摘要当熟练的打字员敲击一个键时，通常一只手的所有手指都会同时运动。我们研究了各个手指的运动相似程度。受试者被要求输入单词列表，每个单词的设计使得一只手的手指只能按下一个键，其余的字母则用另一只手输入。测量每个手指的长度（屈曲-伸展）和方向（外展-内收）的变化，并通过计算相关系数来评估成对手指运动的相似性。对于每对手指，相关系数分布广泛，但在大多数情况下，平均值显着大于零。相邻手指比非相邻手指表现出更高程度的相关性。当实际用一根手指按键时，相关程度大幅下降。结果表明，在这项熟练的运动任务中，手指通常倾向于一起移动，但当任务需要时，它们可以独立移动。
SummaryWhen skilled typists strike one key, typically all of the fingers of one hand are in motion simultaneously. We studied the extent to which the motion of the individual fingers was similar. Subjects were asked to type lists of words, each word designed so that only one key would be pressed by a finger of one hand, the remaining letters being typed with the other hand. Changes in the lengths (flexion-extension) and orientation (abduction-adduction) of each finger were measured and the similarity of the motion of pairs of fingers was assessed by computing correlation coefficients. For each pair of fingers, the correlation coefficients were broadly distributed, but in most instances the mean was significantly greater than zero. Adjacent fingers showed a higher degree of correlation than did non-adjacent fingers. When one of the fingers was actually used to press the key, the degree of correlation decreased substantially. The results demonstrate that in this skilled motor task, the fingers usually tend to be moved together, but they can be moved independently when the task so requires.
