'Wondering about the World' is an impressive, comprehensive, highly readable and much needed guide to autistic spectrum conditions. Autism is presented from a new biopsychological perspective which is supported by the latest research. Delfos' theory of the Socioscheme alongside the MAS1P, the broad 'Mental Age Spectrum within 1 Person', shows the effects of the rainbow of ages within each person with autism and demonstrates how they can be both older and younger than their chronological age and therefore uncovers their hidden intelligence. The theory of Delfos is widely embraced by people with autism conditions and their families and carers, and is gaining international recognition. Martine Delfos provides a strong, insightful and clear theoretical analysis of the nature of autism and the challenges it may cause. Special attention is given to differentiating trauma with autistic behaviour from autism spectrum conditions. Illustrating her ideas with many real-life examples, Delfos offers practical advice from the perspective of people with autism of all ages, as well as from parents and carers. While incorporating the most recent findings of current research her experience in practice means she is able to balance theory and practical advice to perfection. Wondering about the World is both an accessible resource for parents and an important textbook for students and professionals. Martine F. Delfos (PhD) is a biopsychologist working as a researcher and therapist for people with a broad spectrum of issues.

The author also has notable respect for those who have autism and Asperger's Syndrome and she is able to challenge and change attitudes as well as increase understanding."
