'Theoretically motivated research into aptitude for second language acquisition (SLA) under different conditions of exposure, and at different stages of development and levels of proficiency, is essential for aptitude test development, and for matching learners to optimal conditions of instruction. This book provides the most thorough, up-to-date summaries of these important cognitive, developmental, and educational issues available and is essential reading for all language educators and SLA researchers! Most highly recommended!' Peter Robinson, Professor of Second Language Acquisition, Aoyama Gakuin University
