Abstract
The purpose of this study was to investigate the characteristics of the personal tempo of children who stutter. The subjects were a group of thirteen children who stutter severely when engaged in physical activities involving speech and a group of thirteen children who do not stutter. The subjects ranged in age from eight to thirteen. In observing the children's activities, the stutterers showed an initial lack of stability, an improvement in stability when exposed to rhythmic sound stimulus, and a quick synchronous response to the rhythmic sound stimulus. This suggests that there may be children who stutter and also have an unstable personal tempo. More research is needed, however, to establish whether or not unstable personal tempo arises from stuttering.
