A casual role for right temporoparietal junction in random pairing repeated holdup game by Wang Xiaoqin, Su Hao, Liu Qin, Pan Jiali, and Zhang Xiaomin

Abstract: Holdup problem is a common problem in specific investment transactions of noncontractible relationship, which is affected by human trust behavior, cooperation behavior and altruistic behavior. Recent neurological studies have shown that the right temporoparietal junction (rTPJ) plays an important role in social cognition and prosocial decision making. The aim of this study is to modulate the excitability of brain regions rTPJ by transcranial direct current stimulation and to explore the effects of rTPJ on participants’ offer and the minimum willingness to accept (MWTA) behaviors in the random pairing repeated holdup game. Our results showed that compared with sham stimulation, cathodal stimulation significantly increased the offer and anodal stimulation significantly decreased the MWTA of participants. One possible explanation is that the inhibition of the rTPJ makes it harder for participants to distinguish between their own benefits and those of others, and participants may rely on simple equality rules to solve this problem, resulting in higher offer. The activation of the rTPJ improves the participants’ perspective-taking, allowing the participants to change their strategy through the perspective of others, thus reducing the loss of investment by lowering the MWTA.
