Read Montague audio (AUDIO) Virginia Tech Your browser does not support the audio element. Caption Audio quote of Read Montague, a professor at the Fralin Biomedical Research Institute, describing patients playing the “ultimatum game,” where they had to accept or rejects splits of a $20 stake, proposed by either humans or the computer. When humans were playing each other, “fairness” played a role in the decision-making. For the first time, researchers show the impact of the social context may spring from the dynamic interactions of dopamine and serotonin.
