Abstract:

Deception commonly exists in personal communication, interrogation and security and people often attempt to detect it through nonverbal visual cues. The paradigms in deception research are categorized as forced, voluntary or mixed deception. During deception, people usually experience higher cognitive load, higher emotional arousal and more attempted control, which would lead to the changes in nonverbal visual cues, such as eye movements, facial expressions and gestures. Other influential factors such as inter-personal and intra-personal differences were also analyzed and discussed. Future studies should further investigate the psychological mechanisms of deception and the psychological implications of nonverbal visual cues. Researchers should conduct more field studies to better understand the relationship between deception and nonverbal visual cues, and employ state-of-the-art technology to precisely measure and analyze nonverbal behaviors during deception.

Key words: deception, nonverbal visual cues, ecological validity, accurate measurement
