This study is an examination of two forensically important but previously neglected issues in interpersonal deception. First, which cues do lie catchers-who have access to repeated interrogations-pay attention to in order to detect deception? Second, do face-to-face interacting interrogators differ from noninteracting observers in terms of how they perceive a suspect? After watching a staged event, 24 suspects (12 liars and 12 truth tellers) were interrogated three times over a period of 11 days. After the final interrogation, the veracity of each suspect was assessed by his or her interrogator and by 6 observers who had watched the interrogations on video only. The results of the experiment showed that consistency over time was by far the most commonly used cue for justifying veracity judgments. Critically, the predictive accuracy for this cue was alarmingly low. As opposed to results from previous research, the interrogators used verbal cues to a significantly greater extent than did the observers. Furthermore, a probing effect was shown (i.e., probed suspects were perceived as significantly more honest than nonprobed suspects). Finally, limited support for a previously reported honesty effect was obtained (i.e., that interrogators perceive suspects to be more honest than do observers).
