不流利是言语中常见的现象，通常被认为与生产系统中的困难有关。一个未探讨的问题是，在何种程度上需要抑制，以防止不正确的讲话计划被阐明。因此，我们研究了注意力缺陷/多动障碍（ADHD）参与者的不流利产生，这与抑制功能和反应抑制的缺陷有关（Nigg，2001）。参与者完成了一个句子生产任务，其中他们提出了两个图片和一个动词，他们的任务是产生一个句子。如果抑制在防止不正确的言语计划中发挥作用，我们预计ADHD参与者比非ADHD对照组产生更多的重复和修复不流利。结果显示，ADHD的一种亚型（即，随着任务要求的增加，产生了更多的修复不流利。我们的结论是，生产系统依赖于抑制控制，以防止错误的语言生产。
Disfluency is a common occurrence in speech and is generally thought to be related to difficulty in the production system. One unexplored issue is the extent to which inhibition is required to prevent incorrect speech plans from being articulated. Therefore, we examined disfluency production in participants with attention-deficit/hyperactivity disorder (ADHD), which is linked to deficits in inhibitory function and response suppression (Nigg, 2001). Participants completed a sentence production task in which they were presented with two pictures and a verb and their task was to produce a sentence. If inhibition plays a role in preventing incorrect speech plans, we would expect ADHD participants to produce more repetition and repair disfluencies than would non-ADHD controls. The results showed that one subtype of ADHD (i.e., the combined) produced more repair disfluencies as task demands increased. We conclude that the production system relies on inhibitory control in order to prevent errors in language production.
