手指反应时间与动作时间研究

应用ＤＦＹ－１型动态反应时测试仪，以声音为信号，对３组（打字组、钢琴组、控制组）９０名被试手指的简单反应时间和动作时间进行了测试。结果表明：（１）非利手拇指的反应时间比其它各手指短；（２）利手拇指、食指和中指的动作时间比其它各手指短，且差异显；（３）男女被试手指反应时间差异不显，动作时间差异显；（４）钢琴组被试手指反应时间和动作时间均显快于打字组和控制组被试，但打字组与控制组被试手指反应时

Study on Reaction Time and Movement Time of Fingers

The simple auditory reaction time(RT) and movement time(MT) of fingers of 90 subjects which are divided into three groups (typists, pianists, controls) have been measured by the DFY\|1 dynamic response time testing instrument. The results are as follows:(1)The thumb of no\|preferred hand showed shorter RT than other fingers; (2)The thumb, index and middle fingers of the preferred hand showed significantly shorter MT than other fingers; (3)There is no significant difference in RT of fingers between male and female subjects, but male's MT is significantly shorter than female's; (4)Pianists showed significantly shorter RT and MT than typists and controls, but there is no significant difference between that of typists and controls; (5) The correlation between simple RT and MT of fingers is not significant.
