(A) An illustration of one trial of the social judgment task. The final payoffs for both Player A (the proposer) and Player B (the responder) were presented at the beginning of each trial. After that, in the certain trails, Player A’s initial proposal was revealed. In unknown intention trails, the initial proposal was not revealed (all grey). The example here showed a final payoff of 3¥ (about $0.5) for the proposer, and 9¥ (about $1.5) for the responder (good outcome). The final payoffs were a result of computer reverse procedure as the initial offer was 9¥ (about $1.5) for the proposer and 3¥ (about $0.5) for the responder (bad intention). A seven-point goodness rating scale (1 = very bad, 7 = very good) was employed to indicate the judgment of Player A’s behavior. (B) Illustration of the whole procedure.
