Fairness is an important issue in society now. In this study, we use the ultimatum game
paradigm to explore the influence of different emotions and perspectives on college students’ fairness
preferences. Students from a university who sign up for the experiment were randomly assigned to nine
groups. We conduct an experiment with 2 factors (emotion: happy, no arousal, anger and perspective:
as respondents without bystanders, as responders with bystander, and as bystanders). Two-thirds
participants were asked to recall a happy/anger experience, then they should evaluate their current
emotions. Other participants directly evaluated their current emotions. All participants should finish
ultimatum games with different perspectives (as respondents without bystanders, as responders with
bystander, and as bystanders). The results found that if the outcome is unfair, emotions can significantly
affect the fairness of the results and perspective cannot significantly affect the fairness preferences of the
results. However, if the outcome is unfair but the intention is good emotions cannot affect intentions.
That is to say, triggering anger will affect a person's preference for outcome fairness, but does not affect
preference for intentional fairness.
