Viewing composite sketches: lineups and showups compared

Authors


Abstract

This study assesses the effect of high-and low-similarity composites on identification accuracy, using both lineups and showups. Participants witnessed a mock crime scene, viewed a composite of the perpetrator, then attempted an identification. The results indicate that witnesses are not overly influenced by low-similarity composites on subsequent identification accuracy. There was also no evidence that showups were less accurate identification procedures than lineups, across composition conditions. In fact, in perpetrator absent situations, showups were better identification procedures than lineups in terms of accuracy. Copyright © 2006 John Wiley & Sons, Ltd.
