This book brings together a team of experts in the field of forensic psychology to demonstrate the scope of the discipline and the techniques employed in key areas of research, policy and practice. Its aim is to go beyond the introductory texts on the subject to challenge perceptions, to raise questions for research, to pose problems for practice, and to inspire and stimulate, demonstrating the ways in which forensic psychology can aid the practice of criminal justice. It will be essential reading for students, academics and practitioners. The book is divided into seven sections, addressing key topics with which the discipline is concerned - its broader context, investigation and prosecution, testimony and evidence, correlates of criminality, persistent offending, intervention and prevention and punishment and corrections. The contributors include both academics and practitioners, and are drawn from the UK, the USA and Australasia.
