• This state-of-the-art text reviews, evaluates, and reflects on L2 development across the lifespan as a complex variable that is both socio-cultural as well as maturational in nature – with a chronological chapter lineup from infant bilinguals to L2 learners in adolescence, adulthood, and older age. • Offers in-depth discussion of highly pertinent yet underresearched topics, like L2 learners in older individuals, as well as an innovative chapter on L2 learning in the context of cross-cultural/binational/plurilingual romantic relationships, in both cases with diverse circumstances, motivations, and outcomes. • The first book taking on this area in its fullness and in a way accessible to students and non-specialist – with a concerted, authored text. Previous works are focused on one age cohort, edited volumes rather than unified authored books, and the most closely competing books were published over a decade (and sometimes over three decades) ago.

This volume offers several empirical, methodological, and theoretical approaches to the study of observable variation within individuals on various linguistic levels. With a focus on German varieties, the chapters provide answers on the following questions (inter alia): Which linguistic and extra-linguistic factors explain intra-individual variation? Is there observable intra-individual variation that cannot be explained by linguistic and extra-linguistic factors? Can group-level results be generalised to individual language usage and vice versa? Is intra-individual variation indicative of actual patterns of language change? How can intra-individual variation be examined in historical data? Consequently, the various theoretical, methodological and empirical approaches in this volume offer a better understanding of the meaning of intra-individual variation for patterns of language development, language variation and change. The inter- and transdisciplinary nature of the volume is an exciting new frontier, and the results of the studies in this book provide a wealth of new findings as well as challenges to some of the existing findings and assumptions regarding the nature of intra-individual variation.

This book constitutes a holistic study of how and why late starters surpass early starters in comparable instructional settings. Combining advanced quantitative methods with individual-level qualitative data, it examines the role of age of onset in the context of the Swiss multilingual educational system and focuses on performance at the beginning and end of secondary school, thereby offering a long-term view of the teenage experience of foreign language learning. The study scrutinised factors that seem to prevent young starters from profiting from their extended learning period and investigated the mechanisms that enable late beginners to catch up with early beginners relatively quickly. Taking account of contextual factors, individual socio-affective factors and instructional factors within a single longitudinal study, the book makes a convincing case that age of onset is not only of minimal relevance for many aspects of instructed language acquisition, but that in this context, for a number of reasons, a later onset can be beneficial.

This edited volume provides an overview of current thinking and directions for further research in applied linguistics by bringing together in a single volume a range of perspectives regarding original research agendas and innovative methodological approaches. It focuses not only on the challenges that applied linguistics researchers have been facing in recent years but also on producing workable and productive research designs and on identifying ways of how alternatives to conventional research methodologies can be used. Discussions featured in the volume include the so-called ‘Bilingual Advantage’ in psycho- and neurolinguistics; the optimal starting age debate in foreign language learning; the growing interest among applied linguists in more nuanced and more complex (statistical) data analysis and the priority given to more descriptive and social approaches to linguistics rather than to theorising. The collection will be a useful reference and stimulus for students, researchers and professionals working in the areas of applied linguistics, psycholinguistics, second language acquisition and second language education.

Bringing together experts from both historical linguistics and psychology, this volume addresses core factors in language change from the perspectives of both fields. It explores the potential (and limitations) of such an interdisciplinary approach, covering the following factors: frequency, salience, chunking, priming, analogy, ambiguity and acquisition. Easily accessible, the book features chapters by psycholinguists presenting cutting edge research on core factors and processes and develops a model of how this may be involved in language change. Each chapter is complemented with one or several case study in the history of the English language in which the psycholinguistic factor in question may be argued to have played a decisive role. Thus, for the first time, a single volume provides a platform for an integrated exchange between psycholinguistics and historical linguistics on the question of how language changes over time.
