Most of studies on self-presentation have measured individual difference of self-presentation with questionnaires. However, the resent research on implicit attitude suggests that self-presentational factor affects the responses in a questionnaire. There is a possibility that self- presentational factor influences on measuring individual difference of self- presentation with questionnaires. The purpose of this study was to clarify the validity of Snyder (1974)'s self-monitoring scale, which was one of measures of self-presentation. Experiment 1 examined the relationship between self-monitoring scale and the difference of Rosenberg (1965)'s Self- Esteem scores in high and low anonymity conditions, and found no correlation between these variables. In order to clarify why participants changed Self-Esteem scores, experiment 2 explored the effect of anonymity on explicit and implicit Self-Esteem. This study used Rosenberg's Self- Esteem scale as an explicit measure and the name letter effect as an implicit measure. Experiment 2 found that the operation of anonymity influenced on explicit Self-Esteem but not on implicit Self-Esteem. These findings suggest that self-monitoring scale did not predict individual difference of self-presentational behavior. There is a possiblity that self- monitoring scale has low validity as a measure of self-presentation. But, in this study, the correlation between explicit and implicit Self-Esteem was not higher in high anonymity condition than low anonymity condition. It also cast a doubt on the validity of name letter effect as an implicit measure of Self-Esteem. Further research is needed to confirm the effect of anonymity.
