Each chapter examines the claims and scope of each theory and howeach views language, the learner and the acquisition process, supplemented by summaries of key studies and data examples from a variety of languages. Chapters end with an evaluative summary of the theories discussed. Key features to this fourth edition include updated accounts of developments in cognitive approaches to second language (L2) learning, the implications of advances in generative linguistics and the "social turn" in L2 research, with re-worked chapters on functional, sociocultural and sociolinguistic perspectives, and an entirely new chapter on theory integration, in addition to updated examples using new studies.
