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.

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.

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.

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.

Increasingly, children grow up hearing two languages from birth. This comprehensive textbook explains how children learn to understand and speak those languages. It brings together both established knowledge and the latest findings about different areas of bilingual language development. It also includes new analyses of previously published materials. The book describes how bilingually raised children learn to understand and use sounds, words and sentences in two languages. A recurrent theme is the large degree of variation between bilingual children. This variation in how children develop bilingually reflects the variation in their language learning environments. Positive attitudes from the people in bilingual children's language learning environments and their recognition that child bilingualism is not monolingualism-times-two are the main ingredients ensuring that children grow up to be happy and expert speakers of two languages.
