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 book examines the evidence relative to the idea that there is an age factor in first and second language acquisition, evidence that has sources ranging from studies of feral children to evaluations of language programmes in primary schools. It goes on to explore the various explanations that have been advanced to account for such evidence. Finally, it looks at the educational ramifications of the age question, with particular regard to formal second language teaching in the early school years and in ‘third age’ contexts.

The evidence for an age factor in language acquisition is examined here, from studies of "wolf children" to the mental capacities of the very old. The book also covers broader theoretical issues and, on a practical note, the ramifications of the age question with regard to second language tuition.

Informal language learning beyond the classroom plays an important and growing role in language learning and teaching. This Handbook brings together the existing body of research and unites the various disciplines that have explored this area, in order to present the current state of knowledge in one accessible resource. Much of adult learning takes place outside of formal education and for language learning, it is likely that out-of-class experiences play an equally important role. It is therefore surprising that the role of informal language learning has received little attention over the years, with the vast majority of research instead focusing on the classroom. Researchers from a range of backgrounds, however, have started to realise the important contribution of informal language learning, both in its own right, and in its relationship with classroom learning. Studies in the areas of learner autonomy, learning strategies, study abroad, language support, learners’ voices, computer-mediated communication, mobile-assisted language learning, digital gaming, and many others, all add to our understanding of the complex and intersecting ways in which learners construct their own language learning experiences, drawing from a wide range of resources, including materials, teachers, self-study, technology, other learners and native speakers. This Handbook provides a sound and comprehensive basis for researchers and graduate students to build upon in their own research of language learning and teaching beyond the classroom.

The Routledge Handbook of Second Language Acquisition and Individual Differences provides a thorough, in-depth discussion of the theory, research, and pedagogy pertaining to the role individual difference (ID) factors play in second language acquisition (SLA). It goes beyond the traditional repertoire and includes 32 chapters covering a full spectrum of topics on learners’ cognitive, conative, affective, and demographic/sociocultural variation. The volume examines IDs from two perspectives: one is how each ID variable is associated with learning behaviors, processes, and outcomes; the other is how each domain of SLA, such as vocabulary or reading, is affected by clusters of ID variables. The volume also includes a section on the common methods used in ID research, including data elicitation instruments such as surveys, interviews, and psychometric testing, as well as methods of data analysis such as structural equation modeling. The book is a must-read for any second language researcher or applied linguist interested in investigating the effects of IDs on language learning, and for any educator interested in taking account of learners’ individual differences to maximize the effects of second language instruction.

Language fundamentally defines and distinguishes us as humans, as members of society, and as individuals. As we go through life, our relationship with language and with learning shifts and changes, but it remains significant. This book is an up-to-date resource for graduate students and researchers in second language (L2) acquisition who are interested in language learning across the lifespan. The main goal is to survey and evaluate what is known about the linguistic-cognition-affect associations that occur in L2 learning from birth through senescence (passing through the stages of childhood, adolescence, adulthood, and third age), the extent to which L2 acquisition may be seen as contributing to healthy and active aging, the impact of the development of personalized, technology-enhanced communicative L2 environments, and how these phenomena are to be approached scientifically and methodologically. The effects of certain specific variables, such as gender, socio-economic background, and bilingualism are also analyzed, as we argue that chronological age does not determine the positioning of L2 learners across the lifespan: age is part of a complex web of social distinctions such as psychological and individual factors that intersect in the construction of a learner’s relative status and opportunities.

This book examines the assumptions that are customarily made about the role of age in second language acquisition. The evidence and arguments presented in the book run counter to the idea that an early start in second language learning is either absolutely sufficient or necessary for the attainment of native-like mastery of a second language.
