Objective To learn whether compensation of self-evaluation exists when individuals engage in social comparison.Method In reading various materials

（Experiment 1:Compared with those who are better

there was a far difference or a slight difference;Compared with those who are poorer

there was a far difference or a slight difference;Experiment 2:when competing with those who are better

having a cooperation with those who are better;when competing with those who are poorer

having a cooperation with those who are poorer）

self-evaluation vocabulary rating scale has been used to test 80 undergraduates’ self-evaluation of learning ability and characteristics.Results In terms of self-evaluation of the characteristics

the score of upward comparision was higher than that of downward comparison;the score of far upward comparision was higher than that of slightly upward comparision;the score of upward competition was higher than that of upward cooperation.The differences were statistically significant （P<0.05）;while in the self-evaluation of the learning ability

the above comparison between the two groups was statistically insignificant.Conclusion There was no difference in the field of self-evaluation

while in the non-related fields

there were differences in the evaluation.Compared with those who were higher achievers

undergraduates’self-evaluation in related fields will be increased so as to get compensation

and the greater the difference

the greater compensation;if the higher achievers were rivals

the compensation was greater than were collaborators.
