Illustrated scheme of the choice under risk and ambiguity (CRA) task. The participant chooses one of two options on either a risky trial (left) or an ambiguous trial (right). A risky option has the amount of reward and a probability of winning the reward indicated by the upper, brown proportion of the box. For an ambiguous option, the probability to win is not explicitly shown but partially blocked by a gray box. On each trial, a risk or ambiguous option is always paired with a fixed (reference) option whose probability of winning the reward is set to 0.5. .
