This study evaluated cross-sectional and longitudinal age relationships, after age 60, for three subtests of the Wechsler Memory Scale: logical memory, associate learning, and visual reproduction. Cross-sectional regression analyses indicated that age, sex, race, and education accounted for approximately 20 to 35% of the variance in test scores, with education the strongest predictor. Longitudinally, consistent linear declines were found only for hard associates and visual reproduction. Visual reproduction was related more consistently and strongly to age than the two verbal subtests. The effects of selective attrition from the study were discussed.
本研究评估了60岁以后韦氏记忆量表三个分测验(逻辑记忆、联想学习和视觉再现)的横断面和纵向年龄关系。横断面回归分析表明,年龄、性别、种族和教育程度解释了测验分数中约20%至35%的方差,其中教育程度是最强的预测因素。纵向来看,仅在困难联想和视觉再现方面发现了一致的线性下降。与两个言语分测验相比,视觉再现与年龄的关系更为一致和密切。文中还讨论了研究中选择性损耗的影响。
