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).
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.
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.
The data suggest that patients with PTSD may have fairly specific deficits in the monitoring and regulation of memory information.
作者研究了与创伤无关的刺激的广泛记忆功能，以确定诸如侵入性记忆等症状是否可能反映创伤后应激障碍（PTSD）患者中与创伤性记忆的心理内容无关的潜在认知缺陷。
作者使用韦氏成人智力量表（WAIS）测量了20名患有PTSD的男性退伍军人和12名正常对照受试者的智力功能，并使用加利福尼亚言语学习测验评估了他们的记忆表现。
患有PTSD的退伍军人在初始注意力、即时记忆、累积学习以及先前学习的主动干扰等功能方面表现出正常能力。然而，这些退伍军人表现出一种局限性的认知缺陷，表现为存在大量的倒摄干扰，并且在接触插入词表后记忆力显著下降。
数据表明，PTSD患者在记忆信息的监测和调节方面可能存在相当具体的缺陷。
