This study investigates ERP correlates of confidence during decision formation in a perceptual judgment task and finds that higher confidence is associated with larger CPP amplitudes, independent of relative evidence.

The paper examines how confidence judgments relate to response dynamics across the adult lifespan, finding age-dependent changes in these associations.

The paper investigates how absolute evidence magnitude affects decision accuracy and confidence in perceptual judgments, finding that higher absolute evidence reduces accuracy but increases confidence.

This study examines how metacognitive accuracy changes with age using ERPs, finding a decline in accuracy beyond task performance decline, while behavioral adaptation remains intact.
