This volume is the outcome of the author s observations and puzzlement over seventeen years of teaching English and French as second languages, followed by 30 years of research into the neurolinguistic aspects of bilingualism. It examines, within the framework of a neurolinguistic theory of bilingualism (Paradis, 2004), the crucial and pervasive contributions made by declarative and procedural memory to the appropriation, representation and processing of a second language. This requires careful consideration of a number of concepts associated with issues pertaining to second language research: consciousness, interface, modularity, automaticity, proficiency, accuracy, fluency, intake, ultimate attainment, switching, implicit linguistic competence and explicit metalinguistic knowledge. It is informed by data from a variety of domains, including language pathology, neuroimaging, and, from each side of the fence, practical classroom experience. This book introduces four further proposals within the framework of a neurolinguistic theory of bilingualism: (1) There are two sets of cerebral representations, those that are capable of reaching consciousness and those that are not; implicit grammar is inherently not capable of reaching consciousness. (2) The increased activation observed in neuroimaging studies during the use of a second language is not devoted to the processing of implicit linguistic competence. (3) Intake is doubly implicit. (4) Given the premise that metalinguistic knowledge cannot be converted into implicit competence, there can be no possible interface between the two."

The Routledge Handbook of Second Language Acquisition and Psycholinguistics provides a comprehensive survey of the latest research at the intersection of linguistics, cognitive psychology, and applied linguistics, for those seeking to understand the mental architecture and processes that shape the acquisition of additional languages. The handbook represents the full complexity of second language acquisition across the lifespan, spanning childhood bilinguals and adult L2 learners, and is inclusive of heritage languages, early bilingualism and multilingualism, and language attrition. An authoritative selection of diverse, global, leading psycholinguists synthesize the latest research to provide a thorough overview in a single volume and set the agenda for the future. The volume is organized into five key parts for ease of use: psycholinguistics across the lifespan; methods; theoretical perspectives; the psycholinguistics of learning; and transdisciplinary perspectives. This handbook will be an indispensable resource for scholars and students of psycholinguistics, second language acquisition, applied linguistics, bilingualism, cognitive science, psychology, and research methodology.

The second edition of Theories in Second Language Acquisition seeks to build on the strengths of the first edition by surveying the major theories currently used in second language acquisition research. This volume is an ideal introductory text for undergraduate and graduate students in SLA and language teaching. Each chapter focuses on a single theory, written by a leading scholar in the field in an easy-to-follow style – a basic foundational description of the theory, relevant data or research models used with this theory, common misunderstandings, and a sample study from the field to show the theory in practice. This text is designed to provide a consistent and coherent presentation for those new to the field who seek basic understanding of theories that underlie contemporary SLA research. Researchers will also find the book useful as a "quick guide" to theoretical work outside their respective domains.

The Routledge Handbook of Instructed Second Language Acquisition is the first collection of state-of-the-art papers pertaining to Instructed Second Language Acquisition (ISLA). Written by 45 world-renowned experts, the entries are full-length articles detailing pertinent issues with up-to-date references. Each chapter serves three purposes: (1) provide a review of current literature and discussions of cutting edge issues; (2) share the authors’ understanding of, and approaches to, the issues; and (3) provide direct links between research and practice. In short, based on the chapters in this handbook, ISLA has attained a level of theoretical and methodological maturity that provides a solid foundation for future empirical and pedagogical discovery. This handbook is the ideal resource for researchers, graduate students, upper-level undergraduate students, teachers, and teacher-educators who are interested in second language learning and teaching. .

Language Aptitude: Advancing Theory, Testing, Research and Practice brings together cutting-edge global perspectives on foreign language aptitude. Drawing from educational psychology, cognitive science, and neuroscience, the editors have assembled interdisciplinary authors writing for an applied linguistics and education audience. The book is broken into five major themes: revisiting and updating current language aptitude theories and models; emerging insights from contemporary research into language aptitude and the age factor or the critical period hypothesis; redefining constructs and broadening territories of foreign language aptitude; exploring language aptitude from a neurocognitive perspective; and exploring future directions of foreign language aptitude research. Focused on critical issues in foreign language aptitude and second language learning and teaching, this book will be an important research resource and supplemental reading in both applied linguistics and cognitive psychology.
