Imagining an event from a personal perspective has been found to be able to enhance memory for words and sentences for healthy younger adults and brain-injured patients. However, little is known about how people with amnestic mild cognitive impairment (aMCI) respond to self-imagination, in comparison to healthy older adults. In the current study, participants were asked to process a group of objects using either a self-imagination approach or a baseline strategy in which the self was not heavily involved. Self-imagination shows a mnemonic advantage over the control strategy, though this pattern emerged more clearly for healthy older adults. Furthermore, suggestive evidence indicates that cognitive ability supports self-reference benefits for healthy older adults, but not aMCI patients. These findings extended previous research to reveal the effectiveness of self-imagination for older adults using pictorial stimuli and supported the viewpoint that aMCI could qualitatively change the way that cognitive resources are engaged.
从个人角度想象一个事件已被发现能够增强健康的年轻成年人和脑损伤患者对单词和句子的记忆。然而,与健康的老年人相比,对于有健忘性轻度认知障碍(aMCI)的人如何应对自我想象,我们知之甚少。在当前的研究中,要求参与者使用自我想象方法或不涉及自我的基线策略来处理一组对象。自我想象相对于控制策略表现出记忆优势,尽管这种模式在健康的老年人中更为明显。此外,有迹象表明,认知能力支持健康老年人的自我参照益处,但不支持 aMCI 患者。这些发现扩展了先前的研究,揭示了使用图片刺激对老年人进行自我想象的有效性,并支持了这样一种观点,即 aMCI 可能从质量上改变认知资源的参与方式。
