Dynamic Variation in Second Language Acquisition makes a cutting-edge contribution to knowledge about how second language learners develop their second language. Drawing comprehensively on Processability Theory’s theoretical understanding that individual variation dynamically interacts with ordered stages of language acquisition, the book provides an informative, critical analysis of historical and contemporary debates about the role of variation in linguistic variation, particularly second language variation. Richly illustrated with a forensic year-long study of how eight adolescent learners of English vary in their acquisition of syntax and morphology, this monograph shows that learners vary in their timing of development between two distinct learner types along a continuum and without skipping stages. The book uncovers how learner variation is dynamic and quite (although not entirely) systematic and how this variation contributes to change in the second language. It will be essential reading for researchers, students, and practitioners.

Recent work in applied linguistics has expanded our understanding of the rule governed nature of language. The concept of an idealized speaker -hearer whose linguistic competence is abstract and separate from reality has been enriched by the notion of an actual interlocutor who possesses communicative compe tence, a knowledge of language which accounts for its use in real-world con texts. Areas of variation previously relegated to idiosyncratic differences in performance have been found to be dynamic yet consistent and lend themselves to study and systematic description. Because language acquisition involves the development of communicative competence, by its very nature it incorporates variation and systematicity. Sec ond-language acquisition is similarly variable, since interlanguage is subject to the same universal and language-specific conventions. In addition, aspects of the second language have been found to be unevenly acquired and are differ entially reflected in particular contexts or settings. Yet, despite our expanding knowledge, this variability is only beginning to be treated in much of the sec ond-language acquisition literature. This volume presents the work of some researchers and methodologists who have taken on the challenge of including variation in their research designs and pedagogical recommendations. Variation is shown to be relevant to lin guistic, social, and psychological aspects of language. It is apparent in the registers and dialects of the target language and in the inter language of learners.

Dynamic systems theory, a general theory of change and development, offers a new way to study first and second language development and requires a new set of tools for analysis of empirical data. After a brief introduction to the theory, this book, co-authored by several leading scholars in the field, concentrates on tools and techniques recently developed to analyze language data from a dynamic perspective. The chapters deal with the general thoughts and reasoning behind coding data, analyzing variability, discovering interacting variables and modeling. The accompanying How to sections give step-by-step instructions to using macros to speed up the coding, creating a dedicated lexical profile, making min-max graphs, testing for significance in single case studies by running simulations, and modeling. Example files and data sets are available on the accompanying website (http://dx.doi.org/10.1075/lllt.29.website). Although the focus is on second language development, the tools are applicable to a wide range of phenomena in applied linguistics.

This volume corrects the relative neglect in Second Language Acquisition studies of the quantitative study of language variation and provides insights into such issues as language transfer, acquisition through exposure, language universals, learner's age and so forth. These studies bolster the idea that a full account of SLA development (and, hence, a “theory of SLA”) must be built on not only detailed accounts of interlanguage data but also on a wide appeal to factors which govern the psycholinguistic bases of SLA. An important addition to the volume is a comprehensive guide to both the DOS and Macintosh versions of the VARBRUL statistical program used by variationists.

Sociolinguistics and Second Language Acquisition is a comprehensive textbook that bridges the gap between the fields of sociolinguistics and second language acquisition, exploring the variety of ways in which social context influences the acquisition of a second language. It reviews basic principles of sociolinguistics, provides a unified account of the multiple theoretical approaches to social factors in second languages, summarizes the growing body of empirical research, including examples of findings from a wide range of second languages, and discusses the application of sociolinguistics to the second language classroom. Written for an audience that extends beyond specialists in the field, complete with summary tables, additional readings, discussion questions, and application activities throughout, this volume will serve as the ideal textbook for advanced undergraduate or graduate students of second language acquisition and instruction, and will also be of interest to researchers in the fields of second language acquisition, second language instruction and sociolinguistics.

Second language acquisition (SLA) is a field of inquiry that has increased in importance since the 1960s. Currently, researchers adopt multiple perspectives in the analysis of learner language, all of them providing different but complementary answers to the understanding of oral and written data produced by young and older learners in different settings. The main goal of this volume is to provide the reader with updated reviews of the major contemporary approaches to SLA, the research carried out within them and, wherever appropriate, the implications and/or applications for theory, research and pedagogy that might derive from the available empirical evidence. The book is intended for SLA researchers as well as for graduate (MA, Ph.D.) students in SLA research, applied linguistics and linguistics, as the different chapters will be a guide in their research within the approaches presented. The volume will also be of interest to professionals from other fields interested in the SLA process and the different explanations that have been put forward to account for it.
