The task structure of the coin-guess task. Participants made predictions for either 3 or 5 raffle tickets (only the $5 trial was shown here as an exemplar). Note for the “Press” screen participants were instructed during NoOp trials to enter their prediction as either “Heads” or “Tails” by pressing either the “H” or “T” key. During Op trials, participants were instructed to randomly press one of the two “R” keys to control for motor activity. ERPs were locked to the Outcome Cue Slide for both Op/NoOp trials (for executive control analyses) and Win/Loss trials that were coded based on their later report on the Response Slide (correct/win vs. incorrect/loss, for reward process analyses).
