Eight adult male stutterers with Down's syndrome (DS) were compared with a matched group of fluent speakers with DS on verbal and manual motor production tasks at two levels of complexity. The simpler tasks involved diadochokinetic rate (syllable repetition) and finger tapping; the more complex tasks involved the imitation of sentences and placing pegs in the grooved pegboard. On both verbal and manual tasks, stutterers were faster on the simpler but slower on the more complex tasks than were the fluent speakers. The findings suggest that stutterers with DS have a different motor organization than fluent speakers with DS.
八名患有唐氏综合征（DS）的成年男性口吃者与一组匹配的患有DS的流利说话者在两个复杂程度水平的言语和手动运动产生任务上进行了比较。较简单的任务包括重复率（音节重复）和手指敲击；较复杂的任务包括句子模仿和将钉子插入有槽的钉板。在言语和手动任务上，口吃者在较简单任务上比流利说话者更快，但在较复杂任务上更慢。研究结果表明，患有DS的口吃者与患有DS的流利说话者具有不同的运动组织。
