Effects of stress induced by a simulated shooting on recall by police and citizen witnesses.
Two experiments address the accuracy of citizen and police witnesses in recalling stressful events. Participants saw 2 training scenarios. Experiment 1 evaluated the effects of active engagement and the presence of a simulated shooting on police officers' memory for details. Police officers recalled significantly fewer details from the scenario in which a shooting occurred. Active engagement did not influence recall. Experiment 2 compared the memory performance of police and citizen witnesses. Manipulation checks were added to assess the arousal produced by a shooting, and control procedures were added to evaluate the memorability of specific scenarios. Police and citizen witnesses did not differ reliably in accuracy. The perpetrator was remembered less well than the weapon when a simulated shooting occurred, and one scenario was significantly more difficult to remember than the other. The need to replicate eyewitness research with a variety of materials is discussed.
