The present study investigated the effects of the use of the right and left hands on haptic identification of letters of the alphabet. Each of the 64 right-handed subjects was given three series of randomly ordered presentations of the 26 letters of the alphabet. The subjects were asked to feel each letter and name correctly each letter as quickly but as accurately as possible. Analysis showed faster identification by those subjects using their left hands on Series 1 with no hand-differences appearing on Series 2 and 3. Significant over-all improvement in identification time occurred with practice. The results were interpreted in terms of a novelty hypothesis of right-hemisphere function and an explanation of perceptual learning of letter identification.
本研究调查了使用右手和左手对触觉识别字母表中字母的影响。64名右利手受试者每人都接受了三组随机排序的26个字母的呈现。要求受试者触摸每个字母，并尽快且尽可能准确地正确说出每个字母的名称。分析表明，在第一组中，使用左手的受试者识别速度更快，而在第二组和第三组中没有出现手的差异。随着练习，识别时间有显著的总体改善。研究结果根据右半球功能的新奇性假说以及字母识别的知觉学习解释进行了解释。
