FIG. 1.
Behavioral measures: means and standard deviations of the three groups. Upper panels, simple reaction task (SRT): (A) accuracy, and (B) reaction time to visual stimuli. (C) Intra-individual coefficient of variation (ICV) of the reaction time. Middle and lower panels, discriminative reaction task (DRT): (D) false alarms for no-go trials, (E) mean DRT, and (F) ICV. (G) Switch cost for switching from no-go to go trials.
