This study assessed the effects of the verbally presented stimuli wrong, right, and tree on the frequency of disfluencies during oral reading by 18 school-aged stutterers and 18 matched nonstutterers. No differences were found between the three stimulus words' effect on the disfluency rate of either subject group. Because decreases in the disfluency rates of stutterers were observed during the presentation of all three stimulus words, the data failed to support the operant model. A discussion of theoretical and experimental implications is given.
本研究评估了以口头方式呈现的刺激词“错误”“正确”和“树”对18名学龄期口吃者和18名匹配的非口吃者在朗读时言语不流畅频率的影响。在两个受试组中，未发现这三个刺激词对言语不流畅率的影响存在差异。由于在呈现所有三个刺激词的过程中均观察到口吃者言语不流畅率有所下降，因此数据未能支持操作性模型。文中还对理论和实验意义进行了讨论。
