The present study investigated the effects of the use of the left and right hands on haptic identification of letters which were presented in either a normal (0 degrees rotation), downward (90 degrees clockwise rotation), upside down (180 degrees rotation), or facing upward (270 degrees rotation) position. Each of the 80 right-handed subjects was given five series of randomly ordered presentations of sets of 8 letters of the alphabet. The subjects were asked to feel and then name each letter correctly as quickly but as accurately as possible. Times showed no effect of hand, but significant effects were found for different sets of letters, degree of rotation and a significant decrease in identification time was observed across the five series. Interactions occurred between hand and rotation as well as set and rotation. Errors showed a significant interaction of hand with degree of rotation; the right was superior at 0 degrees but the left was superior at 90 degrees. The results were discussed in terms of hypotheses of hemisphere function, mental rotation, and stimulus familiarity.
本研究调查了使用左手和右手对触觉识别字母的影响，这些字母以正常（0度旋转）、向下（顺时针90度旋转）、颠倒（180度旋转）或向上（270度旋转）的位置呈现。80名右利手受试者每人都接受了五组随机排列的字母表中8个字母的呈现。受试者被要求触摸并尽可能快速且准确地正确说出每个字母。结果显示，手的使用没有影响，但不同字母组、旋转程度有显著影响，并且在五个系列中观察到识别时间显著减少。手与旋转以及字母组与旋转之间存在交互作用。错误显示出手与旋转程度之间存在显著交互作用；右手在0度时表现更优，但左手在90度时表现更优。根据半球功能、心理旋转和刺激熟悉度的假设对结果进行了讨论。
