Abstract: In recent years, campus violence has been a focus of academic research, but deep exploration of the logic of the students' behavior in conflicts is scarce. This paper, based on framing effect, analyzes the reasons why students take risks. The study finds that, in the context of campus conflict, the role and gender in the event have an interactive impact on the students' risk preference. Participants tend to be more adventurous than onlookers, and boys show opposite risk decisions due to differences in information properties, while girls always show a higher risk tendency in the situation. By exploring and analyzing the students' possible behavior preferences, we can optimize the way of campus safety education, which is conducive to increasing the effectiveness of campus risk communication.

Key words: participant, bystander, risk appetite, framing effect
