A study of first and second language development in an indigenous community with implications for broader linguistic and cognitive issues. When two or more languages are part of a child's world, we are presented with a rich opportunity to learn something about language in general and about how the mind works. In this book, Norbert Francis examines the development of bilingual proficiency and the different kinds of competence that come together in making up its component parts. In particular, he explores problems of language ability when children use two languages for tasks related to schooling, especially in learning how to read and write. He considers both broader research issues and findings from an ongoing investigation of child bilingualism in an indigenous language–speaking community in Mexico. This special sociolinguistic context allows for a unique perspective on some of the central themes of bilingualism research today, including the distinction between competence and proficiency, modularity, and the Poverty of Stimulus problem. Francis proposes that competence (knowledge) should be considered as an integral component of proficiency (ability) rather than something separate and apart, arguing that this approach allows for a more inclusive assessment of research findings from diverse fields of study. The bilingual indigenous language project illustrates how the concepts of modularity and the competence-proficiency distinction in particular might be applied to problems of language learning and literacy. Few investigations of indigenous language and culture approach bilingual research problems from a cognitive science perspective. By suggesting connections to broader cognitive and linguistic issues, Francis points the way to further research along these lines.

This practical and reassuring guide will enable readers to make informed decisions about how to raise their child bilingually.

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

This book sets a high standard for rigor and scientific approach to the study of bilingualism and provides new insights regarding the critical issues of theory and practice, including the interdependence of linguistic knowledge in bilinguals, the role of socioeconomic status, the effect of different language usage patterns in the home, and the role of schooling by single-language immersion as opposed to systematic training in both home and target languages. The rich landscape of outcomes reported in the volume will provide a frame for interpretation and understanding of effects of bilingualism for years to come.

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.

With contributions from an international team of leading experts, this volume offers new ways to explore and measure language dominance.
