This book introduces a developmental psychopathology approach to exploring the concept of autism in terms of three broad domains of development— physical, cognitive, and psychosocial—that are inextricably linked. Developmental psychopathology focuses on the interplay between normal and abnormal development. The juxtaposition of typical and atypical developmental patterns can better inform clinicians and parents of possible signs of achievement milestones that are missing or falling behind. This book consists of twelve chapters grouped under four parts, with each chapter's core content based on the most recent research findings and ending with the author's reflections on various parts of the chapter and a summary of the main points discussed. A final chapter addresses topics of utmost importance rarely discussed in books on autism. Appropriate for a wide range of professionals who work with clients who have autism, this book is a unique resource with approaches often overlooked in most books on autism.
