(A) Temporal structure of a single gambling trial. Each trial was divided into 3 phases: an INFORMATION, DECISION and OUTCOME phase. Subjects first received INFORMATION about the sum of money they had accumulated and the bet size, which could be lost. In the DECISION phase, two sets of cards facedown were presented together with the associated monetary reward. Participants chose the set of cards where they believed the “ace of hearts” would be hidden. In the OUTCOME phase, the “ace of hearts” was revealed, providing the subjects a feedback whether they had chosen the right set and won the associated reward or lost the bet. (B) Possible choices with associated risk levels.
