患有创伤后应激障碍（PTSD）的人经常报告在与他们的创伤无关的任务上的注意力和记忆力困难。日常事件理解的一个重要组成部分是将正在进行的活动分割为有意义的事件。本研究询问PTSD症状的严重程度是否与中性持续活动的分割和记忆受损相关。137名年龄在21-79岁之间的参与者完成了事件分割和记忆任务，一般认知功能任务和评估PTSD症状严重程度的问卷调查。PTSD症状水平较高的人的事件分割和事件记忆表现较差。分层多元回归分析表明，PTSD症状的严重程度解释了独特的事件分割性能的变化，即使在控制一般的认知功能。这些结果表明，旨在改善事件理解的干预措施可能有助于弥补创伤后应激障碍的记忆中断。
People with Posttraumatic Stress Disorder (PTSD) often report difficulties with attention and memory on tasks that are unrelated to their trauma. One important component of everyday event comprehension is the segmentation of ongoing activity into meaningful events. The present study asked whether PTSD symptom severity was associated with impaired segmentation and memory for neutral, ongoing activity. A sample of 137 participants, ages 21-79, completed event segmentation and memory tasks, general cognitive functioning tasks, and questionnaires assessing PTSD symptom severity. People with higher levels of PTSD symptoms had poorer event segmentation and event memory performance. Hierarchical multiple regression analyses demonstrated that PTSD symptom severity explained unique variance in event segmentation performance, even after controlling for general cognitive function. These results suggest that interventions aimed at improving event comprehension may help compensate for memory disruptions in PTSD.
