This study was intended to investigate the effects of gender-stereotypes and self-positivity bias on Korean women's self-construals and in-group and out-group perceptions. The results of explicit questionnaire which we developed to measure perceptions of male and female and self-construals showed that positive gender-stereotypes made effects on self-construals and in-group perception. But the results of IAT showed that even gender-stereotypes and self-positivity bias were automatically activated, self-positivity was prior to gender-stereotypes. The results were discussed in terms of self-consistency, self-protect and self-fulfilling prophecy.
