Experiment 1—Proportion of risky choices taken as a function of the choice framing (gains vs. losses) and the time-pressure condition.
Error bars indicate standard errors of the mean.

Experiment 1—Proportion of risky choices taken for differing levels of pdesirable and payoff variability.

Illustration of the sampling procedure in experience-based risky financial choice task.
Here the participant samples a total of four times, seeing −$4.00 and $0 twice each. From this they may conclude there is a 50% chance of losing $4.00 and a 50% chance of losing nothing. The participant decided to choose the risky option and is shown the result, a loss of $4.00.
