Abstract

This paper reports on a study investigating the role of working memory in predicting L2 development under immediate and delayed corrective feedback (CF) conditions. A total of 106 seventh-grade EFL learners were assigned to three groups: Immediate CF, Delayed CF, and Task Only. Each group underwent three treatment sessions during which they performed six focused communicative tasks – two in each session – involving the use of the English past tense. The Immediate CF group received feedback on their erroneous use of the target structure during their task performance in Session 1; the Delayed CF group did not receive feedback until the final treatment session; and the Task Only group performed the communicative tasks without receiving any feedback. Treatment effects were measured through a grammaticality judgement test and an elicited imitation test. Working memory was measured by means of an operation span test. The results revealed that working memory was a significant predictor only of the effects of delayed CF, not those of immediate CF or task only. The findings suggest that delayed CF may have imposed a heavier processing burden on the learners’ working memory due to the need to match the delayed feedback with the errors in their procedural knowledge manifested in previous sessions. Based on the results of this and other empirical studies, the authors argue for the superiority of immediate feedback over delayed feedback.

工作记忆的个体差异与即时和延迟纠正反馈的有效性之间的关系

本文报道了一项关于即时和延迟纠正反馈(CF)条件下工作记忆在预测二语发展中的作用的研究。106名七年级英语学习者被分为三组:即时CF、延迟CF和任务型CF。每一组都接受了三次治疗，在此期间，他们完成了六项重点交际任务——每次两项——涉及英语过去时的使用。即时CF组在第一阶段的任务执行中收到了关于他们错误使用目标结构的反馈;延迟CF组直到最后治疗阶段才收到反馈;而任务组在没有收到任何反馈的情况下执行交流任务。通过语法判断测试和诱导模仿测试来衡量治疗效果。工作记忆采用操作广度测验。结果显示，工作记忆仅是延迟CF的显著预测因子，而不是即时CF或任务的显著预测因子。研究结果表明，延迟CF可能对学习者的工作记忆造成了更重的加工负担，因为学习者需要将延迟反馈与他们在前几次学习中表现出来的程序性知识错误相匹配。基于这一结果和其他实证研究，作者认为即时反馈优于延迟反馈。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
