Fig. 1.

Experimental design. (A) Participants received advice before they were asked to play a four-armed bandit task. Each trial started with the presentation of four card decks, one of which needed to be selected within a maximum of 4 s. Thereafter, the associated feedback was presented. Before a new trial started, a fixation cross was displayed for 1 s. (B) Payoff distribution (i.e., different payoff values on the × axis displayed per frequency on the y axis) and average payoff for the bad decks (in red) and the good decks (in blue). Error bars represent standard errors of the mean. (For interpretation of the references to color in this figure legend, the reader is referred to the Web version of this article.)
