Beginning from the conflict between individual learner differences and the institutionalized, often inflexible character of formal language instruction, Individual Learner Differences in SLA addresses the fact that despite this apparent conflict, ultimate success in learning a language is widespread. Starting with theoretically-based chapters, the book follows the thread of learner differences through sections devoted to learner autonomy; differentiated application of learning strategies; diagnostic studies of experienced learners’ management of the learning process; and reports on phonological attainment and development of language skills. Rather than providing an overview of all individual variables, the book reveals how some of them shape and affect the processes of language acquisition and use in particular settings.
