The present study used questionnaires, situation priming and the third party punishment game paradigm, to explore the influence of the high or low moral justice and information processing methods(rational processing, empirical processing and control group) on the third party punishment under unfair conditions. The results showed that:(1) As the third party, compared to individuals with low moral justice, people with high moral justice individuals reported higher punishment under unfair conditions.(2) For individuals with high moral justice in unfair circumstance, both people using empirical processing and people in control group reported higher punishment than people using rational processing. While for individuals with high moral justice in fairness circumstance, people using empirical processing reported higher punishment either than those using rational processing or the control group. This finding suggests that cognitive-experience process and emotional process affect people’s behavior response to unfair events, but it varies with the change of situations or individuals.
