a. Acceptance rates in percent categorized according the amount of money offered to the subject. Furthermore, acceptance rates for fair offers, i.e. five €-, four €, and three €-trials, and unfair offers, i.e. two €-, one €-, and zero €-trials, were presented on the right side of the diagram.

b. Treatment of opponents in the dictator game.

Concerning the dictator game, we calculated the ratio (expressed in percent) between the number of trials representing a fair treatment of a previously fair player, unfair treatment of a fair player, fair treatment of a computer player, unfair treatment of a computer player, unfair treatment of an unfair player, and fair treatment of an unfair player, respectively, and the total number of trials presented in this part of the experimental paradigm.

** p < 0.01; * p < 0.05. Error bar represents standard deviation.
