The language experience of children developing in linguistically diverse environments is subject to considerable variation both in terms of quantity and quality of language exposure. It is an open question how to investigate language exposure patterns and more important which factors are relevant for successful language learning. For example, children acquiring a minority language, including a signed language, are exposed to less variety of input than children acquiring a more global language. This is because they are living in a smaller linguistic community and with fewer occasions to use the language in everyday life. Despite this reduced input, most native signers are successful language learners. In contrast native language competence is not always achieved in signing deaf children with hearing parents or those with cochlear implants learning a spoken language. A similar outcome but with very different reasons has also been reported for hearing children with language impairment. In these populations acquisition of morphosyntactic aspects is developing atypically ending with an uncomplete linguistic repertoire. The circumstances of exposure during language development tend to differ in significant ways with respect to a large number of factors, such as, (i) length, quality and quantity of input, (ii) social status and attitudes toward the language, (iii) cognitive abilities required for language learning, and (iv) age of first exposure. Having early exposure to a range of different speakers is important in the acquisition of any language and may affect language proficiency. However, negative societal attitudes or a cognitive based disadvantage may create an unfavourable learning environment that prevents language learning from surfacing typically. This situation inevitably generates a different type of exposure for the child and consequently different language competence. In this Research Topic we intend to encourage the debate on social, linguistic and cognitive factors at play for designing an effective environment for language acquisition aiming at integrating linguistic variables coming from theoretical studies on language with environmental variables, such as, measures of language input or cognitive abilities on functions ancillary to language development.

In recent years the field has seen an increasing realisation that the full complexity of language acquisition demands theories that (a) explain how children integrate information from multiple sources in the environment, (b) build linguistic representations at a number of different levels, and (c) learn how to combine these representations in order to communicate effectively. These new findings have stimulated new theoretical perspectives that are more centered on explaining learning as a complex dynamic interaction between the child and her environment. This book is the first attempt to bring some of these new perspectives together in one place. It is a collection of essays written by a group of researchers who all take an approach centered on child-environment interaction, and all of whom have been influenced by the work of Elena Lieven, to whom this collection is dedicated.

A clear and practical introduction to second language acquisition, written for students encountering the topic for the first time.

This volume is a collection of nine original papers exploring dimensions of individual difference in language learning from narrative and biographical perspectives. This volume is a collection of nine original papers exploring dimensions of individual difference in language learning from narrative and biographical perspectives. Topics covered include motivation, emotion, age, learning strategies and beliefs, identity and the influence of classroom, distance and self-instructional settings. The authors use a variety of research methods to investigate learners' experiences of these aspects of the learning process. Among the countries represented in the research are Australia, Bahrain, China, Japan, Taiwan, Thailand, New Zealand, Peru, the United Kingdom and the United States. The studies will be of interest to teachers, teachers-in-preparation, teacher educators and researchers.

Introduction to Instructed Second Language Acquisition is the first book to present a cohesive view of the different theoretical and pedagogical perspectives that comprise instructed second language acquisition (ISLA), defined as any type of learning that occurs as a result of the manipulating the process and conditions of second language acquisition. The book begins by considering the effectiveness of ISLA and the differences between ISLA and naturalistic L2 learning. It then goes on to discuss the theoretical, empirical, and pedagogical aspects of such key issues in ISLA as grammar learning; interaction in the classroom; focus on form, function and meaning; vocabulary learning; pronunciation learning; pragmatics learning; learning contexts; and individual differences. This timely and important volume is ideally suited for the graduate level ISLA course, and provides valuable insights for any SLA scholar interested in the processes involved in second language learning in classroom settings.
