Language acquisition is a human endeavor par excellence. As children, all human beings learn to understand and speak at least one language: their mother tongue. It is a process that seems to take place without any obvious effort. Second language learning, particularly among adults, causes more difficulty. The purpose of this series is to compile a collection of high-quality monographs on language acquisition. The series serves the needs of everyone who wants to know more about the problem of language acquisition in general and/or about language acquisition in specific contexts.

Leading scholars examine the relationship between child language acquisition and cognitive development.

Do all children learn language in the same way? Is the apparent "fast" vs. "slow" language learning rate among children a reflection of the individual child′s approach to language acquisition? This volume explores the importance that individual differences have in acquiring language and challenges some of the widely held theories of linguistic development. Focusing on children ages one to three, the author describes characteristic differences in terms of vocabulary, grammatical, and phonological development, and considers whether distinctive "styles" of language development can be defined. In addition, the social and cognitive influences that can explain these differences are examined. The book concludes with a look at new language theories such as ecological, chaos, and connectionist approaches and considers what individual differences in development can tell us about the mechanisms of language development. Individual Differences in Language Development is invaluable for professionals and researchers in developmental psychology, family studies, education, psychology, and communication. "Cecilia M. Shore puts forward an alternative theory on differences in language development and offers an important message on the significance of context in children′s early language acquisition. The principal theme has significant implications for further research as well as practical implications for teacher trainers, teachers and parents." --Durante′s "Cecilia M. Shore writes in a warm and engaging style. . . . It serves her purpose well: to put across complex ideas in a clear and unforgettable form. . . . The content is right on target. Shore covers all the relevant issues in this complex area, and her review is right up to date." --Elizabeth Bates, Professor of Psychology and Professor of Cognitive Science, University of California, San Diego

This book presents a current, interdisciplinary perspective on language requisites from both a biological/comparative perspective and from a developmental/learning perspective. Perspectives regarding language and language acquisition are advanced by scientists of various backgrounds -- speech, hearing, developmental psychology, comparative psychology, and language intervention. This unique volume searches for a rational interface between findings and perspectives generated by language studies with humans and with chimpanzees. Intended to render a reconsideration as to the essence of language and the requisites to its acquisition, it also provides readers with perspectives defined by various revisionists who hold that language might be other than the consequence of a mutation unique to humans and might, fundamentally, not be limited to speech.

Ever since attempts were made to describe and explain normal language development, references to exceptional circumstances have been made. Variations in the conditions under which language is acquired can be regarded as natural experiments, which would not be feasible or ethical under normal circumstances. This can throw light on such questions as: *What language input is necessary for the child to learn language? *What is the relationship between cognition and language? *How independent are different components of language function? *Are there critical periods for language development? *Can we specify necessary and sufficient conditions for language impairment? This book covers a range of exceptional circumstances including: extreme deprivation, twinship, visual and auditory impairments, autism and focal brain damage? Written in a jargon-free style, and including a glossary of linguistic and medical terminology, the book assumes little specialist knowledge. This text is suitable for both students and practitioners in the fields of psycholinguistics, developmental and educational psychology, speech pathology, paediatrics and special education.

The study of language acquisition has become a center of scientific inquiry into the nature of the human mind. The result is a windfall of new information about language, about learning, and about children themselves. In Language Acquisition Jill and Peter de Villiers provide a lively introduction to this fast-growing field. Their book deals centrally with the way the child acquires the sounds, meanings, and syntax of his language, and the way he learns to use his language to communicate with others. In discussing these issues, the de Villiers provide a clear and insightful treatment of the classic questions about language acquisition: Does the child show a genetic predisposition for speech, or grammar, or semantics which makes him uniquely able to learn human language? What kinds of learning are involved in acquiring language and what kinds of experience with a language are necessary to support such learning? Is there a critical period during the child's development which is optimal for language acquisition? And what kind of psychological disabilities underlie the failure to acquire language?
