The relationship between Wechsler Adult Intelligence Scale-Revised (WAIS-R) IQ and performance on measures of memory was examined in 64 adults tested twice at a 2-week interval. Repeated measures analyses of variance revealed that individuals with Low-Average WAIS-R Full Scale IQ scores performed significantly more poorly than did individuals with Average and High-Average Full Scale IQs on memory measures including the Wechsler Memory Scale-Revised (WMS-R) General Memory and Delayed Recall indices, as well as California Verbal Learning Test (CVLT) Total Words. Learning Slope, and Discriminability. Although all three groups demonstrated significant practice effects on each memory measure, group differences in performance persisted at retest. Multiple regression analyses revealed that WAIS-R factor scores Verbal Comprehension and Freedom from Distractibility accounted for up to 42% of the variance in WMS-R and CVLT indices. Moreover, WAIS-R performance at initial testing accounted for 22-41% of the variance in memory performance at retest. These results are discussed in the context of the construct stabilities of intelligence and memory, as well as the psychometric precision of the tests used to measure these constructs.
对64名成年人进行了研究，他们在两周的间隔内接受了两次测试，以检验韦氏成人智力量表修订版（WAIS-R）智商与记忆测量表现之间的关系。重复测量方差分析显示，在包括韦氏记忆量表修订版（WMS-R）一般记忆和延迟回忆指数以及加利福尼亚言语学习测试（CVLT）总单词数、学习斜率和辨别力在内的记忆测量中，WAIS-R全量表智商得分处于低平均水平的个体表现明显比全量表智商处于平均水平和高平均水平的个体差。尽管所有三组在每项记忆测量上都表现出显著的练习效应，但在复测时表现上的组间差异仍然存在。多元回归分析显示，WAIS-R因子得分言语理解和不受干扰性占WMS-R和CVLT指数方差的42%。此外，初次测试时的WAIS-R表现占复测时记忆表现方差的22%-41%。这些结果在智力和记忆的结构稳定性以及用于测量这些结构的测试的心理测量精度的背景下进行了讨论。
