Abstract

The memory impairment of a patient suffering from functional retrograde amnesia was assessed both during the amnesic episode and after its termination. The patient's performance on a task tapping semantic memory was nearly identical on the two test occasions, but his performance on a task tapping episodic memory substantially changed across test sessions. Cueing procedures revealed that in spite of the patient's restricted access to episodic memory during the amnesic period, a relatively intact "island" of episodic memories could be uncovered. The distinction between episodic and semantic memory, as well as the relation between organic and functional retrograde amnesia, are discussed in light of the case study.

摘要

对一名患有功能性逆行性遗忘症患者的记忆障碍，在遗忘发作期间及发作结束后均进行了评估。该患者在一项涉及语义记忆的任务中的表现，在两次测试时几乎相同，但他在一项涉及情景记忆的任务中的表现，在不同测试环节有显著变化。提示程序显示，尽管该患者在遗忘期对情景记忆的 access 受限，但仍能发现一个相对完整的情景记忆“孤岛”。根据该案例研究，对情景记忆和语义记忆之间的区别，以及器质性和功能性逆行性遗忘症之间的关系进行了讨论。
