lineup is one of the two methods used for eyewitnesses to identify criminals in police station. In a standard sequential lineup, the suspects or their photos are presented one at a time to the witnesses only once. Witnesses make decisions about each individual suspect before the next one is shown and they do not know the total number of suspects. History Although it is hard to pinpoint exactly when sequential lineups were first studied, the knowledge that simultaneous lineups often failed and convicted an innocent person has been common knowledge for many years. The advance of the popularity of sequential lineups can be traced to the Innocence Project and Gary Wells. Wells has many studies that show that sequential lineups lead to fewer wrongful convictions. The early studies of sequential lineups found that there was a significant difference in the wrongful conviction of innocent persons. Since these early studies there has been a push to increase the accuracy of eyewitness memory even more. One way this is accomplished is by having not just sequential lineups, but also double-blind sequential lineups. A double-blind sequential lineup is conducted by making sure that neither the witness nor the person conducting the lineup has any idea who the suspect is. This eliminates any bias the person conducting the lineup may have. The research for double-blind studies has shown that "now we have proof from the field that witnesses who view double-blind sequential lineups are just as likely to pick the suspect, and perhaps more importantly, less likely to make a misidentification by picking a filler in the lineup." The study of sequential lineups is far from being finished and there is still much left to prove. The New York Times reported that Wells will continue to "examine the data gathered to gauge the level of certainty of witnesses and the effect of factors like cross-racial identification on accuracy." Sequential lineup laps A sequential lineup lap is showing the suspects repeatedly after the first round while in a standard sequential lineup eyewitnesses can only view them once. The thinking is that viewing the suspects again can increase the accuracy of identification since the eyewitnesses will be more certain about their answer. Research found that viewing the suspects once more has a large influence on witnesses' performance. Many witnesses moved from no-choice to choice, some changed answers and their confidence went up. Both correct identification rate
