其目的是确定向后看的句子处理是如何受到典型的不流利与口吃的讲话。两组听众分别听到花园小径（GP）和控制句子。GP句子在歧义动词前没有不流利、无声停顿或充满停顿。其中一组的句子中还包含了类似口吃的不流利。理解准确性，事件相关电位（ERP）的时间锁定到消除歧义的动词，和感性的扬声器评级，组之间进行了比较。口吃组认为说话者能力较差，但对GP句子的理解准确性更好。排除GP句中动词歧义的ERP包括一个P600成分，索引向后看的句子处理，但仅适用于无口吃组。其他ERP组件，引起GP的句子与沉默/填补停顿，没有组间差异。结果表明，听众放弃先前的期望时，处理含有口吃样的不流利的句子，可能是因为他们缺乏一个扬声器模型定义的口吃的存在。
The aim was to determine how backward-looking sentence processing is affected by typically disfluent versus stuttered speech. Two listener groups heard Garden Path (GP) and control sentences. GP sentences contained no disfluency, a silent pause, or a filled pause before the disambiguating verb. For one group, the sentence preambles additionally contained stuttering-like disfluencies. Comprehension accuracy, event-related potentials (ERPs) time-locked to disambiguating verbs, and perceptual speaker ratings, were compared between groups. The With Stuttering group perceived the speaker as less competent but had better comprehension accuracy for GP sentences. ERPs to disambiguating verbs in GP sentences included a P600 component, indexing backward-looking sentence processing, but only for the No Stuttering group. Other ERP components, elicited to GP sentences with silent/filled pauses, did not differ between groups. Results suggest that listeners abandon prior expectations when processing sentences containing stuttering-like disfluencies, possibly because they lack a speaker model defined by the presence of stuttering.
