This study was to test three hypotheses on intergroup discrimination process: (1) that intergroup discrimination might be lessened when the person defines himself as personal identity, and (2) that there are social egocentrism in the group relationship, and (3) that when the person defines himself as social identity, group-norm oriented processing will be done. Four experiments were conducted to test this. Three experiments(experiment 1, 2 and 3) among them employed artificial categories(yellow and pink group but, all subjects were yellow in real), and one experiments(experiment 4) employed natural categories(humanity major vs. science major but, only humanity major students participated). The first hypothesis was supported by the results of Experiment 1, 2, and the second by those of Experiment 3 and the third by those of Experiment 4.
