Neural response time (NRT) was compared for 12 adult stutterers and 12 matched normal speakers on two verbal tasks (production of /pae/ and /bae/) and one oral, nonverbal task (lip closure) in response to visual and auditory stimulation. The auditory response stimulus was presented separately to the left and right ears, and the visual stimulus to both eyes. NRT was defined as the time interval between stimulus offset and the onset of electromyographic (EMG) activity from orbicularis oris superior muscle. Results show, in general, that stutterers are slower in NRT for all response tasks in both stimulus modes. Significant differences were found, however, for only the auditory mode. Analyses of the differences between and within groups for response tasks and stimulus modes are discussed in terms of recent research in and theory of timing disturbances in stuttering.
对12名成年口吃者和12名匹配的正常说话者在两项言语任务（发出/pae/和/bae/）和一项口腔非言语任务（唇部闭合）中，针对视觉和听觉刺激的神经反应时间（NRT）进行了比较。听觉反应刺激分别呈现给左耳和右耳，视觉刺激呈现给双眼。NRT被定义为刺激终止与口轮匝肌上部肌电图（EMG）活动开始之间的时间间隔。结果总体显示，在两种刺激模式下，口吃者在所有反应任务中的NRT都较慢。然而，仅在听觉模式下发现了显著差异。根据近期关于口吃时间紊乱的研究和理论，讨论了反应任务和刺激模式在组间和组内差异的分析。
