The contribution of psychological research to the prevention of miscarriages of justice and the development of effective investigative techniques is now established to a point where law enforcement agencies in numerous countries either employ psychologists as part of their staff, or work in cooperation with academic institutions. The application of psychology to investigation is particularly effective when academics and practitioners work together. This book brings together leading experts to discuss the application of psychology to criminal investigation. This book offers an overview of models of investigation from a psychological and practical view point, covering topics such as investigative decision making, the presentation of evidence, witness testimony, the detection of deception, interviewing suspects and evidence-based police training. It is essential reading for students and researchers engaged with police practice, investigation and forensic psychology.
