重铸是一种重要的内隐负反馈类型，在母语研究和二语习得研究中备受关注。重铸在面对面互动中的效用已经得到了实证证明，重铸的偶然性被认为是关键。然而，重铸在计算机中介沟通（CMC）中的有效性，特别是基于文本的在线聊天，仍然值得怀疑，因为在CMC话语中常见的“分裂协商例程”中可能违反了这一偶然性因素。本研究采用重复测量设计来检验重铸的偶然性对重铸注意的潜在影响，以及可能介导重铸注意的偶然性效应的一些情境因素。在这项研究中，17名ESL学习者被邀请与一位研究人员就两种二元交流任务进行交谈，一种是预写，另一种是不写。大声思考方案和刺激回忆被用来测量重铸的注意。研究发现，参与者注意到偶然重铸的频率明显高于非偶然重铸。此外，工作记忆和预写对偶然性效应有中介作用，学习者熟练程度对重铸的注意没有中介作用。
Recasts are an important type of implicit negative feedback that has attracted much attention in both L1 research and SLA research. The utility of recasts in face-to-face interaction has been empirically established, and the contingency of recasts is argued to be the key. However, the efficacy of recasts in computer-mediated communication (CMC), text-based online chatting in particular, remains questionable due to the possible violation of this contingency factor in the "split negotiation routines" commonly observed in CMC discourse. This study used a repeated-measure design to examine the potential impact of the contingency of recasts on noticing as well as some contextual factors that might mediate the contingency effect on the noticing of recasts. In this study, 17 ESL learners were invited to chat with one researcher on two dyadic communication tasks, one preceded by prewriting and the other without. Think aloud protocols and stimulated recalls were used to measure the noticing of recasts. It was found that participants noticed contingent recasts significantly more often than noncontingent recasts. Furthermore, working memory and prewriting were found to mediate the contingency effect, and learner proficiency level was found neither pertinent to the noticing of recasts nor mediative of the contingency effect.
