A previous study found that the Flynn effect accounts for 85% of the normative difference between 20- and 70-year-olds on subtests of the Wechsler intelligence tests. Adjusting scores for the Flynn effect substantially reduces normative age-group differences, but the appropriate amount of adjustment is uncertain. The present study replicates previous findings and employs two other methods of adjusting for the Flynn effect. Averaged across models, results indicate that the Flynn effect accounts for 76% of normative age-group differences on Wechsler IQ subtests. Flynn-effect adjustment reduces the normative age-related decline in IQ from 4.3 to 1.1 IQ points per decade.
先前的一项研究发现，在韦氏智力测验的分测验中，弗林效应解释了 20 岁和 70 岁人群之间的 85%的规范差异。调整分数以适应弗林效应会大大减少规范年龄组之间的差异，但适当的调整量是不确定的。本研究复制了之前的发现，并采用了另外两种适应弗林效应的方法。跨模型平均，结果表明，弗林效应解释了韦氏智商分测验中规范年龄组差异的 76%。弗林效应调整使 IQ 的规范年龄相关下降从每十年 4.3 个 IQ 点减少到 1.1 个 IQ 点。
