We re-evaluate conclusions about disfluency production in high-functioning forms of autism spectrum disorder (HFA). Previous studies examined individuals with HFA to address a theoretical question regarding speaker- and listener-oriented disfluencies. Individuals with HFA tend to be self-centric and have poor pragmatic language skills, and should be less likely to produce listener-oriented disfluency. However, previous studies did not account for individual differences variables that affect disfluency. We show that both matched and unmatched controls produce fewer repairs than individuals with HFA. For silent pauses, there was no difference between matched controls and HFA, but both groups produced more than unmatched controls. These results identify limitations in prior research and shed light on the relationship between autism spectrum disorders and disfluent speech.
我们重新评估了高功能自闭症谱系障碍（HFA）中不流畅产生的结论。之前的研究检查了 HFA 个体，以解决关于说话者和听者导向不流畅的理论问题。HFA 个体往往以自我为中心，语用语言技能较差，应该不太可能产生听者导向的不流畅。然而，之前的研究没有考虑到影响不流畅的个体差异变量。我们表明，匹配和不匹配的对照组产生的修复次数都少于 HFA 个体。对于无声停顿，匹配对照组和 HFA 之间没有差异，但两组产生的无声停顿都多于不匹配对照组。这些结果指出了先前研究的局限性，并阐明了自闭症谱系障碍与不流畅言语之间的关系。
