The present study explored the effect of verbal dissembling on nonverbal behavior. Subjects were 146 females who were led to be either truthful or deceptive verbally to a confederate. The underlying affective state of the subjects and the publicness of the interaction between subject and confederate were also varied experimentally. The nonverbal behavior of the subjects was analyzed using objective scoring by trained coders and by showing samples of subjects' behavior to naive judges who rated how pleased the subjects appeared. Results showed that nonverbal behavior tended to reflect whether a subject was dissembling or being truthful. In addition, when they were truthful, subjects revealed their underlying affective states. However, when lying, there was no difference in nonverbal behavior according to the affect felt for the confederate. The nonverbal behavior of the subjects also tended to differ according to whether they were interacting publicly or privately; in public, subjects appeared more pleased with the confederate than in private.
