ABSTRACT

Objective

Accurate insight into one’s abilities facilitates engagement in rehabilitation and implementation of compensatory strategies. In this study, self-awareness, self-monitoring, and a new self-updating construct of insight were examined in amnestic mild cognitive impairment (aMCI).

Method

Individuals with aMCI and healthy older adults (HOAs) completed a list-learning task in a laboratory setting, and a naturalistic task of everyday functioning in a campus apartment along with other standardized neuropsychological tests. Participants made predictions about performance on the memory and functional tasks prior to task experience (self-awareness), immediately after task experience (self-monitoring), and after a delay (self-updating).

Results

Individuals with aMCI performed more poorly than HOAs on the memory task and other neuropsychological tests but not the functional task. For both the memory and functional task, performance predictions and prediction accuracy measures revealed that the aMCI group exhibited intact self-awareness, self-monitoring, and self-updating. Prediction accuracy measures showed some association with an executive composite but not a memory composite.

Discussion

Participants with aMCI demonstrated intact self-awareness, self-monitoring, and self-updating for a memory and functional task despite exhibiting poorer performance on neurocognitive tests compared to HOAs. These findings suggest that, even as memory in aMCI degrades, executive abilities may help sustain insight into difficulties, enabling adoption of cognitive strategies to support difficulties.

深入了解遗忘型轻度认知障碍患者的记忆和功能能力。

摘要

客观的

准确了解自己的能力有助于参与康复和实施补偿策略。在这项研究中，在遗忘型轻度认知障碍 (aMCI) 中检查了自我意识、自我监控和新的自我更新洞察力结构。

方法

患有 aMCI 和健康老年人 (HOA) 的个体在实验室环境中完成了列表学习任务，以及在校园公寓中完成日常功能的自然主义任务以及其他标准化的神经心理学测试。参与者在任务体验之前（自我意识）、任务体验之后（自我监控）和延迟之后（自我更新）对记忆和功能性任务的表现进行了预测。

结果

aMCI 患者在记忆任务和其他神经心理学测试上的表现比 HOA 差，但在功能性任务上则不然。对于记忆和功能任务，性能预测和预测准确性测量表明，aMCI 组表现出完整的自我意识、自我监控和自我更新。预测准确性测量显示与执行复合材料有一定关联，但与记忆复合材料无关。

讨论

尽管与 HOA 相比，aMCI 的参与者在神经认知测试中表现较差，但他们表现出完整的自我意识、自我监控和自我更新的记忆和功能任务。这些研究结果表明，即使 aMCI 中的记忆力下降，执行能力也可能有助于维持对困难的洞察力，从而能够采用认知策略来支持困难。
