto-Slavic features still preserved in Polish as well as the distinctive features of Polish which have developed from Proto-Slavic. The development of vowels and consonants is…

The notion of language dependency presupposes that there is a hierarchy of languages in a multilingual society, and that each language is assigned a functional role in a multilingual individual's restricted or extended spheres of linguistic interaction. In South Asia, language dependency has resulted in linguistic convergence of two types: (1)…

Twelve school-based speech-language practitioners enlisted the assistance of a university clinical phonologist to implement a research project investigating phonological acquisition. The speech samples of 520 children (ages 2-8) were transcribed. The 3-year-olds had acquired all major phoneme classes except liquids, /l/ was acquired between 4- 5,…

This article compares different claims that have been made concerning acquisition by transitional rule-based derivation theories and by optimality theory. Case studies of children with phonological delays are examined. Error patterns are argued to be implicationally related and optimality theory is shown to offer a principled explanation.…

The PLS-4 (Preschool Language Scale, 4th edition) is a psychometrically sound instrument constructed to assess language skills in children from birth to 6 years 11 months. It is a useful diagnostic and research tool that can be used to identify current comprehension and expressive language skills and can measure changes in language skills over…
