Transcutaneous Vagus Nerve Stimulation boosts evidence accumulation during perceptual decision-making

This study shows that transcutaneous vagus nerve stimulation (tVNS) improves perceptual decision accuracy by enhancing evidence accumulation, particularly when applied early in a task.

Common Neural Choice Signals reflect Accumulated Evidence, not Confidence

The paper investigates whether neural signals reflect confidence or accumulated evidence, finding that they track evidence rather than confidence directly.

Transcutaneous Vagus Nerve Stimulation Boosts Post-Error Accuracy During Perceptual Decision-Making

This study uses tVNS to investigate the role of the LC-NE system in perceptual decision-making, finding it improves accuracy without affecting reaction times, supporting the gain hypothesis.

Manipulating prior beliefs causally induces under- and overconfidence

The paper shows that manipulating prior beliefs about task performance affects confidence levels in perceptual decisions without changing actual performance.

Modelling Speed-Accuracy Tradeoffs in the Stopping Rule for Confidence Judgments

The paper introduces a new computational model for confidence judgments, showing it better explains speed-accuracy tradeoffs in decision-making than existing models.
