Wendy Lawson presents in simple terms her fundamental theory on Single Attention and Associated Cognition in Autism (SAACA), an approach that explains autism through the unique learning process of individuals on the autism spectrum. She explains that while neurotypical people can easily shift their attention from one interest to another, those on the autism spectrum tend to focus on one topic at a time, leading to deep and intense attention. Wendy describes practical outcomes for individuals, families, educators, and employers. She shows that when this unique learning process is understood, assessed, and adapted, individuals on the autism spectrum can be empowered to achieve their fullest potential. It is essential reading for anyone with a personal or professional interest in autism, including individuals on the spectrum and their families, educators, clinical practitioners, researchers, occupational therapists, and other professionals.
