Testing was conducted in a sound-attenuated, dimly lit room, with the stimuli presented centrally on a 21” CRT color monitor at a viewing distance of 100 cm. Participants completed a set of mood and personality questionnaires prior to testing and then performed five tasks (a gambling feedback task, a reinforcement learning task, a Flanker task, a Novelty-Oddball task, and a go/no-go task), the one reported here being the last for each participant. Participants took a brief break after the third task. Together, the recording session lasted between 1.5 and 2 hours. Behavioral responses were made using a PST Serial Response Box and stimuli were delivered using E-Prime 1.1 (Psychology Software Tools, Inc.).
