The mitigating effects of suspicion on post-identification feedback using a target present lineup.

摘要

This experiment used a target present photo-lineup and examined whether making participants suspicious of the motivations of a lineup administrator who gave post-identification feedback would reduce the confidence inflation found in previous studies using target absent lineups. The results showed that participants were not initially affected by the feedback or suspicion compared to the no feedback control. However, after a one week retention interval the effects of feedback returned, and the suspicion manipulation was able to mitigate those effects. This study offered support for the internal cues to accuracy hypothesis. The implications for the research are discussed.
