In this study, the authors have paid attention to people's reactions to others' self-derogative presentation. Study 1 indicated that people have the script that a self-derogative presentation would elicit a denial response, such as "I don't think so," from the receivers. Moreover, it was also suggested that the derogator has the tendency to believe that the receiver's reaction has an effect of either maintaining or enhancing self-evaluation. Study 2 suggested that the Japanese would make self-derogative presentations, not only on the basis of interpersonal motivations, but also on the basis of self-affirmative motivations. The necessity of examining the details of the effects of self-derogation and the receivers' reactions was discussed.
