This book will be of interest to a broad range of disciplines including psychology, child development, early childhood education, social work, pediatrics, nursing, child psychiatry, physical and occupational therapy, speech and language pathology, and social policy. A scholarly overview of the underlying knowledge base and practice of early childhood intervention, it is unique in its balance between breadth and depth and its integration of the multiple dimensions of the field.
