How does error correction occur during lexical learning?

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.

Case of cytomegalovirus-associated direct anti-globulin test-negative autoimmune hemolytic anemia.

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.
