There is an ongoing debate whether or not patients with post-traumatic stress disorder (PTSD) are more prone to produce false memories. The present study investigated this question using a visual variant of the Deese-Roediger-McDermott (DRM) paradigm, additionally addressing underlying mechanisms of false memory production (e.g., depression, dissociation, emotional valence, arousal). The visual paradigm was administered to 48 traumatized individuals with (n=20) and without PTSD (n=28) and 28 non-traumatized controls. Groups did not differ with regard to memory performance and memory confidence. False memories were correlated with depression. We recommend that future studies employ trauma-related material to further explore memory aberrations in PTSD.
创伤后应激障碍(PTSD)患者是否更容易产生错误记忆,目前仍存在争议。本研究使用Deese-Roediger-McDermott(DRM)范式的视觉变体对这一问题进行了调查,此外还探讨了错误记忆产生的潜在机制(如抑郁、解离、情绪效价、唤醒)。对48名受过创伤的个体(其中20名患有PTSD,28名未患PTSD)和28名未受过创伤的对照组进行了视觉范式测试。各组在记忆表现和记忆信心方面没有差异。错误记忆与抑郁相关。我们建议未来的研究采用与创伤相关的材料,以进一步探索PTSD中的记忆异常。
