Beyond the Face: Nonverbal Messages from the Voice, Head, Eyes and Posture

This chapter discusses how nonverbal behaviors signal credibility, relational messages such as trust and affection or liking, and deception. The face is the most widely studied channel for credibility, trust, and deception but other useful codes including the voice, head movements, hand gestures, eye movements, and others are introduced. Using three illustrative investigations including group conversations while playing a game, a mock hiring task, and asynchronous job interviews, we demonstrate the utility of a wide variety of cues for assessments of credibility, composure, affection, and trustworthiness. The chapter summarizes the results of the three studies and provides insights into other applications including interview training, business negotiations, and interdisciplinary collaboration.
