Overview of the experimental procedure. Participants completed two experimental sessions on 2 different days with a minimum of 48 h between the sessions. They were pseudorandomly allocated to one of two stimulation orders, receiving either excitatory transcranial Direct Current Stimulation (tDCS) of the vmPFC before gambling in session one and inhibitory tDCS in session two, or vice versa. On the far right, an approximate timeline for the experimental procedure is shown. BDI-II, Beck Depression Inventory-II; RR, Scale for Measuring Reward Responsiveness; UI-18, Intolerance of Uncertainty scale; SDS-CM, Social Desirability Scale by Crowne and Marlowe; SAM-Rating, Subjective Ratings of Hedonic Valence and Emotional Arousal; PANAS, Positive and Negative Affect Schedule.
