Listening, not watching: Situational familiarity and the ability to detect deception

摘要

In 4 experiments, the authors investigated the influence of situational familiarity with the judgmental context on the process of lie detection. They predicted that high familiarity with a situation leads to a more pronounced use of content cues when making judgments of veracity. Therefore, they expected higher classification accuracy of truths and lies under high familiarity. Under low situational familiarity, they expected that people achieve lower accuracy rates because they use more nonverbal cues for their veracity judgments. In all 4 experiments, participants with high situational familiarity achieved higher accuracy rates in classifying both truthful and deceptive messages than participants with low situational familiarity. Moreover, mediational analyses demonstrated that higher classification accuracy in the high-familiarity condition was associated with more use of verbal content cues and less use of nonverbal cues.
