通过观察一组口吃者(N=5)在呈现刺激和产生/α/之间的间隔期间的肋骨和腹部半累积的变化，来探讨口吃者发音前胸壁姿势异常的可能性。研究发现，口吃者和之前研究过的一组正常男性的胸壁发音调节模式在本质上是相同的。然而，在实施胸壁调整的过程中，肺容量变化的方式有显著不同。这被认为是口吃者声门关闭延迟的迹象，而不是主要的呼吸障碍的代表。
The possibility that prephonatory chest wall posturing is abnormal in stutterers was explored by observing rib cage and abdominal hemicircumference changes during the interval between the presentation of a stimulus and the production of/alpha/by a group of stutterers (N = 5). It was found that the patterns of chest wall adjustment for phonation were qualitatively identical in the stutterers and in a comparable group of normal men studied previously. There was, however, a significant difference in the way in which lung volume changed during the execution of the chest wall adjustment. This was considered to be indicative of delayed glottal closure among the stutterers rather than representative of a primary ventilatory disturbance.
