'In reflecting on this book, I realised that I know of no comparable attempt to describe such a comprehensive, unified theory of cognition and emotion. It is particularly impressive in the way it combines a vision for what phenomena need to be explained with an attention to the specific detail of the mechanisms needed to explain them. Overall, it is characterised by a sympathy for the reader for whom many of the concepts may be unfamiliar.' - J. Mark G. Williams (University of Bangor) in Cognition & Emotion, 1994'This book represents a most impressive achievement. It is clearly the most sophisticated cognitive account of depression available, and the first to be integrated with a general model of cognitive functioning.' - Chris Brewin, Royal Holloway University of London'This thought provoking text describes a cognitive model which attempts to encompass all aspects of information processing in depression. This is a feat that current explanations have been unable to achieve.' - Lynn B. Myers in The Quarterly Journal of Experimental Psychology
