Measurements of lingual two-point discrimination, oral form discrimination, and alternate motion rate of the tongue were made in 15 children who had normal articulation, 15 children who misarticulated /s/, and 15 children who misarticulated /r/. The two groups of children with misarticulations were found to differ from each other as well as from normal children on various aspects of oral sensation and motor abilities. These findings are interpreted as evidence for the existence of different bases for the misarticulations of the two disordered groups.
对15名发音正常的儿童、15名发/s/音错误的儿童和15名发/r/音错误的儿童进行了舌两点辨别觉、口腔形态辨别觉和舌交替运动速率的测量。结果发现，两组发音错误的儿童在口腔感觉和运动能力的各个方面与正常儿童以及彼此之间均存在差异。这些发现被解释为这两组发音障碍存在不同病因的证据。
