Timeline of a trial in which probability and magnitude information are separated in time. This is an example of a “Probability First” trial. The probability of winning is shown first (minimum of 2 s up to a button press), which is followed by a variable length blank screen. The magnitude of the stakes is then shown similarly, which is followed by the choice screen, and then the results of the choice. All blank screen durations were variable from 2 – 6 s. “Magnitude first” trials reversed the order of stakes magnitude and probability information. “Simultaneous” trials presented both probability and magnitude on one screen.
