This dissertation presents a series of case studies concerned with whether the signal in a given set of measurements that we take in the course of linguistic inquiry reflects grammatical competence or performance factors. We know that performance and competence do not always covary, yet it is not uncommon to assume that measurements that we take…

In the 1980s, researchers in child language devised several new experimental techniques to assess children's emerging linguistic competence. Innovations in methodology were needed to bridge the apparent gap between the expectation of rapid language acquisition, based on linguistic theory, and the protracted acquisition that was being witnessed…

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…

In a study extending and refining Carol Chomsky's research, 48 Arabic speaking children aged six, eight, and ten were tested for their comprehension of imperatives using the complement-requiring verbs Ask, Tell, and Promise. Clear support for children's overgeneralization of the minimal distance principle was found only with Promise constructions.…

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 paper reports on a study conducted to determine the abilities of children to make optional transformations in sentences conjoined with "and." The subjects were 35 middle-class children between the ages of five and eight, who demonstrated average school achievement, spoke standard American English, and had normal speech and hearing. A…

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)

Examines the innate faculties that underlie linguistic competence, especially syntactic competence, and proposes a theory of these faculties which accounts for the complexities of language and the evolution of human language. (AM)

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 paper attempts to specify the ways in which bilingualism might affect cognitive functioning. Two general ways, the "linguistic" and the "non-linguistic," are distinguished. Linguistic explanations explain the effects of bilingualism on cognition as a direct result of the fact that the bilingual has access to two verbal…

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…
