The laryngeal premotor, adjustment, and reaction times of 24 stutterers and 24 nonstutterers were assessed by means of a group (2) by stimulus modality (3) by stimulus order (6) factorial investigation. The laryngeal measures were determined from print outs made from electroglottographic recordings taken during the production of [a] that was cued by a visual, auditory, or somato-sensory stimulus. The results revealed that the laryngeal reaction times of stutterers were significantly longer than those of the nonstutterers. Moreover, the reaction times were significantly longer both during the laryngeal premotor and adjustment time periods. The observed between-group difference for each of these laryngeal measures was independent of the stimulus that was employed.
通过一项2（组）×3（刺激方式）×6（刺激顺序）的析因研究，对24名口吃者和24名非口吃者的喉前运动时间、调整时间和反应时间进行了评估。喉部测量数据是根据在视觉、听觉或躯体感觉刺激提示下发出[a]音时所记录的电声门图打印件确定的。结果显示，口吃者的喉部反应时间明显长于非口吃者。此外，在喉前运动和调整时间段内，反应时间也明显更长。在这些喉部测量指标中观察到的组间差异与所采用的刺激无关。
