Thirteen retarded adults at each of three MA levels (5 to 6, 7 to 8, 9 to 12) were assessed on classification relatively, and transitivity performance. Analyses of covariance, with IQ effects factored out, showed significant MA effects for all three tasks (ps less than .01), and analyses of variance across tasks at each MA level also showed significant task effects at each level (ps less than .01). Binomial test analyses of the proportions of subjects performing discrepantly in both directions on each pair of tests were also conducted. The results indicated a sequential order of development of classification, relatively, and transitivity operations, in that order.
对三个心理年龄水平（5至6岁、7至8岁、9至12岁）的每组13名智力迟钝成年人进行了分类相对性和传递性表现的评估。在排除智商影响的协方差分析中，所有三项任务均显示出显著的心理年龄效应（p值小于0.01），并且在每个心理年龄水平上对各项任务进行的方差分析也显示出每个水平上的显著任务效应（p值小于0.01）。还对在每对测试中两个方向表现不一致的受试者比例进行了二项式检验分析。结果表明，分类、相对性和传递性操作的发展顺序依次为上述顺序。
