Schematic diagram of the Monetary Incentive Delay (MID) task used in the current study. Participants began each trial presented with 1 of 7 reward cues indicating whether they had an opportunity to gain reward, lose reward, or experience no change if they successfully pressed a button before a visual target disappeared on the screen. After the trial cue presentation, participants fixated on a centered cross-hair while waiting for the target to appear (anticipatory delay). The target would then appear for a variable amount of time during which subjects would attempt to press a button before the target disappeared. Afterwards, subjects received feedback as to whether or not they had been successful, and what the monetary outcome was for the trial.
