Several studies have shown that different types of disfluency occur depending on the language production stage at which people experience difficulties. The current study combined a network task and a picture-word interference task to analyse whether lexical-semantic difficulty triggers errors and disfluencies in connected-speech production. The participants produced more disfluencies in the presence of a semantically related distractor word than an unrelated distractor word, while few semantic errors were made. These results support the hypothesis that difficulties at distinct stages of language production lead to distinct patterns of disfluency, with lexical-semantic difficulties leading to self-corrections and silent pauses. The results also have implications for the role of the monitoring system in connected-speech production.
多项研究表明，根据人们遇到困难的语言产生阶段，会出现不同类型的言语不流畅。当前的研究结合了一项网络任务和一项图片-单词干扰任务，以分析词汇-语义困难是否会在连贯言语产生中引发错误和言语不流畅。与无关干扰词相比，参与者在存在语义相关干扰词时产生了更多的言语不流畅，而产生的语义错误较少。这些结果支持了这样一种假设，即语言产生不同阶段的困难会导致不同的言语不流畅模式，词汇-语义困难会导致自我纠正和无声停顿。这些结果也对监测系统在连贯言语产生中的作用具有启示意义。
