闪回是创伤后应激障碍（PTSD）患者经历的无意识的、充满情感的图像。倒叙的性质在某些情况下可能导致源记忆错误。患有创伤后应激障碍的参与者撰写了创伤叙述并报告了闪回的经历。之后，他们会看到来自他们叙述中闪回和非闪回部分的刺激，以及来自另一名参与者叙述的陪衬，并判断它们是否属于他们自己的叙述。他们还报告了在这个识别测试中刺激是否引起闪回。总体而言，在测试中报告闪回与显着更好的识别性能相关。闪回偶尔被报告为衬托刺激，然后很可能被错误地归因于人自己的叙述。这为认知机制的概念提供了证据，这种认知机制可能会解释某些错误创伤记忆的情况。(C)2012爱思唯尔有限公司版权所有。
Flashbacks are involuntary, emotion-laden images experienced by individuals with posttraumatic stress disorder (PTSD). The qualities of flashbacks could under certain circumstances lead to source memory errors. Participants with PTSD wrote a trauma narrative and reported the experience of flashbacks. They were later presented with stimuli from flashback and non-flashback parts of their narrative, mixed with foils from the narrative of another participant, and judged whether they belonged to their own narrative. They also reported whether stimuli elicited a flashback during this recognition test. Overall reporting a flashback at test was associated with significantly better recognition performance. Flashbacks were occasionally reported to foil stimuli, which were then likely to be wrongly attributed to the person's own narrative. This provides proof of concept of a cognitive mechanism that could potentially account for some cases of false trauma memories. (C) 2012 Elsevier B.V. All rights reserved.
