This Special Issue includes fifteen original state-of-the-art research articles from leading scholars that examine cross-linguistic influence in bilingual speech. These experimental studies contribute to the growing number of studies on multilingual phonetics and phonology by introducing novel empirical data collection techniques, sophisticated methodologies, and acoustic analyses, while also presenting findings that provide robust theoretical implications to a variety of subfields, such as L2 acquisition, L3 acquisition, laboratory phonology, acoustic phonetics, psycholinguistics, sociophonetics, blingualism, and language contact. These studies in this book further elucidate the nature of phonetic interactions in the context of bilingualism and multilingualism and outline future directions in multilingual phonetics and phonology research.

This book deals with the phenomenon of third language (L3) acquisition. As a research field, L3 acquisition is established as a branch of multilingualism that is concerned with how multilinguals learn additional languages and the role that their multilingual background plays in the process of language learning. The volume points out some current directions in this particular research area with a number of studies that reveal the complexity of multilingual language learning and its typical variation and dynamics. The eight studies gathered in the book represent a wide range of theoretical positions and offer empirical evidence from learners belonging to different age groups, and with varying levels of proficiency in the target language, as well as in other non-native languages belonging to the learner’s repertoire. Diverse linguistic phenomena and language combinations are viewed from a perspective where all previously acquired languages have a potential role to play in the process of learning a new language. In the six empirical studies, contexts of language learning in school or at university level constitute the main outlet for data collection. These studies involve several language backgrounds and language combinations and focus on various linguistic features. The specific target languages in the empirical studies are English, French and Italian. The volume also includes two theoretical chapters. The first one conceptualizes and describes the different types of multilingual language learning investigated in the volume: i) third or additional language learning by learners who are bilinguals from an early age, and ii) third or additional language learning by people who have previous experience of one or more non-native languages learned after the critical period. In particular, issues related to the roles played by age and proficiency in multilingual acquisition are discussed. The other theoretical chapter conceptualizes the grammatical category of aspect, reviewing previous studies on second and third language acquisition of aspect. Different models for L3 learning and their relevance and implications for representations of aspect and for potential differences in the processing of second and third language acquisition are also examined in this chapter. As a whole, the book presents current research into third or additional language learning by young learners or adults, considering some of the most important factors for the complex process of multilingual language learning: the age of onset of the additional language and that of previously acquired languages, social and affective factors, instruction, language proficiency and literacy, the typology of the background languages and the role they play in shaping syntax, lexicon, and other components of a L3. The idea for this book emanates from the symposium Multilingualism, language proficiency and age, organized by Camilla Bardel and Laura Sánchez at Stockholm University, Department of Language Education, in December 2016.

Including contributions from a team of world-renowned international scholars, this volume is a state-of-the-art survey of second language speech research, showcasing new empirical studies alongside critical reviews of existing influential speech learning models. It presents a revised version of Flege's Speech Learning Model (SLM-r) for the first time, an update on a cornerstone of second language research. Chapters are grouped into five thematic areas: theoretical progress, segmental acquisition, acquiring suprasegmental features, accentedness and acoustic features, and cognitive and psychological variables. Every chapter provides new empirical evidence, offering new insights as well as challenges on aspects of the second language speech acquisition process. Comprehensive in its coverage, this book summarises the state of current research in second language phonology, and aims to shape and inspire future research in the field. It is an essential resource for academic researchers and students of second language acquisition, applied linguistics and phonetics and phonology.

Multiculturalism is a prevalent worldwide societal phenomenon. Aspects of our modern life, such as migration, economic globalization, multicultural policies, and cross-border travel and communication have made intercultural contacts inevitable. High numbers of multicultural individuals (23-43% of the population by some estimates) can be found in many nations where migration has been strong (e.g., Australia, U.S., Western Europe, Singapore) or where there is a history of colonization (e.g., Hong Kong). Many multicultural individuals are also ethnic and cultural minorities who are descendants of immigrants, majority individuals with extensive multicultural experiences, or people with culturally mixed families; all people for whom identification and/or involvement with multiple cultures is the norm. Despite the prevalence of multicultural identity and experiences, until the publication of this volume, there has not yet been a comprehensive review of scholarly research on the psychological underpinning of multiculturalism. The Oxford Handbook of Multicultural Identity fills this void. It reviews cutting-edge empirical and theoretical work on the psychology of multicultural identities and experiences. As a whole, the volume addresses some important basic issues, such as measurement of multicultural identity, links between multilingualism and multiculturalism, the social psychology of multiculturalism and globalization, as well as applied issues such as multiculturalism in counseling, education, policy, marketing and organizational science, to mention a few. This handbook will be useful for students, researchers, and teachers in cultural, social, personality, developmental, acculturation, and ethnic psychology. It can also be used as a source book in advanced undergraduate and graduate courses on identity and multiculturalism, and a reference for applied psychologists and researchers in the domains of education, management, and marketing.

Given the differences in the orthographic structure of the Uyghur, Chinese and English languages, this study used a mixed-method approach to systematically describe and analyze the phonological awareness of Uyghur bilingual children as English learners and its contributions to their trilingual literacy acquisition and development. Focusing on the development of these learners' phonological awareness in Uyghur, Chinese and English, this study explored the influences of Uyghur and Chinese learning on the formation of their English phonological awareness and the roles of different components of phonological awareness in their trilingual literacy development. Based on the characteristics of the phonetic structure in Uyghur, Chinese and English and the development of Uyghur children's phonological awareness in these languages, a Chinese phonetic identification training and Uyghur–Chinese–English comprehensive phonetic training program (including intensive phoneme category contrast training and phonics training) was designed to explore whether such targeted phonetic identification training can effectively improve these children's phonological awareness in Chinese and English and thus further promote their trilingual literacy development. This book will appeal to researchers and students interested in the fields of psycholinguistics, language acquisition and multilingual education.

A cogent, freshly written synthesis of new and classic work on crosslinguistic influence, or language transfer, this book is an authoritative account of transfer in second-language learning and its consequences for language and thought. It covers transfer in both production and comprehension, and discusses the distinction between semantic and conceptual transfer, lateral transfer, and reverse transfer. The book is ideal as a text for upper-level undergraduate and graduate courses in bilingualism, second language acquisition, psycholinguistics, and cognitive psychology, and will also be of interest to researchers in these areas.

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.
