在一个双任务范式中，受试者进行了跟踪任务结合不同复杂性的语音任务，我们测试了两个假设涉及注意力的概念口吃。“过载”假说认为口吃与言语产生过程的自动化不足有关，因此过于依赖注意力控制。相反，“回归”假说则假定言语产生是正常的自动化，但假设在某些情况下口吃者会回归到一种受控制的言语产生方式，从而导致口吃。11名口吃者和11名非口吃者参加了实验。总的来说，口吃者在同时说话和执行跟踪任务时表现出的不流利程度要比他们只执行语音任务时少。这种效果是最强的自发讲话时产生的。这一结果支持“回归”假说。 然而，发现一个更复杂的语音任务产生更多的不流利支持“超载”的假设。
In a dual-task paradigm in which subjects performed a tracking task in combination with speech tasks of varying complexity, we tested two hypotheses concerning stuttering involving the concept of attention. The "overload" hypothesis assumes that stuttering is related to insufficient automatization of the speech production process, which consequently relies too much on attentional control. The "regression" hypothesis, in contrast, presupposes that speech production is normally automatized, but assumes that under certain circumstances the stutterer regresses to a controlled way of speech production, which results in stuttering. Eleven stutterers and 11 nonstutterers participated in the experiment. In general, stutterers showed fewer disfluencies while simultaneously speaking and performing a tracking task than they showed when performing the speech tasks only. This effect was strongest when spontaneous speech was to be generated. This result supports the "regression" hypothesis. However, the finding that a more complex speech task yielded more disfluencies supports the "overload" hypothesis.
