The hypothesis that letters can be matched on the basis of tactual physical features was tested in three experiments with blind Braille-reading children. Experiment I compared simultaneous matching of pairs of normal (S) and enlarged (E) format Braille letters. Under physical match instructions latencies for SS pairs were significantly faster than for other pairs, but matching EE pairs which compared two difficult letters under physical match instructions was no slower than matching SE or ES letters which compared one easy and one difficult letter under name match instructions. Experiment II showed that successive physical matching of SS and EE letters was significantly faster than name matching of ES and SE letters respectively. Experiment III tested successive matching with two types of altered format (X and Y) under instructions to judge whether pairs were the same letter. Latencies did not differ between XX and YY pairs, but each was significantly faster than either XY or YX pairs. The results were deemed to support the hypothesis.
在针对盲人布莱叶盲文阅读儿童的三项实验中，对字母能否基于触觉物理特征进行匹配这一假设进行了测试。实验一比较了正常（S）格式和放大（E）格式的布莱叶盲文字母对的同时匹配情况。在物理匹配指令下，SS字母对的匹配潜伏期明显快于其他字母对，但在物理匹配指令下比较两个难认字母的EE字母对的匹配速度并不比在名称匹配指令下比较一个易认字母和一个难认字母的SE或ES字母对的匹配速度慢。实验二表明，SS和EE字母的连续物理匹配分别明显快于ES和SE字母的名称匹配。实验三在判断字母对是否为同一字母的指令下，测试了两种改变格式（X和Y）的连续匹配情况。XX和YY字母对之间的潜伏期没有差异，但每一种都明显快于XY或YX字母对。这些结果被认为支持了这一假设。
