事前登録研究：自己呈示の内在化に自己呈示は必要か――自己欺瞞による代替説明可能性の検討

抄録

We examined whether people’s trait increases when asked to impress others with that trait. Participants (N=422) reported their extraversion/introversion and social desirability of extraversion and introversion. After 7 to 10 days, we asked them to write a self-introduction that gave either an extraverted or introverted impression, depending on their condition. Their extraversion/introversion was measured before the self-introduction. Results indicated that (1) only extraversion was rated desirable, (2) a trait to be presented increased in both conditions, and (3) there was a greater effect on extraversion, suggesting that internalization of self-presentation occurred even without self-presentation, especially for socially desirable traits.
