HANDS UP - A STUDY OF WITNESSES EMOTIONAL-REACTIONS AND MEMORIES ASSOCIATED WITH BANK ROBBERIES

This article presents some empirical findings concerning memory for violent real-life events. Witnesses who had observed a bank robbery, either as a victim or a bystander, were interviewed and studied with respect to emotional reactions and memory for detailed information about the robbery. The consistency of the witnesses' accounts was measured by a comparison of information gathered in the police reports and the recollection given in a research interview. Overall, the results showed relatively high accuracy rates after an extended time interval with respect to specific details about the robbery (e.g. action, weapon, clothing). For some details, however, the witnesses showed a rather low performance (e.g. colour of eyes and hair, and details of the surrounding circumstances). There was no significant relationship between rated degree of emotion and the number of details remembered. These findings contradict the negative relationship between stress and memory that many experts on eyewitness testimony believe in (Kassin, Ellsworth, and Smith, 1989). Points of commonality in findings from real-life studies and simulation studies are discussed.
