Abstract: Self-uncertainty refers to the feeling of doubt from individual’s inner, and refers to the implicit subjective feelings and explicit reactions which are produced by the sense of doubt and instability about oneself. Self-reporting and scenarios manipulation are 2 main research methods of self-uncertainty. Since De Cremer and Sedikides’ empirical study proved that self-uncertainty can moderate the procedural justice effect, researchers have been developing this field by decomposing the self-uncertainty into the uncertainty emotion about self uncertainty, standing uncertainty and belongingness uncertainty, and by discussing the procedural justice cognitive mechanism. Further researches can also develop this field by investigating the self-uncertainty moderating effect in the Chinese background, by analyzing the interaction between self-uncertainty trait and state, and by researching the combination of self-uncertainty and other related variables, such as self-affirmation, newcomers and information uncertainty.

Key words: self-uncertainty, procedural justice effect, moderating effect
