Abstract: There are two paradigms about research of justice judgment. One is relational-cognitive model,in which justice judgment is thought to be caused by moral reasoning.The other is subjective-emotional model in that it emphasizes the importance of emotional influence.But there are few empirical studies to resolve the distube between rationalist and intuitionist model.Based on the reseach of emotion and cognition and uncertainty management theory,this study focused on the issue of how people form justic judgments and under what conditions emotion as information may serve a valuable role with 2 experiments. Experiment 1 explored the effect of emotion on judgment of outcome justice.200 students from two universities participated in the experiment and were randomly assigned to one of the conditions of the 2(emotional state: pleasant vs angry) ×4(outcome of other participant:unknown vs. equal vs. worse vs.better)factoral design.The design was balanced with an equal number of participants taking part in each of the eight conditions. Experiment 2 analysized the role of emotion on judgment of procedural justice.120 students from two universities were randomly assigned to one of the conditions of the 2(emotional state: pleasant vs angry) ×3(procedure:no-voice information vs. explicit no voice vs. voice)factorial design. These two experiments found uncertainty mediated the relationship between emotion and justice judgments. Under the conditions of information uncertainty, emotion acted as information. Individuals with positive emotion easily tended to make just decisions. And individuals with negative emotion inclined to unjust judgments. But under certainty conditions, the effect of emotion was not significant. Justice judgments relied on cognition.

摘要： 本研究以不确定管理模型为理论来源，采用实验法探讨了公正判断中的情绪效应。实验1采用2（两种情绪状态：愉快/愤怒）×4（四种结果：比自己多/一样多/比自己少/不知道）被试间设计。实验2采用2（两种情绪状态：愉快/愤怒）×3（三种程序：有发言权/外显无发言权/无发言权信息）被试间设计。分别考察了分配公正与程序公正判断中的情绪影响。结果发现：不确定性调节了情绪与公平判断之间的关系。当用于公平判断的外部信息不明确时，情绪充当了公平判断的线索。
