In the extract the authors state that the aim of the experiment was to determine if the composite-building process could harm (or alter) the builder’s remembrance of a face in a lineup identification situation. The study also seems to have a number of secondary aims with the two experiments using still photos in the lineup in experiment #1 and the eyewitnesses watching a replicated crime video in its place of still photos for experiment #2. The 2nd experiment also questions what will happen if the witness views a lineup that does not contain the actual target, whereas in the first experiment the target was always in the lineup.

2: Indicate whether or not the study was theoretically motivated:
The introduction segment of the article delivers substantial review of the literature that has driven the study. They note that over the last 25-30 years, cognitive and social psychologists have performed research questioning the accuracy of eyewitness identification evidence and are planning methods to advance eyewitness identification precision (Cutler & Penrod, 1995; Wells, 1993). Additionally they note that the U.S justice system has now started to incorporate better methods of eyewitness identification based on this psychological research (Wells et al., 2000).
The authors’ state that over the last decade, “forensic DNA testing has been used to exonerate people who were convicted of crimes they did not commit, and the vast
