3 A fixed strategy of 64 pumps for each balloon maximizes earnings on the BART (Reference Lejuez, Read, Kahler, Richards, Ramsey, Stuart, Strong and BrownLejuez et al., 2002). With 30 balloons, 15 will explode before 64 pumps, and 15 will explode after 64 pumps. Therefore, only 15 balloons are banked: (0.05 rand per pump)*(64 pumps per balloon)*(15 balloons banked)=R48. Instructions: “Your aim in this task is to win points by pumping the balloon up. You may pump the balloon up as many times as you wish by pressing the ‘Air’ button: every pump will give you more points, but it also increases the risk of the balloon bursting. The speed at which you pump does not affect the likelihood of the balloon bursting. If you burst the balloon you lose the points from that balloon, and this time you also get -200 points. As before, you can stop pumping the balloon up at any point and collect the points you have earnt, by pressing the ‘Collect Points’ button. There are 30 balloons in this block.”
