Chris Brewin is the Professor of Psychology at University College London and is an expert in both post-traumatic stress disorder (PTSD) and memory. This volume is from the Current Perspectives in Psychology Series.

As the title might lead one to expect, Professor Brewin initially explores the topic in an adversarial way, presenting the argument for and against the concept of PTSD and the relative aetiological importance of exposure to a traumatic event compared with premorbid vulnerability. This is well-travelled ground and those whose special interest is PTSD will not find anything particularly new or startling in the first third of the book. However, it is a good overview of the area and with an international rather than purely North American perspective. Less predictable, and arguably more interesting, Brewin then reviews the evidence and explores possible theories that explain the laying down of traumatic memories and how this process might shed light on the core symptoms of the disorder. This forms a substantial part of the book and it is not something that one could readily deduce from the title, which is a pity as there are few reviews of this subject in the PTSD literature.

The author covers a wide range of issues related to memory, including concepts of repression, the recovered memory debate and how this relates to Freudian theory. He criticises both sides of the debate for failing to distinguish between observations and theoretical explanation. He then presents some of his own research on memory inhibition and argues for the concepts of a visual accessible memory (VAM) and a situational accessible memory (SAM), which form part of the dual representation theory for PTSD. This provides a feasible explanation for the phenomena of repression and dissociation.

One chapter covers the prevention and treatment of PTSD, including the controversial area of psychological debriefing. Finally, there is a summing up and a look to the future.

Overall, this is a well-written volume with excellent and comprehensive references (although I would have preferred a title that was more indicative of the content). It would be of value both to a relative newcomer to the subject and to an expert.
