... Furthermore, previous work focusing on repeated one-shot games, suggested that unfairness arising from the discrepancy between self-other reward amounts in the UG engages autonomic arousal systems in humans (for example, cardiac response or skin conductance), also predicting participants' accept versus reject decisions 33,34 . Nevertheless, the role of pupil-linked central arousal systems during social interactive decision-making remains mostly unknown apart from one study conducted in a limited number of children (N = 15) which suggested that pupil dilation in response to viewing faces indexes familiarity with the face 35 . Considering that our UG task was specifically tailored to allow participants to experience an evolving interpersonal negotiation environment, we asked healthy volunteers (N = 44) to perform the novel experimental task while undergoing pupillometry and explored the role of pupil-linked central arousal systems in social interactive decision-making. ...
