Autism is a neurodevelopmental disorder that allows a unique window on the relationship between mind and brain. The study of autism provides insight into the brain basis of the complex social interactions typical of human beings, since a profound impairment in social interactions is the hallmark of autistic disorders. While autism was first described almost 60 years ago, research into its cognitive and neurophysiological basis has intensified over the last two decades. Autism: Mind and Brain provides a comprehensive overview of currently conducted experiments, which are guided by bold theories that are being tested rigorously. With contributions from international leaders in autism research, the book focuses on new ideas and findings that are gradually influencing our understanding of autism and its variants. These new approaches include the use of functional and structural brain imaging studies as well as novel behavioural measures. Together they demonstrate significant advances in knowledge and testify to the development and integration of current cognitive theories of autism. The application of these new and sophisticated approaches forge a path forward for future autism research, and present powerful new insights into this fascinating and still puzzling disorder.
