Appearing To Deceive while Answering Questions: Suspicion Bias, Probing Effects, and the Nonverbal Primacy Effect in the Courtroom.
Sakaguchi, Jo Ann; And Others
A study examined truth bias, probing, and prebriefing as they relate to perception of deception, and whether nonverbal cues can be stronger predictors of the perception of deception than verbal cues. Subjects, 113 students from a large western university, responded in their classrooms to 1 of 8 inductions formed to complete a 2 (probe, no probe) x 2 (prebrief, no prebrief) x2 (neighbor versus court-like setting) factorial design. Each induction introduced subjects to a dispute involving a student who had been accused of cheating on an in-class activity. In addition to deception ratings, subjects rated the impact of several verbal and nonverbal cues on their perceptions of the "defendant" in the scenario. A measure of truth bias (presumption/assignment of burden of proof) was developed and utilized. Results indicated that: (1) deception ratings were higher in the court-like setting than in the neighbor (interpersonal) setting; (2) the setting main effect was qualified within the setting by prebriefing interaction such that the prebriefing worked to reduce deception attributions in the neighbor setting versus the court-like setting; (3) probes were most likely to reduce perceptions of deceptiveness when a prebrief was not presented; and (4) in contrast to earlier studies, verbal cues were much stronger predictors of perception of deception than nonverbal cues.
