The Neural Basis of Economic
Decision-making in the Ultimatum
Game Jonathan D. Cohen lab, Princeton University

Questions What are the neural correlates of
fairness? What are the relative contributions of
cognitive and emotional processes to economic
decision-making? Hypothesis Decisions to
either accept or reject unfair offers
will engage neural structures involved
in both emotional and cognitive processing

Conclusion Emotional states are an important
factor informing human
decision-making. Competition and interplay
between the anterior insula and the DLPFC
represent the twin demands of the
Ultimatum Game
The
emotional resistance to unfairness The
cognitive task of accumulating money
