214名年龄在35岁到95岁之间的受试者被赋予一项自由分类任务，要求他们将“相似或相同”的几何刺激归为一类。有一个显着的增加，随着年龄的增长，没有相似性分组的数量，虽然大多数受试者在所有年龄组根据相似性; 24的受试者谁不组根据完全相似的预测试被分为两个实验条件的建模条件中，受试者观察到一个模型组根据完全相似性和控制条件。训练结束后，受试者进行了两次后测--一次是与前测相同的刺激，另一次是不同的几何刺激。在第一个后测显着更完整的相似性分类中得到的建模条件比在控制条件。在第二次后测中，模型组和控制组之间没有显著差异。
214 individuals between the ages of 35 and 95 were given a free classification task in which they were asked to group the geometric stimuli that were “alike or the same” together. There was a significant increase with increasing age in the number of no similarity groupings, although the majority of subjects at all ages grouped according to similarity; 24 of the subjects who did not group according to complete similarity on the pretest were divided into two experimental conditions—a modeling condition in which the subjects observed a model group according to complete similarity and a control condition. After the training session the subjects were given two post-tests—one with stimuli identical to those employed on the pretest and one with a different set of geometric stimuli. On the first post-test significantly more complete similarity classifications were obtained in the modeling condition than in the control condition. There was not a significant difference between the modeling and the control subjects on the second post-test.
