Abstract

Both subjective distress and cognitive interference have been proposed as mechanisms underlying the negative effects of stress on cognition. Studies of aging have shown that distress is associated with lower cognitive performance, but none have examined the effects of cognitive interference. One hundred eleven older adults (M-sub(age)=80) completed measures of working memory, processing speed, and episodic memory as well as self-report measures of subjective distress and cognitive interference. Cognitive interference was strongly associated with poorer performance on all 3 cognitive constructs, whereas distress was only modestly associated with lower working memory. The results suggest that cognitive process related to stress is an important predictor of cognitive function in advanced age.

摘要

主观痛苦和认知干扰都被认为是压力对认知产生负面影响的潜在机制。衰老研究表明,痛苦与较低的认知表现有关,但尚无研究考察认知干扰的影响。111名老年人(平均年龄80岁)完成了工作记忆、处理速度和情景记忆的测量,以及主观痛苦和认知干扰的自我报告测量。认知干扰与所有三种认知结构的较差表现密切相关,而痛苦仅与较低的工作记忆有适度关联。结果表明,与压力相关的认知过程是高龄认知功能的重要预测因素。
