报告题目：The algorithm of dominance: Choice and adaptation within social competitions
报告摘要：Dominant status is an important resource in social species, including our own. It plays a critically role in intraspecific competition, serving to motivate mobility within dominance hierarchy, or maintain the extant hierarchy. Explaining and predicting dominance-related behavior is a goal in many social and biological sciences. To date, research on human dominance has generally focused on cognitive functions such as emotion regulation or response inhibition. However, dominance may also reflect functions and neural circuits related to reward and adaptation — mechanisms critical for survival and thriving. Here combining fMRI, computational modeling, and economic experiments and theories, I show that models adapted from game theory are able to capture the neural processing of reward and social learning within interpersonal competition. Using these algorithms, I then go on to illustrate how individual differences in dominance and social learning are mechanistically connected at both neural and behavioral levels. These results point to a neurobehavioral signature of human dominance, which can be objectively quantified, tested, and ultimately applied as individualized metrics with potential prognostic or predictive utility for social pathologies in psychiatric and developmental disorders.
