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.
How people learn another's value preference during decision under risk
The aim of this study is to investigate how an agent learns another's value preference when they should make decisions on behalf of another. This experiment consists of 3 parts(i) measuring individual's loss aversion; (ii) feedback based learning of another's value preference; (iii) and decisions on behalf of others.
Neural mechanism of making a group decision under risk that influences on in-group members
how individuals evaluate the risk and the outcome when they should make a single agreement decision in a group that will influence every member's payoff regardless of individuals' decisions. For the first part of the experiment, we will measure the individual level of loss aversion which will be used as the parameter for controlling individual differences.
Neural mechanism of making a group decision that influences on out-group members
Human is decimated with other species by delegation of one responsibility. Although the person who has no-interests with the outcome of decision, they should make a delegated decision. Therefore, this decision has influences on others who are not part of the group. The third party punishment (Juries decision making) is one example of the decision made by a group influencing the out group members.
fMRI
For neuroimaging passes, the expected duration of each of the experimental protocols is about 1h30 for tasks 1 and 2 and about 2h for task 3. The maximum period foreseen for neuroimaging tests is 3 years and will start as soon as possible. Completion of the behavioral tests.
