Dr. Vance conducted an experiment to investigate the weapon focus effect on the accuracy of eyewitness identification. She showed a sample of 35 elderly residents from a local retirement community a short video clip of a convenience store robbery. In the video, the perpetrator held either a large silver handgun (weapon condition) or a bright blue water bottle (control condition). Afterward, she asked participants to select the perpetrator's face from a 6-person photographic lineup.
