ABSTRACT

The Cognitive Reserve (CR) hypothesis accounts for individual differences in vulnerability to age- or pathological-related brain changes. It suggests lifetime influences (e.g., education) increase the effectiveness of cognitive processing in later life. While evidence suggests CR proxies predict cognitive performance in older age, it is less clear whether CR proxies attenuate age-related decline on social cognitive tasks. This study investigated the effect of CR proxies on unimodal and cross-modal emotion identification. Sixty-six older adults aged 60–78 years were assessed on CR proxies (Cognitive Reserve Index Questionnaire, NART), unimodal(faces only, voices only), and cross-modal (faces and voices combined) emotion recognition and executive function (Stroop Test). No CR proxy predicted performance on emotion recognition. However, NART IQ predicted performance on the Stroop test; higher NART IQ was associated with better performance. The current study suggests CR proxies do not predict performance on social cognition tests but do predict performance on cognitive tasks.

摘要

认知储备（CR）假说解释了与年龄或病理相关的大脑变化的脆弱性的个体差异。它表明一生的影响（例如教育）可以提高晚年认知处理的有效性。虽然有证据表明 CR 代理可以预测老年时的认知表现，但 CR 代理是否能减轻与年龄相关的社交认知任务下降尚不清楚。本研究调查了 CR 代理对单模态和跨模态情绪识别的影响。对 66 名 60-78 岁的老年人进行了 CR 代理（认知储备指数问卷，NART）、单模态（仅面部、仅声音）和跨模态（面部和声音相结合）情绪识别和执行功能（Stroop）的评估。测试）。没有 CR 代理预测情绪识别的表现。然而，NART IQ 预测了 Stroop 测试的表现；NART IQ 越高，表现越好。目前的研究表明，CR 代理不能预测社会认知测试的表现，但可以预测认知任务的表现。
