Fig. 4: Modeling parameters per subject.

The learning rate α was significantly lower in the amisulpride group than in the placebo group and tended to be lower, compared to the propranolol group (A). Neither the temperature parameter β, nor the choice bias c differed between the experimental groups (B, C), error bars represent standard errors of the mean, * for p < 0.05,• for p < 0.06.
