ABSTRACT

Prospective memory (PM) problems in aging and, to a greater extent, in mild cognitive impairment (MCI), compromise functional independence. This study examined the effectiveness of a cognitive training program based on visual imagery to improve PM among older adults with and without MCI. Participants were older adults, 24 with MCI and 24 cognitively healthy (HOA). Half of them (12 MCI and 12 HOA) were randomly assigned to the PM training program, the other half to the no-training control group. All participants also completed a pre- and post-test evaluation, including neuropsychological tests, questionnaires, and the Ecological Test of Prospective Memory (TEMP). There was no significant effect of the intervention on the TEMP total, event-based or time-based scores for either the MCI or HOA groups. However, the trained MCI group committed fewer false alarms (i.e., more efficient identification of prospective cues) in the event-based condition of the TEMP at post-test. On the other hand, all trained participants performed better than control participants on retrospective memory tests, which suggests that visual imagery-based training is more effective to improve retrospective memory than PM. Possible explanations for these results are explored.

视觉意象训练计划对改善有或没有轻度认知障碍的老年人的前瞻性记忆的有效性:一项随机对照研究

摘要

衰老过程中的前瞻性记忆 (PM) 问题以及更大程度上的轻度认知障碍 (MCI) 会损害功能独立性。本研究检验了基于视觉意象的认知训练计划对改善患有和未患有 MCI 的老年人的 PM 的有效性。参与者是老年人,其中 24 人患有 MCI,24 人认知健康 (HOA)。其中一半(12 名 MCI 和 12 名 HOA)被随机分配到 PM 训练计划,另一半分配到无训练对照组。所有参与者还完成了测试前和测试后评估,包括神经心理学测试、问卷调查和前瞻记忆生态测试 (TEMP)。对于 MCI 或 HOA 组,干预对 TEMP 总分、基于事件的分数或基于时间的分数没有显着影响。然而,受过训练的 MCI 小组在测试后的 TEMP 基于事件的条件下犯了更少的误报(即,更有效地识别预期线索)。另一方面,所有受过训练的参与者在回顾性记忆测试中的表现都优于对照组参与者,这表明基于视觉图像的训练比 PM 更有效地改善回顾性记忆。探讨了对这些结果的可能解释。
