"This book provides a comprehensive description of the many facets of First Language, Bilingual, and Second Language Acquisition. Adams, Warren and Wright bring together a thoughtful and rigorous exploration of these three types of acquisitions and examine their similarities and differences. They draw on different theoretical positions and a large body of research literature which includes in depth descriptions of the various data collections that have been used. This is a book that will be extremely useful for those wishing to extend their understanding of how languages are acquired in different contexts."Rhonda Oliver, Curtin University, Australia"An engaging, research-forward introduction to language learning across contexts! Adams, Warren and Wright offer a research-based understanding of distinct but related types of language acquisition (first, bilingual and second). Readers gain insight into the overlaps and contrasts across these processes as well how this knowledge base draws from varied theoretical frameworks and fields."Kendall King, Professor of Multilingual Education, C&I, University of Minnesota, USA"This readable, informative and balanced introduction to first, second and bi-/multi-lingual language learning reflects the realities of the modern world, where acquiring only a single language is becoming vanishingly rare. As such it provides a solid foundation both for more advanced study and for application to modern teaching and therapy."Susan Foster-Cohen, Associate Professor, University of Canterbury, New Zealand
