对字母混淆矩阵的分析产生了根据被认为包含它们的字符的易混淆性定义的特征列表。因此，低混淆性的相同形状共享很少或没有特征。几位研究人员已经观察到特征提取与同时呈现的易混淆形状的相互抑制。在目前的实验中观察到的相互抑制提供了一个定义的功能，在方向无关的结构关系的基础。在第一个实验中，4个字母数字字符分别与同一组中的另一个字符混淆;当另一组通过重新定位这些相同的形状来形成不同的字符时，这些混淆消失了。在第二个实验中，每组中的人物被成对地暴露在不同的[人类]受试者组中。如果一对中的成员在形状上相似（不考虑方向），识别的准确性就比不相似的情况差。相同方向上的相似形状并不比不同方向上的相似形状更明显地相互抑制。
Analyses of alphabetic confusion matrices have produced feature lists defined in terms of confusability of characters thought to contain them. Identical shapes of low confusability therefore share few or no features. Several researchers have observed mutual inhibition of feature extraction with simultaneously presented confusable shapes. Mutual inhibition observed in the current experiments provides a basis for a definition of features in terms of orientation-independent structural relationships. In the 1st experiment, 4 alphanumeric characters were each confused with 1 other character in this same set; when another set was formed by reorienting some of these same shapes to become different characters, these confusions disappeared. In the 2nd experiment, characters within each set were exposed parafoveally in pairs to different groups of [human] subjects. If members of a pair were similar in shape (disregarding orientation), identification accuracy was poorer than if they were not. Similar shapes in the same orientation were not significantly more mutually inhibiting than similar shapes in different orientations.
