由于工作记忆（WM）容量有限，有效抑制不再相关的记忆内容（抑制）和修正当前记忆内容（更新）是记忆的关键因素。然而，并不是每个人都能做到这一点；其中包括创伤后应激障碍（PTSD）患者，他们似乎很难忘记与创伤有关的材料，使他们的记忆中充斥着不相关的信息。本研究假设创伤后应激障碍患者无法遗忘是由于WM更新功能受损，因此表明这些个体对情绪和非情绪材料的WM功能都较差。30名患有PTSD的男性退伍军人和30名健康个体（平均年龄46.62岁，SD = 5.23岁）参加了研究，完成了PTSD检查表、数字跨度任务和计算机n-back任务。结果显示，虽然PTSD受试者的WM水平普遍低于正常人；然而，他们在情绪和非情绪刺激下的WM表现无显著差异。支持该研究的主要假设，研究结果表明，WM功能失调的更新功能是遗忘和记忆的基础，它同样影响对情感和非情感材料的记忆。
Due to the limited capacity of working memory (WM), efficient suppression of no longer relevant memory contents (inhibition) and revising the current contents of the memory (updating) are crucial factors in memorizing. However, not every individual is able to do so; among them are post-traumatic stress disorder (PTSD) patients who seem to have trouble forgetting trauma-related materials, making their memory overloaded with irrelevant information. The present study assumes that the inability to forget in PTSD patients is due to the impaired updating function of WM and, therefore, suggests that these individuals have inferior WM function for both emotional and unemotional materials. A sample of 30 male veterans with PTSD and 30 healthy individuals (mean age = 46.62, SD = 5.23) participated in the study completing PTSD Checklist, Digit Span Task, and a computerized n-back task. Results revealed that although PTSD subjects showed a generally inferior WM compared with normal individuals; however, their WM performance for emotional and non-emotional stimuli was not significantly different. Supporting the main hypothesis of the study, the findings suggest that a dysfunctional updating function of WM underlies both forgetting and memorizing which affects memory for both emotional and non-emotional material similarly.
