Cognitive science research related to the brain have begun to analyze and explore through brain waves ways to find out people in decision-making or thinking different types of problems, changes in the brain region or EEG frequency. Kahnema and Trersky put forward prospect theory in 1979, from the perspective of cognitive psychology, corresponds to expected utility theory in game theory. Prospect theory used nonlinear utility function or value function to explain the psychological and behavioral of decision makers in decision-making process. This theory suggests that individual positions based on different reference points have different risk attitudes. Many studies have shown that many human psychological behavior can use physiological signals to detect. Such as heart rate, brain waves and other signals. And now has proved that human cerebral cortex in mood, behavior and experience, etc., play an important role, such as the prefrontal cortex functional asymmetry zones are related to different emotions behavior. But pending explore whether the same effect on the risk chase or on the risk averse. Therefore, this study will attempt to use EEG to study the decision-makers''s brain activity characteristics in the preferences selected, respectively in risk aversion or in risk chase. Through this research to help decision makers determine its reference point in different decision rules settings.
