Memory impairment is among the most common cognitive deficits in people with multiple sclerosis (MS). To remediate this problem, recent research has evaluated the benefits of self-generated encoding. These nascent investigations reveal that people with MS who have mild memory impairment demonstrate a significant memory benefit from self-generated encoding compared with didactic learning. To extend prior research, the present experiment included MS patients with moderate-severe, rather than just mild, memory impairment. Additionally, the experiment evaluated whether self-generated encoding improves memory for activities of daily living instead of abstract words. Specifically, the experiment determined whether self-generated encoding enhanced memory for names, appointments, and object locations. In agreement with and extending prior research, MS patients remembered more information if it was self-generated rather than didactically presented, and this finding occurred despite moderate-severe memory impairment. Furthermore, compared with didactic encoding, self-generation enhanced recall of activities of daily living. Implications of these findings for cognitive rehabilitation and the nature of memory impairment in MS are discussed.
记忆障碍是多发性硬化症(MS)患者中最常见的认知缺陷之一。为了纠正这一问题,最近的研究评估了自我生成编码的益处。这些新的研究表明,与传统学习相比,患有轻度记忆障碍的MS患者通过自我生成编码在记忆方面有显著益处。为了扩展先前的研究,本实验纳入了患有中度至重度而非仅轻度记忆障碍的MS患者。此外,该实验评估了自我生成编码是否能改善对日常生活活动的记忆,而非抽象词汇的记忆。具体而言,该实验确定自我生成编码是否增强了对姓名、预约和物品位置的记忆。与先前的研究一致并有所扩展,尽管存在中度至重度记忆障碍,但如果信息是自我生成的而非通过传统方式呈现,MS患者能记住更多信息。此外,与传统编码相比,自我生成增强了对日常生活活动的回忆。本文讨论了这些发现对认知康复以及MS中记忆障碍本质的意义。
