Is Three Really a Crowd?: The Effects of Multiple Perpetrators on Eyewitness Identification Accuracy and Confidence

Abstract | Word Stems | Keywords | Association | Citation | Similar Titles



Abstract:

The purpose of this study was to examine the effects of multiple perpetrators on eyewitness identification accuracy. We examined the influence of number of perpetrators (1 vs. 2 vs. 3) as well as differences between simultaneous and sequential lineup procedures used in multiple perpetrator identifications. Results indicate that although almost half the participants made at least one correct lineup decision regardless of number of perpetrators shown, overall accuracy rates across all lineups were low in each perpetrator condition. In addition, a negative correlation was found between number of perpetrators and overall confidence ratings.
