The performance of male adult stutterers and fluent speakers was compared on repetitive sequential finger tapping and index finger tapping with one hand while carrying out concurrent paced tasks with the other hand. For the theoretically meaningful condition of right-hand sequential tapping and left-hand concurrent task performance, there was more interference on the tapping task among stutterers than fluent speakers. The data were interpreted as being consistent with a neuropsychological model of stuttering that includes as an element enhanced left-hemisphere vulnerability to interference by concurrent right-hemisphere activity.
研究比较了成年男性口吃者和流利说话者在进行重复性顺序手指敲击和单手食指敲击时的表现，同时另一只手执行同步节奏任务。对于右手顺序敲击和左手同步任务表现这一具有理论意义的情况，口吃者在敲击任务中受到的干扰比流利说话者更多。这些数据被解释为与口吃的神经心理学模型一致，该模型包含一个要素，即左半球更容易受到右半球同时活动干扰的影响。
