In this study, we constructed a psychological explanation model of personal epidemic concealment, which included deceptive traits, situational drives and the fluke mind. Two experimental situations, positive reinforcement (a game of money reward, selfish-with-harming-others situation) and negative reinforcement (a game of points clearance, selfish-without-harming-others situation)，were designed to examine people’s behavior of concealing their real travels in the epidemic outbreak. In addition, considering the level of monetary incentives might impact on the deception behavior, we set up two high and low money reward games together with the points clearance game. So there were three experimental processes, which were within-subject design. In addition，we also designed three types of disclosure objects (between-subjects design): self-disclosure, families and neighborhoods revelation, and used E-prime to write the experimental program.
