Amazon customer review © As a professional counselor who recently started a support group for parents with autistic children this book has given me vital information on how to conceptualize this disorder. This knowledge has enabled me to connect with parents in a very realistic manner. When I interact with them and answer their questions, they hear the ring of truth in what I communicate to them about their child's behaviors and reality. I am very grateful to Uta Frith for writing such a fine book.

Amazon customer review © This is a book for researchers primarily. It introduces Frith's theory of weak central coherence as an underlying mechanism in autism. The theory runs (in a nutshell) that autistic individuals do not exhibit context appropriate responses to situation, events, etc. Relevance theory (cf. Sperber & Wilson) oils the wheels of Frith's theory.
The book opens with a long exegesis on a historical case and performs more than a bit of post mortem diagnosis. Such rational reconstructions of the past can be either very rivetting or tiresome. I wasn't convinced that the story avoided the latter pitfall. More enjoyable if shortened.
The rest of the book concentrates on theories of autism and their testability. The tussle between theory of mind (cf. Baron-Cohen's book: Mindblindness) is discussed and gives a brief foretaste of disputes that dominated the nineties'. However, the difficulty that central coherence itself faces is how to shape it into a coherent scientific theory? Frith doesn't entirely skirt this issue and there is much to be gained from simply reflecting on her approach to theory development.
Be warned that lighting up the research stage is a major focus of the work, and this will limit it's appeal. My final comment is not to buy this edition of the book, but to wait for the June 2003 edition. It can only be better.
