Fig 1.

(A) A sample stimulus for a pair of risky lotteries posing gains (condition RG). The groups of squares, numbers, and arrows indicate the distribution of red, blue, and yellow marbles in two containers. The numbers below the arrows signify the payoff in dollars of each of the marbles at the arrowhead. After an initial endowment of $190 cash, the participant's task is to choose the container from which one marble would be drawn. The lottery on the left has the lower payoff variance and is considered to be less risky. (B) A sample stimulus contrasting a risky lottery (on the left) and a certainty lottery posing gains (condition CG).
