Schematic representation of the Reward Task, based on the Monetary Incentive Delay Task (Knutson et al., 2001a). Trials were potentially rewarding or neutral, as indicated by a cue at the start of the trial. Participants were instructed to respond as fast as possible to the target by pressing a button, irrespective of cue type. Subsequent feedback notified participants of their performance and indicated if they had earned money, as well as their cumulative total at that moment. Target duration was individually adjusted to ensure that each participant could succeed in 50% of the trials.
