A comprehensive introductory textbook...This book deserves the special attention of anyone who is interested in adult SLA. -- Language and Education, 2006

Unparalleled in its class - skillfully planned, cleverly organized and exceptionally well written. -- International Journal of Bilingual Education and Bilingualism

Equally valuable as a handbook or as a course text, this volume should be owned by any serious student or researcher in second language acquisition.

This text is a broad-ranging treatment of SLA, drawing out the research methodological, psycholinguistic, social-interactive, and pedagogical ramifications of a principled cognitive view of the field. The strengths and rigorous approaches of the Georgetown faculty and students' research in this area are revealed, while an informatively current and diverse set of topics and theories are addressed and analyzed. A valuable addition to the library of both the new student and experienced professionals.
