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 challenges the interpretation of larger error negativity peak amplitudes under accuracy instructions, suggesting they reflect better neuro-cognitive alignment rather than more intense error processing.

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.

The paper introduces a gamified experimental task to assess error awareness by generating a high rate of undetected errors and replicates findings across two studies.

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.

This study investigates temporal discounting in adolescents and adults with Tourette syndrome, finding reduced impulsive choice in adolescents but no differences in adults.
