Modified BART task: A. The BART task. Participants inflate a virtual balloon with each key-press earning them one point. They can press a separate button to cash out on the points earned in each trial, unless they inflate the balloon too much and it “pops”, erasing that balloon’s accumulated points. B. The flankers task. Participants respond to the direction that the center arrow is pointing, ignoring the flanking arrows on both sides of the center arrow. When the center arrow points in the opposite direction than the other arrows, this proportion-incongruent which elicits conflict. C. Modified BART task. We combined the BART and flankers tasks by requiring participants to inflate the balloon with each correct response in the flankers task. Errors deflated the balloon by one pump. The influence of conflict on risky decision making was manipulated by varying the proportion of incongruent flanker trials within each balloon. Participants completed 15 balloons of each of the 5 levels of congruency (10%, 30%, 50%, 70%, 90% incongruent) for a total of 75 balloons.
