ABSTRACT
This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. This book, The Cognitive Neuropsychology of Schizophrenia (CNS), aims to show how the various signs and symptoms associated with schizophrenia might be understood in terms of cognitive processes. The author's idea of self-monitoring, which involved a comparison between an intended action and the actual action, was replaced by a precise mechanistic account in terms of forward and inverse models. He uses the phrase cognitive neuropsychology in the title of my book to link it with approaches, current at that time, to explaining the psychological effects of brain lesions in terms of cognitive processes. Impairments in social cognition more generally, but especially impairments in Theory of Mind tasks, seem to be the best predictors of impaired functioning in the community, although only accounting for 25" of the variance.
