Deception, Verdicts, Nonverbal communication


Interpersonal communication is both verbal and nonverbal. These two channels function most often in a supplementary fashion to each other (Ekman & Friesen, 1969). For example, the message that emanates from a person's facial expression is typically consistent with that person's verbal message. However, these communication modes can sometimes be quite contradictory in the information they impart. In the present study, people's judgements when confronted with incongruent interchannel information were investigated. The focus was on observers' decisions regarding the believability of another's verbal message when delivered in conjunction with nonverbal behaviors characteristic of deception.
