Abstract (Summary)

Nonverbal cues are one of the most important sources of information in social interaction. One important source of nonverbal clues are facial expressions. Although research has examined overt facial expressions of emotion, very little research has examined the effect spontaneously generated microexpressions of emotion, which are facial expressions of emotion that last less than 500 ms. The present study sought to examine the role spontaneous microexpressions have on a human’s ability to detect deception, recognize emotions, perceive others on various traits, and how verbal information helps guide these perceptions. A mixed model design was employed where 84 participants were randomly assigned to an audio on or audio off condition. Participants viewed 16 videoclips of people spontaneously responding to a bitter or sweet drink, where they either lied or told the truth about their feelings. Participants viewed these responses and answered several questions about the reactions they witnessed. Results found participants were above chance recognizing both deception and emotion, and most accurate detecting lies that had microexpressions. Women were more accurate at recognizing the particular emotions expressed in the microexpression compared with men. Stimuli displaying microexpressions were perceived as less trustworthy, confident, honest, and more anxious than those displaying neutral expressions. The present study hopes to add further light and significance of spontaneous microexpressions in the recognition of deception, emotion, and trait perceptions.
