Completely revised and updated, this book focuses on sensory perceptual problems as identified by individuals on the autism spectrum. Despite frequently being identified by individuals with autism as one of the main problems they face, sensory perceptual issues are still often overlooked by professionals. The author covers the sensory perceptual experiences and sensitivities seen in autism spectrum conditions, and the cognitive differences caused by them. She considers assessment and intervention, and makes practical recommendations for selecting appropriate methods and techniques to eliminate sensory perceptual problems and enhance individual strengths. Brought up-to-date with current research and the latest thinking on autism, this book enables teachers, parents, professionals and individuals with autism fully to understand and address the problematic aspects of the sensory perceptual differences of people with autism spectrum conditions.
