Modeling the effects of schizophrenia and medial–frontal brain stimulation on prediction error electrophysiology and behavior during reinforcement learning. Mean ERN amplitude, RT, and percentage correct accuracy sorted into 10 trial-wide bins from the start of the experiment shown across healthy controls (HC) and patients with schizophrenia (SZ) from the sham (black) and anodal (blue) stimulation conditions. Circles represent empirical results. Lines indicate modeling results: solid line indicates controls; dotted line indicates patients. Error bars indicate ±1 SEM.
