This study tested the hypothesis that trauma memories are disjointed from other autobiographical material in posttraumatic stress disorder (PTSD). Assault survivors with (n = 25) and without PTSD (n = 49) completed an autobiographical memory retrieval task during script-driven imagery of (a) the assault and (b) an unrelated negative event. When listening to a taped imagery script of the worst moment of their assault, survivors with PTSD took longer to retrieve unrelated non-traumatic autobiographical information than those without PTSD, but not when listening to a taped script of the worst moment of another negative life event. The groups also did not differ in general retrieval latencies, neither at baseline nor after the imagery tasks. The findings are in line with suggestions that traumatic memories are less integrated with other autobiographical information in trauma survivors with PTSD than in those without PTSD.
这项研究检验了这样一个假设，即在创伤后应激障碍（PTSD）中，创伤记忆与其他自传体材料是不相关的。在对（a）攻击和（b）不相关的负面事件进行脚本驱动的意象时，患有 PTSD 的（n = 25）和没有 PTSD 的（n = 49）攻击幸存者完成了自传体记忆检索任务。当听他们攻击的最糟糕时刻的录音意象脚本时，患有 PTSD 的幸存者比没有 PTSD 的幸存者检索不相关的非创伤性自传体信息的时间更长，但在听另一个负面生活事件的最糟糕时刻的录音脚本时则不然。在基线和意象任务之后，两组在一般检索潜伏期方面也没有差异。这些发现与以下观点一致，即在 PTSD 创伤幸存者中，创伤记忆与其他自传体信息的整合程度低于没有 PTSD 的创伤幸存者。
