Abstract

The present study attempted to determine how a rhythmic beat affects ongoing behavior. A regular stimulus beat was presented to normal subjects who had been instructed to push a bar from side to side. Other subjects had been instructed to emit a vocal response. The individual vocal and motor responses became synchronized with the individual beats of the rhythm. The time between stimulus beats determined the modal interresponse time. These results indicate a synchronization effect: ongoing behavior tends to become synchronized with an ongoing stimulus rhythm. An attempt was made to apply these findings to the problem of stuttering, which can be considered as a disturbance of the natural rhythm of speech. Stutterers were instructed to synchronize their speech with a simple regular beat presented to them tactually by a portable apparatus. The result was a reduction of 90% or more of the stuttering for each subject during the period of synchronization. This effect endured for extended periods of spontaneous speech as well as for reading aloud and was found to be attributable to the rhythmic nature of the stimulus and not to other factors.
