Naive sighted subjects tested under blind conditions were able to match raised dot (Braille letters) patterns relatively accurately by touch, but showed no advantage in judging identical pairs over different pairs of patterns. This was the case also for letters subjects had been taught to name. Instructions to match on name or feel had significant effects, but these did not relate differentially to "same"/"different" judgments. Under visual conditions subjects matched "same" letters faster than "different" letters. Errors in drawing the letters after tactual exposure and naming training showed that subjects had no accurate idea of the spatial relations or configuration of the dot patterns. The findings suggested that early stages of tactual matching involve exhaustive comparisons and rechecking of features, and that correct notions of tactual dot configurations may be built up rather slowly, and depend on identifying features along orthogonal axes.
在盲视条件下接受测试的未接触过的有视力受试者能够通过触摸相对准确地匹配凸点（盲文字母）图案，但在判断相同图案对与不同图案对时没有优势。对于受试者已学会命名的字母也是如此。根据名称或触觉进行匹配的指令有显著影响，但这些影响与“相同”/“不同”判断没有差异关联。在视觉条件下，受试者匹配“相同”字母的速度比“不同”字母快。在触觉接触和命名训练后绘制字母时出现的错误表明，受试者对凸点图案的空间关系或构型没有准确概念。研究结果表明，触觉匹配的早期阶段涉及对特征的详尽比较和重新检查，并且触觉凸点构型的正确概念可能建立得相当缓慢，并且依赖于沿正交轴识别特征。
