Objective      To investigate the effects of online violent games on implicit aggressiveness of college students exposed to different real-life violence.  Methods      A total of 373 undergraduates were recruited and tested with reallife violence exposure questionnaire to reveal the current situation of violence exposure. Among them

66 undergraduates were chosen for implicit association test to further investigate the impact of violent games on their implicit aggressiveness.  Results      ①Differences in implicit aggressiveness was not significant in different genders(P0.05). ②The violent type of games significantly affected implicit aggressiveness(P0.05). ③The priming effect of violence exposure on implicit aggressiveness was obvious

showing a significantly higher score of implicit aggressiveness in students with highviolence and lowviolence exposure(P0.05). ④The 2 impact factors

types of games and levels (high or low) of violence exposure

on implicit aggressiveness were significantly interacted. The college students exposed to lowviolence in real life were easier to be affected by online violent games

and their implicit aggressiveness significantly increased(P0.05).     Conclusion     Our study demonstrates that online violent games significantly increase implicit aggressiveness of college student with low-violence exposure in real-life.
