Purpose The objectives of this article are to explore the impacts of imaging significant others on individual’s self-evaluation shifts under China culture context, and to investigate the moderating effects of self-esteem as well. Considering that the college students have similar role experiences, 80 sophomore girl students were recruited as participants. This study selected three kinds of significant others — parents, homosexual friend, and opposite sex friend (including boyfriend). Because the relative selves corresponding to different significant others are different, the researchers developed special traits forms about self-evaluation in order to measure the dependent variables. Procedures and methods This study had two experiments, and a recorder was an important equipment. Experiment 1 was single-factor design. The independent variable was significant others, which has three levels (father or mother, a homosexual friend, an opposite sex friend). On the beginning of the experiment, the participants were told to take a test about their imagination. Firstly, they practiced by voice recording about a piece of landscape prose. Then, the participants were asked to imagine one of the significant others vividly. After the imagination, the participants recalled and wrote down what they had imagined. Then, the experimenter asked the participants to fill the self-evaluation traits form to help another research group which was engaged in the investigation on self-image of contemporary college students. Finally, the participants received a detailed debriefing form. Experiment 2 was similar with experiment 1, except that the former need measure self-esteem after the imagination, and it’s significant others were only homosexual friends and boyfriends. Results and conclusions The significance level of statistic tests in this study is ?<0.05. The researchers explored the relative selves evaluation traits of college girls in China, which were differ from those obtained under western culture context. The experiments proved that imagining significant others may influence individual’s self-evaluation dimension, which was self-evaluation shifts. This study didn’t find the moderating effect of self-esteem.
