One of the most fascinating sub-divisions within the rapidly growing field of psychology and law is the area of deception detection. Traditionally this area has been characterised by a number of approaches which have analysed different aspects of deception such as verbal content, non-verbal behaviour, and polygraph testing. The last few years' intensive research has resulted in an impressive corpus of new knowledge about issues such as cross-cultural deception, the detection of simulated amnesia and false confessions, lie-catching expertise and how best to train professionals in detecting deception. This book provides a state-of-the-art account of current research and practice, written by an international team of experts and will be a valuable resource for academics, students, practitioners and all professionals within the legal domain who need to tackle questions of credibility and reliability.
