According to Loftus and Burns (I 982), retrograde amnesia can result from witnessing a traumatic event. In this experiment, two groups of participants were surveyed after a brief presentation. One group witnessed a mildly traumatic event in the presentation and one did not. Both groups were then asked to recall information from the presentation. Compared with the non-trauma group, significantly fewer participants in the trauma group recalled information from the presentation (66.6% vs. 21.8%; chi-square test significant at the 0.001 level), supporting our hypothesis that witnessing tl mildly traumatic event may result in retrograde amnestic symptoms.
