This book provides a snapshot of the field of language acquisition at the beginning of the 21st Century. It represents the multiplicity of approaches that characterize the field and provides a review of current topics and debates, as well as addressing some of the connections between sub-fields and possible future directions for research.

Cognitive Development and Acquisition of Language

An introduction to the study of children's language development that provides a uniquely accessible perspective on generative/universal grammar–based approaches. How children acquire language so quickly, easily, and uniformly is one of the great mysteries of the human experience. The theory of Universal Grammar suggests that one reason for the relative ease of early language acquisition is that children are born with a predisposition to create a grammar. This textbook offers an introduction to the study of children's acquisition and development of language from a generative/universal grammar–based theoretical perspective, providing comprehensive coverage of children's acquisition while presenting core concepts crucial to understanding generative linguistics more broadly. After laying the theoretical groundwork, including consideration of alternative frameworks, the book explores the development of the sound system of language—children's perception and production of speech sound; examines how words are learned (lexical semantics) and how words are formed (morphology); investigates sentence structure (syntax), including argument structure, functional structure, and tense; considers such “nontypical” circumstances as acquiring a first language past infancy and early childhood, without the abilities to hear or see, and with certain cognitive disorders; and studies bilingual language acquisition, both simultaneously and in sequence. Each chapter offers a summary section, suggestions for further reading, and exercises designed to test students' understanding of the material and provide opportunities to practice analyzing children's language. Appendixes provide charts of the International Phonetic Alphabet (with links to websites that allow students to listen to the sounds associated with these symbols) and a summary of selected experimental methodologies.

Sheds light on the what, why, and how of the child's ability to acquire one or more languages. This handbook includes treatments of acquisition from a variety of viewpoints, ranging from functionalist approaches and the implications of the creolization of languages for the study of acquisition, to the relevance of Chomsky's Minimalist Program.

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?

Taking an accessible and cross-linguistic approach, Understanding Child Language Acquisition introduces readers to the most important research on child language acquisition over the last fifty years, as well as to some of the most influential theories in the field. Rather than just describing what children can do at different ages Rowland explains why these research findings are important and what they tell us about how children acquire language. Key features include: Cross-linguistic analysis of how language acquisition differs between languages A chapter on how multilingual children acquire several languages at once Exercises to test comprehension Chapters organised around key questions that summarise the critical issues posed by researchers in the field, with summaries at the end Further reading suggestions to broaden understanding of the subject With its particular focus on outlining key similarities and differences across languages and what this cross-linguistic variation means for our ideas about language acquisition, Understanding Child Language Acquisition forms a comprehensive introduction to the subject for students of linguistics, psychology and speech and language therapy. Students and instructors will benefit from the comprehensive companion website that includes a students’ section featuring interactive comprehension exercises, extension activities, chapter recaps and answers to the exercises within the book. Material for instructors includes sample essay questions, answers to the extension activities for students and a Powerpoint including all the figures from the book. www.routledge.com/cw/rowland

In recent years the field has seen an increasing realisation that the full complexity of language acquisition demands theories that (a) explain how children integrate information from multiple sources in the environment, (b) build linguistic representations at a number of different levels, and (c) learn how to combine these representations in order to communicate effectively. These new findings have stimulated new theoretical perspectives that are more centered on explaining learning as a complex dynamic interaction between the child and her environment. This book is the first attempt to bring some of these new perspectives together in one place. It is a collection of essays written by a group of researchers who all take an approach centered on child-environment interaction, and all of whom have been influenced by the work of Elena Lieven, to whom this collection is dedicated.
