简要总结
The purpose of this study is to investigate neural mechanism of healthy humans underlying group decision making and compare it with that of individual decision-making. Using functional neuroimaging technology combining with computational modeling, we examine how the human brain process social information to make a decision within a group, which often guides humans to make a better decision using collective wisdom.

研究组 & 干预措施
neural mechanisms of decision making
Previous studies on how brain manages a value-based decision have been bounded to individual decisions. The current study will extend the understanding of social dimensions by answering four questions.
干预措施: How people learn another's value preference during decision under risk (Other)

干预措施: Neural mechanism of making a group decision under risk that influences on in-group members (Other)
