Abstract: Video games are so widely popular that have attracted lots of researchers' attention for a long time. Video games have great impacts on players of all ages. According to the General Learning Model(GLM),the effects of video games depend on the content of the game. The violent video games can stimulate players' aggressive cognition,offensive emotion and behavior,while the prosocial video games can improve the player' prosocial cognition,emotion and behavior. Previous studies mainly inspected the effects of video games on players' prosocial or antisocial knowledge,empathy,and aggressive behavioral tendencies. In recent two years,the researchers also found that video games could affect the players' humanization. But they all employed subjective reports which have always been questioned for their validity. Meanwhile no researchers have studied that the effects prosocial video games played on players' humanization. So in present study,we inspected the impact of prosocial video games had on players' humanization to themselves and to others through two experiments in explicit and implicit levels respectively in order to get a comprehensive understanding. The main results were as follows:In explicit level,compared to neutral game,in the dimension of Human Nature and Human Uniqueness,prosocial video games could significantly improve the players' perceived humanity to themselves and to others. In implicit level,compared to neutral game,in the dimension of Human Uniqueness,playing prosocial video games could not only significantly improve the degree of self-perception bias,but also improve the degree of others perception bias; However in the dimension of Human Nature,playing prosocial video games could only significantly improve the degree of payers' self-perception bias but had no effect on others-perception bias. These results suggest prosocial video games have important effects on players' Humanization to themselves and to others.
