Behavioral results.

<p>All error bars are 1 s.e.m. A. Emotion bias for each group. B. Evidence vs. choice curve showing increased selection of happy faces when evidence supports angry face. C. Percent correct for each group.</p

Learning from positive vs. negative feedback.

<p>Error bars show 1 s.e.m. A. Parameter values from the Bayesian model in PD+ICBs. B. Parameter values in PDs.</p

Demographic characteristics.

<p>UPDRS = Unified Parkinson's Disease Rating Scale; LEU = L-dopa equivalent units; DA = dopamine agonists. All values are mean ± SD. Significant differences are labelled with “*”. P-values refer to columns indicated in brackets. Controls (column 1), PD+ICB (column 2), PD−ICB (column 3).</p

Active information sampling and irrational decisions compared between groups.

<p>Fig 1A. Drawing of beads and irrational decision making. Fig 1B. (RLS-AUG = RLS patients without augmentation; RLS+AUG = RLS patients with augmentation; HC = healthy controls). Box plot showing the median (horizontal line) within a box containing the central 50% of the observations (i.e., the upper and lower limits of the box are the 75^th and the 25^th percentiles) and extremes of the whiskers containing the central 95% of the ordered observations. Outliners are shown as circles.</p
