The present volume reflects the proceedings of the fourth annual symposium at the Carnegie-Mellon University, which dealt with developmental linguistics in general and with child language acquisition in particular. Contents include an Introduction by John R. Hayes; "Derivational Complexity and Order of Acquisition in Child Speech," by R. Brown and…

The conditions whereby a concept might be learned on the basis of a language mediation process prior to the inductive learning of subordinate concepts are sketched. The view is expressed that grammar treatments which are apt to primary education should be defined on the basis of a pedagogy's needs for linguistic characterizations of concepts to be…

This paper reviews work done since January 1972 in children's language acquisition and development. It is divided into the following sections: (1) a brief summary of descriptive studies of adult and child speech, (2) a review of the results of three types of manipulative studies, and (3) a discussion of J. Gruber's interpretation of early…

The arguments for and against viewing the child's initial one-word utterances as holophrases are reviewed. An alternative view of early language development, which takes the speech act as the basic unit of linguistic communication, rather than the sentence, is offered as a solution to the holophrase controversy.

The discussion throughout this paper is devoted to answering the question: What is the nature of our knowledge of language and what theoretical assumptions does the answer entail for linguistic description? Discussed are--(1) what it means to know a language, (2) the distinction between linguistic competence and performance, (3) justification of…

This collection of studies is divided into four parts. Part one is concerned with aspects of maternal communication as it relates to regulative and instructional contexts. Part two focuses on aspects of the speech of five year olds, with Hawkins examining choices within the nominal group, Turner and Pickvance examining expressions of uncertainty…

Earlier version of this article was presented at the 43rd Annual Meeting of the Linguistic Society of America, December 28, 1968. (VM)

Type of discourse and syntax are related; speech researchers will have to specify type of discourse for their results to be comparable with other studies. (JH)

Previous studies dealing with the age at which children acquire constituent order preferences have been in conflict. This study was designed to determine if children with normal language development demonstrate constituent order preferences as early as age three and one-half, or a mean age of four years, one month. To test this competency, an…

Some of the assertions made by Chomsky in "Aspects of the Theory of Syntax" are considered. In particular, the notion of a "competence" model in linguistics is criticized. Formal postulates for a conceptually-based linguistic theory are presented. (Author/JD)

This conference report is centered on that phase of the Targeted Research and Development Program in Reading literature search dealing with language development as it relates to reading. Models of language acquisition, hypotheses derived from the models, and comparisons of synthesized models are discussed. Among them are behaviorist (Skinner),…

A question of both theoretical and practical importance for the study of phonological development is whether there is a difference in the status of productions rendered spontaneously by the child and those repeated by the child after either an adult model or his own production. The relevant theoretical questions are: (1) Are all the child's…

A study was conducted to examine syntactical development in spontaneous written language of selected preschool, kindergarten and first grade children. The two major experimental questions were: (1) Will there be development towards greater complexity in the syntax of spontaneous writing and how should it be described? (2) What transformational…

This book describes how the child acquires a linguistic system before he is capable of verbal utterances or has developed the ability to structure language in a meaningful way. The first chapter of the book contains a discussion of previous language development studies on learning the mother tongue and proposes a hypothesis of language development…
