Abstract:Decision making is a process of making choices to situations and determining strategies by using cognitive abilities such as perception, memory and thinking. Electroencephalogram(EEG) technology and EEG information analysis is one of the important methods to study and analyze brain decision function and decision mechanism. The two-person dilemma game has a wide range of applications and prospects in the fields of traditional humanities and contemporary engineering and medicine. The prisoner’s dilemma game and the chicken game are two classic game models in the study of two-person dilemma. The EEG information analysis of these two kinds of two-person dilemma games can not only objectively describe the dynamic information processing of the brain in the game choice strategy, but also reveal the brain mechanism of cooperation in the game. This review summarizes the experimental paradigms, decision-making strategies and the findings of brain signal detection in recent years of these two kinds of twoperson dilemma games. Finally, the research trend and direction of two-person dilemma games are discussed.
