The associations between individual differences in working memory and the effectiveness of immediate and delayed
corrective feedback
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 judgment 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.
