Is children's language acquisition based on innate linguistic structures or built from cognitive and communicative skills? This book summarises the major theoretical debates in all of the core domains of child language acquisition research (phonology, word-learning, inflectional morphology, syntax and binding) and includes a complete introduction to the two major contrasting theoretical approaches: generativist and constructivist. For each debate, the predictions of the competing accounts are closely and even-handedly evaluated against the empirical data. The result is an evidence-based review of the central issues in language acquisition research that will constitute a valuable resource for students, teachers, course-builders and researchers alike.

This volume presents original up-to-date research in the field of language acquisition. The contributions reflect experimental work guided by linguistic theory, covering different populations of learners, a wide range of linguistic phenomena, a variety of empirical methods, and a rich set of typologically different languages. The studies investigate first and second language acquisition, as well as acquisition in children with developmental language disorder or hearing impairment. The different chapters address various phenomena in the areas of morpho-syntax, phonology, and semantics. This edited collection of papers is a valuable reference for researchers who are interested in language acquisition research and its multifaceted nature. The book highlights the fruitful connection between empirical research and linguistic theory, making it interesting to both psycholinguists and theoretical linguists. The experimental studies collected in this book contribute to our understanding of how different types of learners acquire and process language and can offer novel insights to theoretical linguistics as well.

What is language and how can we investigate its acquisition by children or adults? What perspectives exist from which to view acquisition? What internal constraints and external factors shape acquisition? What are the properties of interlanguage systems? This comprehensive 31-chapter handbook is an authoritative survey of second language acquisition (SLA). Its multi-perspective synopsis on recent developments in SLA research provides significant contributions by established experts and widely recognized younger talent. It covers cutting edge and emerging areas of enquiry not treated elsewhere in a single handbook, including third language acquisition, electronic communication, incomplete first language acquisition, alphabetic literacy and SLA, affect and the brain, discourse and identity. Written to be accessible to newcomers as well as experienced scholars of SLA, the Handbook is organised into six thematic sections, each with an editor-written introduction.

The mental representation of language cannot be directly observed but must be inferred and modelled from its effects at second hand. Linguists have traditionally responded to this in two ways, either going for a fairly data-light approach and valuing theoretical creativity, or pursuing just those goals for which data is available and trusting to data-driven descriptive work. More recently, advances in technology and experimental techniques have made data gathering easier and more accessible, so that a theoretically informed but empirically based approach is rapidly growing in popularity. This synthesis permits linguists to combine the intellectual hypothesis generation of the theoreticians with the ability to deliver hard answers of the empiricist. This volume is a collection of papers in this direction, using mostly experiment methods to yield insights into syntactic and semantic structures, language processing, and acquisition. Papers report corpus data, neurological investigations, child language studies, and fieldwork from minority languages.

In this groundbreaking book, Tomasello presents a comprehensive usage-based theory of language acquisition. Drawing together a vast body of empirical research in cognitive science, linguistics, and developmental psychology, Tomasello demonstrates that we don't need a self-contained "language instinct" to explain how children learn language. Their linguistic ability is interwoven with other cognitive abilities.

This volume further elaborates the empirical tradition of Columbia School (CS) Linguistics by offering diverse empirical analyses for a wide variety of languages. These studies open a much needed debate advocating the necessity of the independent validation of linguistic hypotheses. This research exemplifies how such a validation should be conducted by determining which forms underlie the analyses and extracting those observations that are considered to be objective. The volume consists of two parts: a section on synchronic and diachronic grammatical problems and a section on Phonology as Human Behavior (PHB), the Columbia School version of phonology, applied to evolutionary, developmental and clinical issues and the phonotactics of the selected lexicon of a literary text. It provides a wealth of useful empirical data and in-depth and sophisticated qualitative and quantitative analyses of a broad range of languages from diverse families: French, Spanish, Afrikaans, Dutch, English, Polish, Russian, Japanese, and Hebrew.

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.
