After decades of research most scholars generally agree that language acquisition is a complex and multifaceted process that involves the interaction of innate biologically-based mechanisms devoted to language, other non-linguistic cognitive and social mechanisms, linguistic input, and information about the social and physical world. Theoretical work in the field of language acquisition now needs to focus in greater depth and detail on some specific aspects of this general model, which is the main goal of this book. The chapters in this volume provide some new insights into one of the most remarkable accomplishments achieved by almost all children. The particular questions that are raised by contributors include: * What kinds of constraints operate on the process of language development? * Which aspects of the acquisition process depend on language-specific mechanisms? * Are there critical brain structures necessary for the acquisition of language? * What role do cognitive and social mechanisms play in language development? * How critical is perceptual input about the physical and social world? * What is the specific role played by linguistic input in the child's construction of a linguistic system? Questions are addressed from the perspective of children who come to the task of acquiring language with many hurdles to overcome, including deafness and blindness, mental retardation, autism, and prenatal or perinatal brain damage involving the left hemisphere. Each section contributes some insight on how an innate language-specific biological substrate interacts with cognitive and social factors, as well as external information, to support the child's construction of a linguistic system. Studies of atypical children offer a singular contribution to this enterprise by allowing us to see the specific influences of each component, and in turn, they shed new light on how all children are able to acquire language so effortlessly and during such a brief period of development.

This volume concerns various aspects of the theory and application of language conflict phenomena seen from an interdisciplinary perspective. The focus is on linguistic, social, psychological and educational issues (conditions, constraints and consequences) involved in the status and use of languages in multilingual settings. The book is divided into four sections, which deal with: theoretical issues - such as the nature of the concepts of language maintenance; language policy and language planning; attitudes towards languages; and codeswitching and language choice.

Sverker Johansson has written an unusual book on language origins, with its emphasis on empirical evidence rather than theory-building. This is a book for the student or researcher who prefers solid data and well-supported conclusions, over speculative scenarios. Much that has been written on the origins of language is characterized by hypothesizing largely unconstrained by evidence. But empirical data do exist, and the purpose of this book is to integrate and review the available evidence from all relevant disciplines, not only linguistics but also, e.g., neurology, primatology, paleoanthropology, and evolutionary biology. The evidence is then used to constrain the multitude of scenarios for language origins, demonstrating that many popular hypotheses are untenable. Among the issues covered: (1) Human evolutionary history, (2) Anatomical prerequisites for language, (3) Animal communication and ape "language", (4) Mind and language, (5) The role of gesture, (6) Innateness, (7) Selective advantage of language, (8) Proto-language.

This volume brings together cutting-edge experimental research from leaders in the fields of linguistics and psycholinguistics to explore the nature of a phenomenon that has long been central to syntactic theory - 'island effects'. The chapters in this volume draw upon recent methodological advances in experimental methods in syntax, also known as 'experimental syntax', to investigate the underlying cognitive mechanisms that give rise to island effects. This volume presents a comprehensive empirical review of a contemporary debate in the field by including contributions from researchers representing a variety of points of view on the nature of island effects. This book is ideal for students and researchers interested in cutting-edge experimental techniques in linguistics, psycholinguistics and psychology.

This book examines in detail the acceptability status of sentences in the following five English constructions, and elucidates the syntactic, semantic, and functional requirements that the constructions must satisfy in order to be appropriately used: There-Construction, (One’s) Way Construction, Cognate Object Construction, Pseudo-Passive Construction, and Extraposition from Subject NPs. It has been argued in the frameworks of Chomskyan generative grammar, relational grammar, conceptual semantics and other syntactic theories that the acceptability of sentences in these constructions can be accounted for by the unergative–unaccusative distinction of intransitive verbs. However, this book shows through a wide range of sentences that none of these constructions is sensitive to this distinction. For each construction, it shows that acceptability status is determined by a given sentence's semantic function as it interacts with syntactic constraints (which are independent of the unergative–unaccusative distinction), and with functional constraints that apply to it in its discourse context.

The progression from newborn to sophisticated language user in just a few short years is often described as wonderful and miraculous. What are the biological, cognitive, and social underpinnings of this miracle? What major language development milestones occur in infancy? What methodologies do researchers employ in studying this progression? Why do some become adept at multiple languages while others face a lifelong struggle with just one? What accounts for declines in language proficiency, and how might such declines be moderated? Despite an abundance of textbooks, specialized monographs, and a couple of academic handbooks, there has been no encyclopedic reference work in this area--until now. The Encyclopedia of Language Development covers the breadth of theory and research on language development from birth through adulthood, as well as their practical application. Features: This affordable A-to-Z reference includes 200 articles that address such topic areas as theories and research tradition; biological perspectives; cognitive perspectives; family, peer, and social influences; bilingualism; special populations and disorders; and more. All articles (signed and authored by key figures in the field) conclude with cross reference links and suggestions for further reading. Appendices include a Resource Guide with annotated lists of classic books and articles, journals, associations, and web sites; a Glossary of specialized terms; and a Chronology offering an overview and history of the field. A thematic Reader’s Guide groups related articles by broad topic areas as one handy search feature on the e-Reference platform, which includes a comprehensive index of search terms. Available in both print and electronic formats, Encyclopedia of Language Development is a must-have reference for researchers and is ideal for library reference or circulating collections. Key Themes: Categories Effects of language on cognitive development Fundamentals, theories and models of language development Impairments of language development Language development in special populations Literacy and language development Mechanisms of language development Methods in language development research Prelinguistic communicative development Social effects in language acquisition Specific aspects of language development

Shortlisted for the Christopher Brumfit Award in Applied Linguistics.The Development of the Grammatical System in Early Second Language Acquisition focuses on the acquisition process of early L2 learners. It is based on the following key hypothesis: the initial mental grammatical system of L2 learners is constrained semantically, syntactically and mnemonically. This hypothesis is formalised as the Multiple Constraints Hypothesis. The empirical test of the Multiple Constraints Hypothesis is based on a large database including cross-sectional and longitudinal data from square-one ESL beginners. The study demonstrates that the postulated constraints are relaxed successively as learning progresses. The book is intended for postgraduate students as well as SLA researchers.
