目的：研究创伤后应激障碍（PTSD）患者对与创伤无关的刺激的记忆功能，以确定侵入性记忆等症状是否反映了与创伤记忆的心理内容无关的潜在认知缺陷。方法作者使用WAIS测量了20名患有PTSD的男性退伍军人和12名正常对照者的智力功能，并使用加州言语学习测试评估了他们的记忆表现。结果退伍军人PTSD患者在初始注意、即时记忆、累积学习和主动干预先前学习等方面的能力正常。然而，这些退伍军人表现出有限的认知缺陷，表现为大量的回溯干扰的存在，并揭示了一个显着的递减后，暴露于干预单词列表的保留。结论PTSD患者在记忆信息的监测和调节方面可能存在相当特异性的缺陷。
OBJECTIVE The authors investigated a broad range of memory functions for stimuli unrelated to trauma to determine whether symptoms such as intrusive memories might reflect an underlying cognitive deficit unrelated to the psychological content of the traumatic memory in patients with posttraumatic stress disorder (PTSD). METHOD The authors measured the intellectual functioning of 20 male combat veterans with PTSD and 12 normal comparison subjects using the WAIS and evaluated them for performance on memory using the California Verbal Learning Test. RESULTS Veterans with PTSD showed normal abilities in the functions of initial attention, immediate memory, cumulative learning, and active interference from previous learning. However, these veterans showed a circumscribed cognitive deficit, manifested by the presence of substantial retroactive interference and revealed by a significant decrement in retention following exposure to an intervening word list. CONCLUSIONS The data suggest that patients with PTSD may have fairly specific deficits in the monitoring and regulation of memory information.
