10 adult stutterers and 10 nonstutterers were required to extend as fast as possible their right and left index fingers under isometric conditions in response to an auditory signal. Force developed during finger extension was measured continuously during each trial. From these force records reaction time, contraction time, and peak force were measured. For stutterers, contraction times were longer (about 36 msec.) than for nonstutterers. Possible reasons for this result are discussed.
10名成年口吃者和10名非口吃者被要求在等长条件下，根据听觉信号尽可能快地伸展其右手和左手食指。在每次试验过程中持续测量手指伸展时产生的力量。从这些力量记录中测量反应时间、收缩时间和峰值力量。对于口吃者，收缩时间比非口吃者更长（约36毫秒）。讨论了这一结果的可能原因。
