Thirty-six boys and 36 girls at each of two grade levels (second and fourth) were presented with a two-choice simultaneous form discrimination. The forms were five- or 10-sided, and symmetrical or asymmetrical. Ss received either a uniform array (both stimuli symmetrical or asymmetrical) or a mixed array (one stimulus symmetrical and the other asymmetrical). Boys performed better than girls, and older children were more accurate than younger ones. Several interactions among sex, age, and stimulus variables were obtained. The findings indicate sex differences in the development of the ability to process form information.
在两个年级水平（二年级和四年级）上，分别向36名男孩和36名女孩呈现了一种二选一的同时性图形辨别任务。图形有五边形或十边形，且对称或不对称。被试接受的刺激阵列要么是一致的（两个刺激都是对称的或不对称的），要么是混合的（一个刺激对称而另一个不对称）。男孩的表现优于女孩，年龄较大的孩子比年龄较小的孩子更准确。还发现了性别、年龄和刺激变量之间的几种交互作用。这些结果表明在处理图形信息能力的发展上存在性别差异。
