“…A similar pattern of increased ingroup cooperation in the face of intensified intergroup competition was found in a prisoner's dilemma, another economic decision task measuring cooperation rates (Reimers and Diekhof 2015). Moreover, a recent neuroimaging study has provided first evidence for testosterone's action in the brain in a sample of male soccer fans playing the UG (Reimers, Büchel, and Diekhof 2017). The results indicate dissociable testosterone-brain correlations depending on individual tendency for costly punishment.…”

“…As to the mechanism underlying parochial altruism, testosterone has recently been proposed to play an important role in mediating the effect of testosterone on decision-making in the UG and related economic decision tasks (Diekhof, Wittmer, and Reimers 2014;Reimers, Büchel, and Diekhof 2017;Reimers and Diekhof 2015). One recent study investigated the behavioral effects of endogenous testosterone by accounting for group membership and intergroup competition.…”

“…Further, as our recent neuroimaging study had observed dissociable correlations between testosterone and brain activity depending on the decision strategy regarding costly punishment (Reimers, Büchel, and Diekhof 2017), we further tested whether individual decision strategy influenced the interaction between testosterone and parochialism in the two studies as well.…”

Supplemental Information 2: Study 2 - Political Party Supporters: Rejection Rates Etc

Testosterone plays a key role in shaping human social behavior. Recent findings have linked testosterone to altruistic behavior in economic decision tasks depending on group membership and intergroup competition. The preferential treatment of ingroup members, while aggression and discrimination is directed towards outgroup members, has been referred to as parochial altruism. Here we investigated in two consecutive studies, whether testosterone is associated with parochial altruism depending on individual tendency for costly punishment. In the first study, 61 men performed a single-shot ultimatum game (UG) in a minimal group context, in which they interacted with members of an ingroup and an outgroup. In the second study, 34 men performed a single-shot UG in a more realistic group context, in which they responded to the proposals of supporters of six political parties during the German election year 2017. Political parties varied in their social distance to the participants' favorite party as indicated by an individual ranking, which resulted in one ingroup (rank 1) and five outgroups of varying social distance (rank 6 referred to as the most distant outgroup). Participants also performed a cued recall task, in which they had to decide whether they had already encountered a face during the UG (oldnew decision). In both studies, results showed a parochial pattern with higher rejection rates of outgroup than ingroup offers. Interestingly, higher salivary testosterone was associated with higher rejection rates related to unfair offers by the most distant outgroup, yet only in the group of self-oriented subjects (pro-selfs). Further, only the pro-selfs showed a memory advantage for unfair interaction partners in study 2, especially if those were ingroup members. The present findings suggest that the latent intergroup bias during decision-making, that was particularly visible in pro-selfs, may be related to endogenous testosterone. In line with previous evidence that already indicated a role of testosterone in shaping male parochial altruism in male soccer fans, these data underscore the general yet rather subtle role of testosterone also in other social settings.

“…Furthermore, in healthy young males, administration of T was demonstrated to potentiate threat-related neural functioning, which mediates dominant, competitive, and aggressive behavior [32]. In regards to decision-making processes, T differentially affects the responsiveness of certain brain regions depending on individual behavioral strategies and motives [33].…”
