Infants and very young children develop almost miraculously the ability of speech, without apparent effort, without even being taught - as opposed to the teenager or the adult struggling without, it seems, ever being able to reach the same level of proficiency as five year olds in their first language. This useful textbook serves as a guide to different types of language acquisition: monolingual and bilingual first language development and child and adult second language acquisition. Unlike other books, it systematically compares first and second language acquisition, drawing on data from several languages. Research questions and findings from various subfields are helpfully summarized to show students how they are related and how they often complement each other. The essential guide to studying first and second language acquisition, it will be used on courses in linguistics, modern languages and developmental psychology.

This new volume of work highlights the distinctiveness of child SLA through a collection of different types of empirical research specific to younger learners. Characteristics of children’s cognitive, emotional, and social development distinguish their experiences from those of adult L2 learners, creating intriguing issues for SLA research, and also raising important practical questions regarding effective pedagogical techniques for learners of different ages. While child SLA is often typically thought of as simple (and often enjoyable and universally effortless), in other words, as “child’s play”, the complex portraits of young second language learners which emerge in the 16 papers collected in this book invite the reader to reconsider the reality for many younger learners. Chapters by internationally renowned authors together with reports by emerging researchers describe second and foreign language learning by children ranging from pre-schoolers to young adolescents, in home and school contexts, with caregivers, peers, and teachers as interlocutors.

This book is a thorough revision of the highly successful text first published in 1994. The authors retain the multidisciplinary approach that presents research from linguistics, sociology, psychology, and education, in a format designed for use in an introductory course for undergraduate or graduate students. The research is updated throughout and there are new sections and chapters in this second edition as well. New chapters cover child language acquisition (first and second), Universal Grammar, and instructed language learning; new sections address issues, such as what data analysis doesn't show, replication of research findings, interlanguage transfer (multilingual acquisition and transfer), the aspect hypothesis, general nativism, connectionist approaches, and implicit/explicit knowledge. Major updates include nonlanguage influences and the lexicon. The workbook, Second Language Learning Data Analysis, Second Edition, makes an ideal accompaniment to the text.

A clear and practical introduction to second language acquisition, written for students encountering the topic for the first time.

Whether we grow up with one, two, or several languages during our early years of life, many of us will learn a second, foreign, or heritage language in later years. The field of Second language acquisition (SLA, for short) investigates the human capacity to learn additional languages in late childhood, adolescence, or adulthood, after the first language --in the case of monolinguals-- or languages --in the case of bilinguals-- have already been acquired. Understanding Second Language Acquisition offers a wide-encompassing survey of this burgeoning field, its accumulated findings and proposed theories, its developed research paradigms, and its pending questions for the future. The book zooms in and out of universal, individual, and social forces, in each case evaluating the research findings that have been generated across diverse naturalistic and formal contexts for second language acquisition. It assumes no background in SLA and provides helpful chapter-by-chapter summaries and suggestions for further reading. Ideal as a textbook for students of applied linguistics, foreign language education, TESOL, and education, it is also recommended for students of linguistics, developmental psycholinguistics, psychology, and cognitive science.

This volume is a collection of 13 chapters, each devoted to a particular issue that is crucial to our understanding of the way learners acquire, learn, and use an L2 sound system. In addition, it spans both theory and application in L2 phonology. The book is divided into three parts, with each section unified by broad thematic content: Part I, “Theoretical Issues and Frameworks in L2 Phonology,” lays the groundwork for examining L2 phonological acquisition. Part II, “Second Language Speech Perception and Production,” examines these two aspects of L2 speech in more detail. Finally, Part III, “Technology, Training, and Curriculum,” bridges the gap between theory and practice. Each chapter examines theoretical frameworks, major research findings (both classic and recent), methodological issues and choices for conducting research in a particular area of L2 phonology, and major implications of the research findings for more general models of language acquisition and/or pedagogy.

Second Language Acquisition and the Critical Period Hypothesis is the only book on the market to provide a diverse collection of perspectives, from experienced researchers, on the role of the Critical Period Hypothesis in second language acquisition. It is widely believed that age effects in both first and second language acquisition are developmental in nature, with native levels of attainment in both to be though possible only if learning began before the closure of a "window of opportunity" – a critical or sensitive period. These seven chapters explore this idea at length, with each contribution acting as an authoritative look at various domains of inquiry in second language acquisition, including syntax, morphology, phonetics/phonology, Universal Grammar, and neurofunctional factors. By presenting readers with an evenly-balanced take on the topic with viewpoints both for and against the Critical Period Hypothesis, this book is the ideal guide to understanding this critical body of research in SLA, for students and researchers in Applied Linguistics and Second Language Acquisition.
