Abstract

People sharing similar characteristics are likely to be connected in social networks. The purpose of this study is to theoretically integrate homophily in social networks with neuroscience so that we can better understand complex human nature. In this study, homophily of older adults based on the amygdala volume was tested. Korean Social Health and Aging Project (KSHAP) data were analyzed to examine the hypothesis. Between 71 participants (43 of them female), 75 dyadic relationships were identified. The results show that two connected older adults' amygdala volumes were marginally correlated (p = 0.06). The tendency is clearer for those who meet each other every day (p = 0.004) or those who talk to each other every day (p = 0.008). No signiffcant association between two people's amygdala was found when they did not interact so frequently. The results imply that homophily occurs based on neurological features, especially the amygdala volume.
