Nonverbal Cues

When you interview your subject, he or she will provide a variety of nonverbal cues during the responses. These cues provide additional important signs of deception and can be used to determine if your rapport-building efforts are working or failing. Nonverbal cues are physical movements of the body. People possess characteristic nonverbal ways of reacting while communicating. These reactions often represent an unconscious, emotional reaction to something they are thinking about or saying. As with verbal cues, look for departures from a person's typical nonverbal actions to detect deception. Compare the truth-telling style with the deceptive behavior.
