Social and Economic Decision-Making Utility Based on EEG Signals Analysis in Women

Introduction: One of the new fields of study is Neuroeconomics which investigates the effect of human brain on economic decision makings. In the current study, economic decision making was examined, using the Prisoner’s Dilemma Game among females followed by electroencephalogram (EEG) analysis. Materials and Methods: Female participants were chosen based on their ability of making rational decision examined in Prisoner’s Dilemma Game for each group. Based on the data obtained from the Prisoner’s Dilemma Game, two groups existed: one includes female with good decision making in economic field in Prisoner’s Dilemma Test and group 2 consists of females who did not chose appropriate economic decision during the game. Also EEG analysis was performed at the end of EEG recording, participates were asked if they feel utility about their economic decision making in their entire life or not. Results: The current results showed that the Economic Decision-Making Utility was more in group with better economic decision in Prisoner’s Dilemma Game. EEG analysis shows that Alpha/Beta ratio is %16.5 and Theta/Beta ratio is %12.5 less in group 2 who stayed silent and did not betray other suspect (***P<0.001). Conclusion: According to the current data, utility about economic decisions may affect decision-making and EEG or vice versa, as Alpha/Beta and Theta/Beta ratio are less in the group who stayed silent and did not betray other suspect.
