This paper reports the findings of a study investigating the relationship of executive working memory (WM) and phonological short-term memory (PSTM) to fluency and self-repair behavior during an unrehearsed oral task performed by second language (L2) speakers of English at two levels of proficiency, elementary and lower intermediate. Correlational analyses revealed a negative relationship between executive WM and number of pauses in the lower intermediate L2 speakers. However, no reliable association was found in our sample between executive WM or PSTM and self-repair behavior in terms of either frequency or type of self-repair. Taken together, our findings suggest that while executive WM may enhance performance at the conceptualization and formulation stages of the speech production process, self-repair behavior in L2 speakers may depend on factors other than working memory.
本文报告了一项研究的结果，该研究调查了在由两个熟练程度水平（初级和中低级）的英语第二语言（L2）使用者进行的无预演口语任务中，执行性工作记忆（WM）和语音短期记忆（PSTM）与流利度和自我修正行为之间的关系。相关性分析显示，在中低级L2使用者中，执行性WM与停顿次数之间存在负相关关系。然而，在我们的样本中，就自我修正的频率或类型而言，执行性WM或PSTM与自我修正行为之间未发现可靠的关联。综合来看，我们的研究结果表明，虽然执行性WM可能会在言语产生过程的概念化和表述阶段提高表现，但L2使用者的自我修正行为可能取决于工作记忆以外的因素。
