Abstract
Objectives: Perceived discrimination is associated with racial cognitive health disparities. Links between discrimination and cognitive performance, like working memory, in everyday settings (i.e. ambulatory performance) require investigation. Depressive symptoms may be a mechanism through which discrimination relates to ambulatory working memory.
Method: Discrimination, retrospective and momentary depressive symptoms/mood, and aggregated and momentary working memory performance among older Black and White adults were examined within the Einstein Aging Study.
Results: Racially stratified analyses revealed that discrimination did not relate to Black or White adults' ambulatory working memory. Among Black adults, however, more frequent discrimination was associated with greater retrospectively reported depressive symptoms, which related to more working memory errors across two weeks (indirect effect p < 0.05). This path was not significant among White adults. Links between discrimination and momentary working memory were not explained by momentary reports of depressed mood for Black or White adults.
Conclusion: Depressive symptoms may play an important role in the link between discrimination and ambulatory working memory among Black adults across extended measurements, but not at the momentary level. Future research should address ambulatory cognition and momentary reports of discrimination and depression to better understand how to minimize cognitive health disparities associated with discrimination.
目标：感知到的歧视与种族认知健康差异有关。需要对歧视与日常环境中认知能力（如工作记忆）之间的联系进行调查。抑郁症状可能是歧视与非机动工作记忆相关的一种机制：方法：在爱因斯坦老龄化研究（Einstein Aging Study）中对黑人和白人老年人的歧视、回顾性和瞬间抑郁症状/情绪以及综合和瞬间工作记忆能力进行了研究：结果：种族分层分析表明，歧视与黑人或白人的动态工作记忆无关。然而，在黑人成年人中，更频繁的歧视与更多的抑郁症状有关，而抑郁症状与两周内更多的工作记忆错误有关（间接效应 p 结论：抑郁症状可能是影响工作记忆的重要因素：在黑人成年人中，抑郁症状可能在长时间测量中对歧视与流动工作记忆之间的联系起着重要作用，但在瞬间水平上却不是。未来的研究应针对动态认知以及歧视和抑郁的瞬间报告，以更好地了解如何最大限度地减少与歧视相关的认知健康差异。
期刊介绍：
Aging & Mental Health provides a leading international forum for the rapidly expanding field which investigates the relationship between the aging process and mental health. The journal addresses the mental changes associated with normal and abnormal or pathological aging, as well as the psychological and psychiatric problems of the aging population. The journal also has a strong commitment to interdisciplinary and innovative approaches that explore new topics and methods.
Aging & Mental Health covers the biological, psychological and social aspects of aging as they relate to mental health. In particular it encourages an integrated approach for examining various biopsychosocial processes and etiological factors associated with psychological changes in the elderly. It also emphasizes the various strategies, therapies and services which may be directed at improving the mental health of the elderly and their families. In this way the journal promotes a strong alliance among the theoretical, experimental and applied sciences across a range of issues affecting mental health and aging. The emphasis of the journal is on rigorous quantitative, and qualitative, research and, high quality innovative studies on emerging topics.
