智力的年龄差异，反映在WAIS-R性能从20岁到74岁进行了评估，而教育程度保持不变。WAIS-R标准化样本中的7个成年年龄组（从20-24岁到70-74岁），包括1 480名男性和女性，提供了数据来源。采用回归分析和加权平均法对数据进行分析。25-34岁年龄组作为本研究的目标样本;对每个年龄组内每个教育类别的成年人的平均分数进行加权，以匹配25-34岁的教育分布。在对受教育程度进行加权后，平均言语智商随年龄的下降消失了。然而，在20-74岁的范围内，即使在控制了教育之后，表现智商和全面智商仍然下降。教育和11个子测试之间的关系也进行了评估;结果被解释为支持霍恩的流体结晶解释随着年龄的增长，智力的变化。
Age differences in intellect as reflected in WAIS-R performance from age 20 to 74 years were evaluated while educational attainment levels were held constant. The seven adult age groups (ranging from 20-24 to 70-74) in the WAIS-R standarization sample, comprising a sample of 1480 men and women, provided the data source. The data were analyzed using regression analysis and a weighted means approach. The 25-34-year age group served as the target sample for this study; the mean scores for adults in each educational category, within each age group, were weighted to match the educational distribution of ages 25-34. After weighting for education, the decline in mean Verbal IQ from age to age disappeared. However, declines across the 20-74-year range remained for Performance IQ and Full Scale IQ, even after controlling for education. The relationship between education and each of the 11 subtests was also evaluated; the results were interpreted as supportive of Horn''s fluid-crystallized explanation of changes in intelligence with advancing age.
