About

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.

neural mechanisms of decision making

Experimental group

Description:

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.

Treatment:

Other: Neural mechanism of making a group decision under risk that influences on in-group members

Other: How people learn another's value preference during decision under risk

Other: Neural mechanism of making a group decision that influences on out-group members

Other: fMRI
