Police interviewers should develop the ability to understand and interpret nonverbal communication because people react differently when giving truthful answers than when lying.
Abstract
Body movements can be revealing. Truthful persons tend to gesture away from their body, while liars tend to gesture toward themselves. In addition, a calm, emotionless face coupled with active arms, hands, legs, and feet may indicate deception; arms folded firmly and high across the chest may signify refusal or defiance. The personal distance between the interviewer and the person being interviewed can also affect the cooperation with the questioning. Other features that should be observed are facial expressions, physiological symptoms such as perspiration, and the speed and other aspects of the speech. To monitor and interpret nonverbal communication successfully, the interviewer should begin with small talk to build rapport and provide an opportunity to observe the person's truthful body language. The interviewer should next concentrate on gestures, facial expressions, and posture. They should also have an idea of the person's frame of reference and should always reserve judgment until after the interview. 7 reference notes
