Eyewitness Identification And Eyewitness Fingerprints

Decent Essays

Eyewitness testimonies provide crucial evidence in pinpointing the identity of the perpetrator in order to solve a crime, thus the criminal justice system depends upon the accuracy of eyewitness identification to investigate and prosecute criminals. However, eyewitness identification is imperfect and the leading cause of wrongful convictions (Huff, Rattner, & Sagarin, 1996; Scheck, Neufeld, & Dwyer, 2000). One prominent method of eyewitness identification is a line-up procedure during which “A line-up is a procedure in which a criminal suspect (or a picture of the suspect) is placed among other people (or pictures of other people) and shown to an eyewitness to see if the witness will identify the suspect as the culprit in question” (Wells …show more content…

Lindsay and Wells (1985) devised an alternative line-up presentation procedure to reduce the tendency of eyewitnesses to rely on relative judgment. A Sequential Line-Up (SEQ) presents the eyewitness with only one suspect at a time and they respond to each suspect with either a positive identification or none (Wells & Olson, 2003). It was proposed that reasoned that this procedure may raise participants’ response criterion and evoke a more "absolute" criterion (i.e., Is this the perpetrator or not?) rather than the similarity based relative-judgment criterion, thereby alleviating the simultaneous bias (Ebbesen & Flowe, 2002; Lindsay & Wells, 1985). To compare the SEQ and SIM line-ups Lindsay and Wells (1985) used two conditions; a target-absent line-up, in which one an innocent suspect is embedded among fillers, and a target-present line-up in which the guilty suspect is embedded among fillers. This data found that the SIM and SEQ procedures produced nearly identical correct identification rates in the target-present trial whereas in the target-absent condition the rate of mistaken identifications the rate was 43% with the SIM procedure and only 17% with the SEQ method (Lindsay et al., 1991). Compared to SIM presentation, SEQ line-up presentation did not significantly influence the correct identification rate but
