The Balloon Analogue Risk Task (BART) is a test of risk-taking behaviors in participants.
In the experiment, participants are presented with a balloon. The participant is prompted to inflate the balloon using the Right Arrow key. After successfully inflating the balloon by 1 unit, the participant receives five points. The more the participant inflates the balloon, the more points they receive.
E-Prime randomly selects a number between 1 and 100 for each trial representing the total number of inflated units before the balloon bursts. If the participant inflates the balloon too much, it pops and no points are given. Participants also have the choice to press the Left Arrow to advance the trial while keeping their points. There is one practice trial and 5 critical trials.
