Following exposure to a trauma, people tend to experience intrusive thoughts and memories about the event. In order to investigate whether intrusive memories in the aftermath of trauma might be accounted for by an impaired ability to intentionally forget disturbing material, the present study used a modified Directed Forgetting task to examine intentional forgetting and intrusive recall of words in sexual assault victims and controls. By including words related to the trauma in addition to neutral, positive, and threat-related stimuli it was possible to test for trauma-specific effects. No difference between the Trauma and the Control group was found for correct recall of to-be-forgotten (F) words or to-be-remembered (R) words. However, when recalling words from R-list, the Trauma group mistakenly recalled significantly more trauma-specific words from F-list. "Intrusive" recall of F-trauma words when asked to recall R-words was related to symptoms of post-traumatic stress disorder reported on the Impact of Event Scale and the Post-traumatic Diagnostic Scale. The results are discussed in term of a source-monitoring account.
创伤后，人们往往会经历关于该事件的侵入性思维和记忆。为了研究创伤后侵入性记忆是否可以归因于有意遗忘令人不安材料的能力受损，本研究使用改良的定向遗忘任务来检查性侵犯受害者和对照组的有意遗忘和侵入性回忆单词。通过在中性、积极和威胁相关刺激之外加入与创伤相关的单词，就有可能测试出创伤特异性效应。在遗忘（F）单词或记住（R）单词的正确回忆方面，创伤组和对照组之间没有发现差异。然而，当从 R 列表中回忆单词时，创伤组从 F 列表中错误地回忆出了明显更多的创伤特异性单词。当被要求回忆 R 列表中的单词时，对 F-创伤单词的“侵入性”回忆与事件影响量表和创伤后诊断量表上报告的创伤后应激障碍症状有关。结果根据来源监测账户进行了讨论。
