Abstract: Snyder(1974)developed self-monitoring to interpret the individual differences in self-presentation. He suggested that concerning for the situational appropriateness of their behaviors, and being sensitive to the cues of situations, using them to guide their self-presentation behavior characterize high self-monitors. The review of my paper have suggested that the Snyder’s definition to the high self-monitoring may be faulty. With the analysis of the function and the process of self-presentation, this paper supposed that people must maintain interpersonal harmony and self harmony in order to make a desired impression. In term of the two dimension, theoretically, there are the four kinds of people in the self-presentation process: the high self-monitors not only maintain self harmony but also interpersonal harmony. The other-directed monitors just maintain interpersonal harmony; self-directed monitors only maintain self harmony, the low self-monitoring maintain neither self harmony nor interpersonal harmony

Key words: self-monitoring, self-presentation, self-harmony, interpersonal-harmony
