The hypercorrection effect overturned a natural assumption. One would expect that errors made with high confidence would be the hardest to correct — the learner is convinced they are right, and their mistake is deeply rooted. Butterfield and Metcalfe showed the opposite. High-confidence errors, once revealed, are corrected and retained more permanently than low-confidence errors.
The proposed mechanism involves arousal: the surprise of being wrong when you were sure you were right triggers emotional salience (amygdala activation), which in turn modulates hippocampal encoding. The correction gets a neurobiological highlight.
Fluera’s Ghost Map feature operationalises this. After a retrieval attempt, the student’s work is overlaid against an ideal solution. Mismatches pulse visually. The more confident the wrong answer, the more dramatic the reveal — and the more durable the correction.
