The hypercorrection effect persists over a week, but high-confidence errors return.

Area of Science:

• Cognitive Psychology
• Memory Research
• Learning Sciences

Background:

• Misconceptions are common and resistant to correction.
• The hypercorrection effect shows high-confidence errors are more correctable with feedback.

Purpose of the Study:

• To investigate the persistence of the hypercorrection effect over a 1-week delay.
• To examine how memory for correct answers influences error reproduction after a delay.

Main Methods:

• Participants answered general-knowledge science questions and rated their confidence.
• Feedback was provided, and participants reanswered questions either immediately or after a 1-week delay.

Main Results:

• The hypercorrection effect was observed immediately and after a delay, but error correction decreased over time.
• High-confidence errors were more likely to be reproduced on the delayed test if the correct answer was forgotten.

Conclusions:

• While high-confidence errors are initially more correctable, their persistence depends on memory for the correct information.
• Findings contribute to understanding error correction and memory dynamics, highlighting the dual nature of high-confidence errors.
