Chapters written by leading authorities offer current perspectives on the origins and development of language disorders. They address the question: How can the child's linguistic environment be restructured so that children at risk can develop important adaptive skills in the domains of self-care, social interaction, and problem solving? This theory-based, but practical book emphasizes the importance of accurate definitions of subtypes for assessment and intervention. It will be of interest to students, researchers, and practitioners in the field of developmental language disorders.
