The paper shows that pupil dilation during decision-making reflects context-dependent information gain, linking it to prediction error signals in associative learning.

This study empirically distinguishes Bayesian model updating and revision by analyzing prediction error dynamics during learning tasks.

This study compares 7 T and 3 T fMRI responses in human brain regions during a decision-making task, finding greater 7 T benefits in subcortical areas like the brainstem.

The paper shows that pupil responses reflect internal belief states during perceptual decisions, scaling with decision confidence and prediction errors.
