Traditional Techniques for Detecting Deception

Traditional techniques for detecting deception, such as the lie-detector test (or polygraph), are based upon the idea that lying is associated with stress. However, it is possible that people telling the truth will experience stress, whereas not all liars will. Because of this, the validity of such methods is questionable.

An Alternative Approach

As an alternative, a knowledge-based approach known as the Concealed Information Test has been developed which investigates whether the examinee recognizes secret information — for example, a crime suspect recognizing critical crime details that only the culprit could know. The Concealed Information Test has been supported by decades of research, and is used widely in Japan.

Target Audience

This is the first book to focus on this exciting approach and will be of interest to law enforcement agencies and academics and professionals in psychology, criminology, policing and law.
