Summary
"A major focus of eyewitness research is to improve police lineup procedures by increasing or maintaining the likelihood that the witness will make a correct identification while reducing the likelihood that an innocent person will be identified. This study (N =280) examined the potential of achieving these goals using a recently proposed lineup . procedure - the 40-person Multiple-choice, Sequential, Large (MSL) lineup (Levi, 1998, 2002). The results indicated that this procedure produced a lower rate of correct identifications overall compared to the simultaneous lineup. Furthermore, accuracy decreased as the guilty person was presented later in the 40-person lineup. However, the chance that any individual lineup member would be selected when innocent was lower with the MSL lineup than with traditional lineup procedures. The MSL procedure may be effective if restricted to 20 members; however, further research is recommended."--Abstract.
