Research on second language acquisition (SLA) has identified language aptitude and age of onset (AO), i.e., the age at which learners are first meaningfully exposed to the L2, as robust predictors of rate of classroom language learning and level of ultimate L2 attainment in naturalistic settings, respectively. It is not surprising, therefore, that recent years have witnessed a surge of interest in the combination of age and aptitude as a powerful explanatory factor in SLA, and central to a viable SLA theory. The chapters in this volume provide new studies and reviews of research findings on...

Cognitive Individual Differences in Second Language Processing and Acquisition contains 14 chapters that focus on the role of cognitive IDs in L2 learning and processing. The book brings together theoretical and methodological approaches to the study of cognitive IDs, as well as empirical studies that investigate the mediating role of cognitive IDs in various linguistic domains. Chapters include contributions from researchers working within second language acquisition (SLA), psycholinguistics, and cognitive psychology, sharing a common interest in the application of cognitive IDs to their...
