PURPOSE
This research aimed to investigate whether demographic factors are similarly related to retrieval of object and proper names.
METHODS
The sample included 5,907 individuals above age 70 who participated in the Health and Retirement Study between 2004 and 2012. Participants were asked to name two objects as well as the US President and Vice President. Latent growth curve models examined the associations of age, education, and self-rated health with baseline levels and change trajectories in retrieval.
RESULTS
Age and education were more strongly related to retrieval of proper names than to retrieval of object names, both for baseline scores and for change trajectory. Similar effects of self-rated health emerged for both types of stimuli.
CONCLUSIONS
The results show that examining object names and proper names together as indication of cognitive status in the HRS might overlook important differences between the two types of stimuli, in both baseline performance and longitudinal change.
目的
本研究旨在调查人口统计学因素与物体名称和专有名称检索之间的关系是否相似。
方法
样本包括5907名70岁以上的个体，他们在2004年至2012年期间参与了健康与退休研究。参与者被要求说出两个物体的名称以及美国总统和副总统的名字。潜在增长曲线模型检验了年龄、教育程度和自评健康状况与检索的基线水平和变化轨迹之间的关联。
结果
对于基线分数和变化轨迹，年龄和教育程度与专有名称检索的相关性比与物体名称检索的相关性更强。两种类型的刺激在自评健康方面都出现了类似的效果。
结论
结果表明，在健康与退休研究中，将物体名称和专有名称一起作为认知状态的指标进行检查，可能会忽略这两种类型刺激在基线表现和纵向变化方面的重要差异。
