Perceptual Metacognition

After each perceptual decision you rate your confidence; the analysis asks how well that confidence tracks whether you were actually correct.

The link between accuracy and confidence — high sensitivity means you are right more often exactly when you feel more sure, sometimes formalized as meta-d'.

Yes — confidence and accuracy dissociate under time pressure and noise, and overconfidence on difficult trials is a stable research finding.

Metacognitive sensitivity underpins learning, error monitoring, and self-regulation, and it varies partly independently of raw task performance.
