Validated for university students. Using a computerized tool, participants are asked to inflate a balloon on the computer screen. Each click that inflates the balloon accrues $0.05 in a bank visible on the screen. Participants are free to “collect the money” at any point, until the balloon pops, at which point all money accrued goes back to $0.00 and a new balloon appears. Participants get 10 balloons, and the total amount of money collected is reported at the end.
