This book presents a comprehensive, state-of-the-art treatment of the acquisition of Indo- and Non-Indo-European languages in various contexts, such as L1, L2, L3/Ln, bi/multilingual, heritage languages, pathology as well as language impairment, and sign language acquisition. The book explores a broad mix of methodologies and issues in contemporary research. The text presents original research from several different perspectives, and provides a basis for dialogue between researchers working on diverse projects with the aim of furthering our understanding of how languages are acquired. The book proposes and refines new theoretical constructs, e.g. regarding the complexity of linguistic features as a relevant factor forming children’s, adults’ and bilingual individuals’ acquisition of morphological, syntactic, discursive, pragmatic, lexical and phonological structures. It appeals to students, researchers, and professionals in the field.

This volume presents recent generative research on the nature of grammars of child second language (L2) acquirers -- a learner population whose exposure to an L2 occurs between the ages of 4 to 8. The main goal is to define child L2 acquisition in relation to other types of acquisition such as child monolingual and bilingual acquisition, adult L2 acquisition, and specific language impairment. This comparative perspective opens up new angles for the discussion of currently debated issues such as the role of Universal Grammar in constraining development, developmental sequences in L2, maturational influences on the 'growth' of grammar, critical period effects for different linguistic domains, initial state and ultimate attainment in relation to length of exposure, and L1-transfer in relation to age of onset. These issues are explored using longitudinal, cross-sectional, and experimental data from L2 children acquiring a range of languages, including Dutch, English, French, and Greek.

The purpose of this book is to present recent studies in the field of multilingualism and L3, bringing together contributions from an international group of specialists from Austria, Canada, Germany, Portugal, Spain, Switzerland, Turkey, and United States. The main focuses of the articles are three: language acquisition, language learning and teaching. A collection of theoretical and empirical articles from scholars of multilingualism and language acquisition makes the book a significant resource as the papers present a wide perspective from main theories to current issues, reflecting new trends in the field. The authors focus on the heterogeneity and complexity that characterize third language acquisition, multilingual learning and teaching. As the issues addressed in this book intersect, it represents an asset and therefore the texts will be of great relevance for the scientific community. Part I presents different topics of L3 acquisition, such as syntax, phonology, working memory and selective attention, and lexicon. Part II comprises texts that show how the research on language acquisition informs pedagogical issues. For instance, the role of the knowledge of previous languages in the teaching of L3, the attitudes of multilingual teachers to plurilingual approaches, and the benefits of crosslinguistic pedagogy versus classroom monolingual bias. In sequence, Part III consists of texts on individual learning strategies, such as motivation and attitudes, crosslinguistic awareness, and students’ perceptions about teachers’ “plurilingual nonnativism”. All these chapters include several different languages in contact in an acquisition/learning context: Basque, English, French, German, Italian, Ladin, Portuguese, Russian, Spanish, and Turkish.

In our increasingly multilingual modern world, understanding how languages beyond the first are acquired and processed at a brain level is essential to design evidence-based teaching, clinical interventions and language policy. Written by a team of world-leading experts in a wide range of disciplines within cognitive science, this Handbook provides a comprehensive overview of the study of third (and more) language acquisition and processing. It features 30 approachable chapters covering topics such as multilingual language acquisition, education, language maintenance and language loss, multilingual code-switching, ageing in the multilingual brain, and many more. Each chapter provides an accessible overview of the state of the art in its topic, while offering comprehensive access to the specialized literature, through carefully curated citations. It also serves as a methodological resource for researchers in the field, offering chapters on methods such as case studies, corpora, artificial language systems or statistical modelling of multilingual data.

This series offers a wide forum for work on contact linguistics, using an integrated approach to both diachronic and synchronic manifestations of contact, ranging from social and individual aspects to structural-typological issues. Topics covered by the series include child and adult bilingualism and multilingualism, contact languages, borrowing and contact-induced typological change, code switching in conversation, societal multilingualism, bilingual language processing, and various other topics related to language contact. The series does not have a fixed theoretical orientation, and includes contributions from a variety of approaches.
