Reciprocity in mutual rule-observance. obs, the number of cases that the opponent mouse observed the rule during the partner’s reward delivery in the current round. vio, the number of cases that the opponent mouse disrupted the partner’s reward in the current round. obs*(or vio*), the number of cases that the opponent mouse showed rule-observance (or rule-violation) behavior in the previous round. obs**, The number of cases that the mouse performed positive reciprocity in the previous round. a Rule-violation of a mouse after the other’s rule-violation in the previous round was defined as negative reciprocity. Probability of negative reciprocity decreased (i.e., tolerance increased) in MObs (One-way RM ANOVA, quarter, F3, 45 = 12.8, P < 0.001) but not in MVio. b Rule-observance of a mouse after the other’s rule-observance in the previous round was defined as positive reciprocity. Probability of positive reciprocity increased in MObs (one-way RM ANOVA, quarter, F3, 45 = 19.8, P < 0.001) but not in MVio. c Rule-observance of a mouse after it already showed positive reciprocity in the previous round is defined as persistent rule-observance. Probability of persistent rule-observance at multiple unrewarded trials (i.e., partner rewarded.) was increased in both groups, but the level of MVio remained lower than that of MObs (two-way RM ANOVA, F1,24 = 252.30, P < 0.0001)
