在平均5.2年的年度随访中,年龄和教育程度相当的老年黑人(n= 647)和白色(n= 647)完成了一系列17项认知测试,从中得出5项能力的综合指标。黑人亚组中每种能力的基线水平较低。情景记忆和工作记忆的下降与种族无关。黑人的语义记忆、感知速度和视觉空间能力的下降比白色人慢,而在语义记忆和感知速度方面,这种影响在老年人中比年轻人强。在调整了重测效应后,种族差异仍然存在。结果表明,黑人和白色人之间的微妙的认知老化的差异。(PsycInfo数据库记录(c)2024阿帕,保留所有权利)
During a mean of 5.2 years of annual follow-up, older Black (n= 647) and White (n= 647) persons of equivalent age and education completed a battery of 17 cognitive tests from which composite measures of 5 abilities were derived. Baseline level of each ability was lower in the Black subgroup. Decline in episodic and working memory was not related to race. Decline in semantic memory, perceptual speed, and visuospatial ability was slower in Black persons than White persons, and in semantic memory and perceptual speed this effect was stronger in older than younger participants. Racial differences persisted after adjustment for retest effects. The results suggest subtle cognitive aging differences between Black persons and White persons.(PsycInfo Database Record (c) 2024 APA, all rights reserved)
