Children acquiring two languages, either simultaneously or sequentially, have more variation in their linguistic input than their monolingual peers. Understanding the nature and consequences of this variability has been the focus of much recent research on childhood bilingualism. This volume constitutes the first collection of research solely dedicated to the topic of input in childhood bilingualism. Chapters represent a range of theoretical and methodological approaches to the study of childhood bilingualism, covering a variety of language combinations and sociocultural contexts in Europe, Israel, North and South America. As a reflection of the field’s current understanding of the intricate relationship between experience and development in children growing up with two or more languages, this volume will be of interest to scholars and practitioners working with bi- and multilingual learners in various sociolinguistic and educational contexts.

The ability to speak two or more languages is a common human experience, whether for children born into bilingual families, young people enrolled in foreign language classes, or mature and older adults learning and using more than one language to meet life's needs and desires. This Handbook offers a developmentally oriented and socially contextualized survey of research into individual bilingualism, comprising the learning, use and, as the case may be, unlearning of two or more spoken and signed languages and language varieties. A wide range of topics is covered, from ideologies, policy, the law, and economics, to exposure and input, language education, measurement of bilingual abilities, attrition and forgetting, and giftedness in bilinguals. Also explored are cross- and intra-disciplinary connections with psychology, clinical linguistics, second language acquisition, education, cognitive science, neurolinguistics, contact linguistics, and sign language research.

This book pioneers the study of bilingualism across the lifespan and in all its diverse forms. In framing the newest research within a lifespan perspective, the editors highlight the importance of considering an individual's age in researching how bilingualism affects language acquisition and cognitive development. A key theme is the variability among bilinguals, which may be due to a host of individual and sociocultural factors, including the degree to which bilingualism is valued within a particular context.Thus, this book is a call for language researchers, psychologists, and educators to pursue a better understanding of bilingualism in our increasingly global society.

In the first decade of life, children become bilingual in different language learning environments. Many children start learning two languages from birth (Bilingual First Language Acquisition). In early childhood hitherto monolingual children start hearing a second language through daycare or preschool (Early Second Language Acquisition). Yet other hitherto monolingual children in middle childhood may acquire a second language only after entering school (Second Language Acquisition). This Element explains how these different language learning settings dynamically affect bilingual children's language learning trajectories. All children eventually learn to speak the societal language, but they often do not learn to fluently speak their non-societal language and may even stop speaking it. Children's and families' harmonious bilingualism is threatened if bilingual children do not develop high proficiency in both languages. Educational institutions and parental conversational practices play a pivotal role in supporting harmonious bilingual development.

An authoritative overview of research into heritage language acquisition, covering key terminological and empirical issues, theoretical approaches, and research methodologies.

In this accessible guide to bilingualism in the family and the classroom, Colin Baker delivers a realistic picture of the joys and difficulties of raising bilingual children. This revised edition includes more information on bilingualism in the digital age, and incorporates the latest research in areas such as neonatal language experience, multilingualism and language mixing.

This book contains reports of research on bilingualism in infants and children as well as perspectives from those involved in cross-linguistic research on language development, literacy development in bilingual children, and psycholinguistic research on bilingualism in adults. It offers a fresh multidisciplinary perspective and next steps for research on childhood bilingualism.

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.

How do children develop bilingual competence? Do bilingual children develop language in the same way as monolinguals? Set in the context of findings on language development, this book examines the acquisition of English and Spanish by two brothers in the first six years of their lives. Based on in-depth and meticulous analyses of naturalistic data, it explores how the systems of both languages affect each other as the children develop, and how different levels of exposure to each language influence the nature of acquisition. The author demonstrates that the children's grammars and lexicons follow a developmental path similar to that of monolinguals, but that cross-linguistic interactions affecting lexical, semantic and discourse-pragmatic aspects arise in Spanish when exposure to it diminishes around the age of four. The first of its kind, this original study is a must-read for students and researchers in bilingualism, child development, language acquisition and language contact.
