a Schematic of two representative trials of the two-arm bandit task. Participants were cued to select a card from one of two decks (orange or purple) on each trial, then provided with feedback and a trial-unique face image, followed by a fixation cross. b Probability of drawing from the male (orange) or female (purple) decks as a function of trial and reward block (mean reversal trial indicated by vertical lines). Shaded lines denote a 95% confidence interval. c Schematic of the representative trial of the recognition memory task. Participants were presented with images of faces, and instructed to decide whether the images were old or novel lures. Participants then had to indicate their confidence in their selection, followed by a fixation cross. d Probability of a successful subsequent recognition (hit) for each image seen during the decision-making task, as a function of decision-making trial (mean reversal trial indicated by vertical lines). Shaded lines denote a 95% confidence interval.
