ABSTRACT

We examined two theories of the mechanisms that enable error correction via corrective feedback. One theory focuses on enhancing the encoding of corrective feedback (corrective feedback-encoding facilitation account). The other is the recursive reminding theory, which considers memory integration between an initial event with error generation and a subsequent event involving correct answer feedback. The Japanese idiom pronunciation task was used in two experiments, in which it was manipulated whether the generated errors were visually presented, as well as corrective feedback. In an immediate retest after a five-minute retention interval, participants recalled their errors in the initial test and their correct answers. In addition, error trials fell into three ordinal confidence categories (low, medium, and high). First, a typical hypercorrection was replicated in which higher-confidence errors are more likely to be corrected. However, this was not observed when errors from the initial test were not recalled in the final test, which does not align with the corrective feedback-encoding facilitation account. The second issue was whether additional experience with the generated errors would enhance the error correction. Given the recursive reminding theory, the additional experience of errors should reinforce the mutual dependence between an error and the correct answer provided by feedback, improving cued recall performance later. This prediction is supported. The present findings suggest that the recursive reminding theory can explain the benefits of generating errors when learning through corrective feedback and can also be expanded to understand the hypercorrection effect.

ABSTRACT

A 1-year-old boy developed autoimmune hemolytic anemia after a negative direct anti-globulin test. The concentration of erythrocyte membrane-associated immunoglobulin G, determined using an immunoradiometric assay, correlated with disease activity. He was positive for cytomegalovirus (CMV) both serologically and by quantitative real-time polymerase chain reaction, indicating that his autoimmune hemolytic anemia was directly caused by CMV infection. Since anti-CMV immunoglobulin G was not absorbed by the patient's erythrocytes, cross-reaction between erythrocyte antigens and CMV was not likely a causative factor for hemolysis.
