Summary

The central thesis of this book is both challenging and controversial:that the features of psychotic disorders such as schizophrenia actually lie on acontinuum with, and form part of, normal behaviour and experience. Thedispositional or "schizotypal" traits associated with psychotic disorderscertainly predispose an individual to mental illness, but they may also lead topositive outcomes such as enhanced creativity or spiritual experience.Discussion of each aspect of this theme is supported by extensive experimentaland clinical evidence, questioning the received medical wisdom which treatspsychotic illness in the narrow context of neurological disease. The result isan authoritative and provocative overview of an important topic in psychologicalresearch and clinical practice.
