This book "supplies a vocabulary of English words and idiomatic phrases 'arranged … according to the ideas which they express'. The thesaurus, continually expanded and updated, has always remained in print, but this reissued first edition shows the impressive breadth of Roget's own knowledge and interests."
This introductory guide to language acquisition research is presented within the framework of Universal Grammar, a theory of the human faculty for language. The authors focus on two experimental techniques for assessing childrens linguistic competence: the Elicited Production task, a production task, and the Truth Value Judgment task, a comprehension task. Their methodologies are designed to overcome the numerous obstacles to empirical investigation of childrens language competence. They produce research results that are more reproducible and less likely to be dismissed as an artifact of improper experimental procedure. In the first section of the book, the authors examine the fundamental assumptions that guide research in this area; they present both a theory of linguistic competence and a model of language processing. In the following two sections, they discuss in detail their two experimental techniques.
