A showup identification is the presentation of a single suspect to an eyewitness. I used a simulated theft paradigm and subsequent showup identification to examine the effects of stolen property, suspects??? verbal behaviour, and target-presence on eyewitness identification performance. I used a 2 (suspect: innocent, guilty) X 2 (stolen property: present, hidden) X 3 (verbal behaviour: denial with explanation, denial, silence) between-subjects factorial design. Binary logistic regression analysis indicated that both the target and stolen property, independently, and significantly predicted the accuracy of identification decisions. Surprisingly, the presence of stolen property facilitated more accurate identification decisions from eyewitnesses.
