This authoritative handbook reviews the breadth of current knowledge about developmental disabilities: neuroscientific and genetic foundations; the impact on health, learning, and behavior; and effective educational and clinical practices. Leading authorities analyze what works in intervening with diverse children and families, from infancy through the school years and the transition to adulthood. Chapters present established and emerging approaches to promoting communication and language abilities, academic skills, positive social relationships, and vocational and independent living skills. Current practices in positive behavior support are discussed, as are strategies for supporting family adaptation and resilience. This book is divided into seven parts.
