Explaining distortions in metacognition with an attractor network model of decision uncertainty

This paper develops a biologically-plausible model of decision uncertainty to explain metacognitive distortions in mental health disorders by linking model parameters to empirical confidence judgments and self-reported symptoms.

Changes-of-mind in the absence of new post-decision evidence

The paper demonstrates that changes-of-mind can occur without new post-decision evidence and links them to prolonged response times and high decision uncertainty.

Neural Circuit Mechanism of Decision Uncertainty and Change-of-Mind

This paper proposes a neuronal circuit model that computes decision uncertainty and explains its role in change-of-mind using behavioural and neural data.
