(A) Two-step decision task (adapted from Otto et al.85). (First step) Participants must choose between the two images, leading preferentially to a green or a blue screen, according to fixed probabilities. (Second step) Subject choose between the two images linked to probabilities to win money. Those probabilities slowly change with the time and vary according to the screen color. (B) Trial’s design. (C) Second step’s changes in probability of reward. (D) Theoretical decision pattern according to a pure MF strategy or to a pure MB strategy.
