"Leonard's study will be indispensable for anyone who needs to keep current on child language development in general, and developmental language pathologies in particular... One of the preeminent scholars in the field, Leonard offers a fairly balanced view of specific language impairment in children, no easy task given the controversial nature of the subject. He also provides a comprehensive review of the literature, from the earliest beginnings of work in this field in the last century down to the very latest references. As a resource for students at all levels and for scholars of language development, this work is simply unparalleled." L. E. Hewitt, Choice "This book is a tour de force. I would expect the book to quicklybecome a classic reference in the field. It is extremely up-to-date,helped in part by the fact that Dr. Leonard is the author of some ofthe best research on the topic." Erika Hoff-Ginsberg , Professor of Psychology, Florida Atlantic University
Approximately five per cent of all children are born with the syndrome known as specific language impairment (SLI). These children show a significant deficit in spoken language ability with no obvious accompanying condition such as mental retardation, neurological damage, or hearing impairment. The book covers all aspects of SLI, including its history, possible genetic and neurobiological origins, and clinical and educational practice. It highlights important research strategies in the quest to find the cause of SLI and to develop methods of prevention and treatment. It also explores how knowledge of SLI may add to our understanding of language organization and development in general. Leonard does not limit his study to English, but shows how SLI is manifested in speakers of other languages. Although his focus is on children, he also discusses adults who exhibited SLI as children, as well as parents of children with the disorder whose own language abilities became the object of study.
