The constancy of interstress intervals (ISIs) was studied in the fluent speech of 2 people who stutter during five adaptation trials. Counter to prediction, ISI constancy did not improve as an accompaniment to the reduction of stuttering from Readings 1-5. Overall, the subjects' ISIs were substantially more variable in duration than those of 2 nonstutterers. This was accounted for by the subjects' unusually long ISIs in utterances that placed greater demands on speech motor control processes. Implications for impairment source factors in stuttering are discussed.
在五次适应性试验中，对两名口吃者流畅言语中的应激间隔（ISI）稳定性进行了研究。与预测相反，ISI稳定性并未随着口吃从第1次阅读到第5次阅读的减少而提高。总体而言，受试者的ISI持续时间比两名非口吃者的ISI持续时间变化大得多。这是由于受试者在对言语运动控制过程要求更高的话语中ISI异常长。文中讨论了对口吃损伤源因素的影响。
