14 normal subjects were given two tactile-recognition tasks. Subjects were asked to match the tactually presented nonsense figures to the visual-recognition display on a Non-rotation task. On the Mental-rotation task subjects matched the tactile figures which were presented in various directions by means of mental rotation to the visual display. A greater superiority of the left hand on the Mental-rotation task was noted while on the Non-rotation task no differences between hands were shown. The right hemisphere may contibute more strongly to higher thought processes especially those which do not need verbal mediation.
14名正常受试者接受了两项触觉识别任务。在非旋转任务中，受试者被要求将触觉呈现的无意义图形与视觉识别显示器上的图形进行匹配。在心理旋转任务中，受试者通过心理旋转将以不同方向呈现的触觉图形与视觉显示器上的图形进行匹配。结果发现，在心理旋转任务中左手具有更大的优势，而在非旋转任务中双手之间没有差异。右半球可能对高级思维过程有更强的贡献，尤其是那些不需要语言中介的思维过程。
