This study investigated the effects of high and low levels of dissociation on information processing for analogue trauma and neutral stimuli. Fifty-four undergraduate females who reported high and low levels of trait dissociation were presented with two films, one depicting traumatic events, the other containing neutral material. Participants completed a divided attention task (yielding a proxy measure of attention), as well as explicit memory (free-recall) and implicit memory (word-stem completion) tasks for both films. Results indicated that the high DES group showed less attention and had poorer recall for the analogue trauma stimuli, relative to the neutral stimuli and the low DES group. These findings suggest that high levels of trait dissociation are associated with reductions in attention and memory for analogue trauma stimuli, relative to neutral stimuli and relative to low trait dissociation. Implications for the role of cognitive factors in the etiology of negative post-trauma responses are discussed.
本研究调查了高、低分离水平对模拟创伤和中性刺激信息处理的影响。54 名报告高、低特质分离水平的女大学生观看了两部电影，一部描绘创伤性事件，另一部包含中性材料。参与者完成了一项分散注意力任务（提供注意力的代理测量），以及对两部电影的外显记忆（自由回忆）和内隐记忆（词干补全）任务。结果表明，高 DES 组对模拟创伤刺激的注意力和回忆都比中性刺激和低 DES 组差。这些发现表明，与中性刺激和低特质分离相比，特质分离水平较高与对模拟创伤刺激的注意力和记忆减少有关。讨论了认知因素在消极创伤后反应病因中的作用。
