Substantial Heritability Underlies Fairness Norm Adaptation Capability and its Neural Basis.

ABSTRACT: The present research uncovers the shared genetic underpinnings of fairness norm adaptation capability, its neural correlates, and long-term mental health outcomes. One hundred and eighty-six twins are recruited and played as responders in the Ultimatum Game (UG) while undergoing fMRI scanning in their early adulthood (Study-1) and are measured on depressive symptoms eight years later (Study-2). With computational modeling, the process of norm adaptation is differentiated from that of fairness valuation in UG. The two processes both have moderate levels of heritability. The anterior insula has a significant phenotypic correlation, whereas the Supplementary Motor Area/Medial Frontal Gyrus (SMA/mSFG) shows both a significant phenotypic correlation and a shared genetic influence with the learn
