我们调查了健忘症患者学习新事实的能力（例如，安赫尔福尔斯位于委内瑞拉），以及记住这些事实是在何时何地学习的（即来源记忆）。为了评估事实和源记忆对逆行性遗忘的敏感性，在第一次治疗前向接受电休克治疗的患者介绍事实，并在第二次治疗后进行测试。所有健忘症患者均表现出明显的事实记忆障碍。此外，一些健忘症患者表现出源性健忘症（即，他们回忆起一些事实，但后来不记得这些事实是在哪里或何时学到的）。源性失忆症与记忆缺陷本身的严重程度无关，因为表现出源性失忆症的患者与没有表现出源性失忆症的患者回忆起的事实一样多。这些结果表明，健忘症的缺陷包括在获取和保留新事实方面的障碍。源性遗忘症也可能发生，但它与受损的回忆和识别无关，似乎反映了在记忆获得信息的特定背景时的困难。研究结果进行了讨论，其意义的记忆是如何组织的。（PsycInfo数据库记录（c）2022阿帕，保留所有权利）
We investigated the ability of amnesic patients to learn new facts (eg, Angel Falls is located in Venezuela) and also to remember where and when the facts were learned (ie, source memory). To assess the susceptibility of fact and source memory to retrograde amnesia, patients prescribed electroconvulsive therapy were presented facts prior to the first treatment and were tested after their second treatment. All amnesic patients exhibited marked fact memory impairment. In addition, some amnesic patients exhibited source amnesia (ie, they recalled a few facts but then could not remember where or when those facts had been learned). Source amnesia was unrelated to the severity of the memory deficit itself, because patients who exhibited source amnesia recalled as many facts as the patients who did not. These results show that the deficit in amnesia includes an impairment in acquiring and retaining new facts. Source amnesia can also occur, but it is dissociable from impaired recall and recognition and appears to reflect difficulty in remembering the specific context in which information is acquired. The findings are discussed in terms of their significance for how memory is organized.(PsycInfo Database Record (c) 2022 APA, all rights reserved)
