Figure 1

(a) Illustration of the risky choice task. Each trial of the task consisted of a choice between two options, displayed on the left and right side of the screen. The position of outcomes and probabilities on the top (vs. bottom) of the screen was randomized across trials. Each trial of the choice task was preceded by a 500 ms fixation period. The choice itself was self-paced. Font size in the illustration was increased compared to that in the real experiment to ensure readability. (b) Distribution of numeracy scores in the sample of participants.
