A collection of papers that explore bilingual children coping with two language systems.

This collection of original studies examines the cognitive processes and the fundamental mechanisms underlying adult second language acquisition.

Second Language Acquisition and the Critical Period Hypothesis is the only book on the market to provide a diverse collection of perspectives, from experienced researchers, on the role of the Critical Period Hypothesis in second language acquisition. It is widely believed that age effects in both first and second language acquisition are developmental in nature, with native levels of attainment in both to be though possible only if learning began before the closure of a "window of opportunity" – a critical or sensitive period. These seven chapters explore this idea at length, with each contribution acting as an authoritative look at various domains of inquiry in second language acquisition, including syntax, morphology, phonetics/phonology, Universal Grammar, and neurofunctional factors. By presenting readers with an evenly-balanced take on the topic with viewpoints both for and against the Critical Period Hypothesis, this book is the ideal guide to understanding this critical body of research in SLA, for students and researchers in Applied Linguistics and Second Language Acquisition.

Arturo Hernandez presents the results of 25 years of research into the factors that might help us to understand how two (or more) languages are stored in one brain. It is clear that the brain is not egalitarian—some languages are privileged and others are not, but why?

The initial state of learner spontaneous input processing in foreign language learning, as well as the extent to which this processing leads to intake, is of central importance to theoreticians and teachers alike. In this collection of original studies, leading experts examine a range of issues, such as what learners do when faced with a language they know little or nothing about, what factors appear to mediate beginning learners' processing of input, how beginners treat two types of information - form and meaning - in the input, and how adult cognition deals with stimulus frequency at this initial stage. This book provides a microscopic view on learners' processing of foreign language input at the early stages of learning, and evaluates a variety of methodological options within the context of ab initio processing of foreign languages other than English, such as German, Korean, Norwegian, Polish, and Spanish.

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.
