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.
