Abstract
The post-identification feedback effect (PIFE) refers to the distortion of eyewitness memory after receiving feedback implying their identification was either correct or incorrect. Although previous studies indicate that feedback influences eyewitness memory, it is not clear if this distorted memory will alter eyewitness behavior. In this study, we explored whether people who received confirming feedback were more likely to provide experimental data as evidence for an ongoing trial. Immediately after making identification, participants were given either confirming feedback (Good, you identified the suspect), disconfirming feedback (Actually, the suspect was number_), or no feedback. After receiving this feedback, all participants answered dependent measures. Our results replicated the PIFE. However, participants who were given confirming feedback were not significantly more likely to provide experimental data than the other groups.
