This study examined whether (1) perceived social desirability (PSD) and personal desirability (PD) of each Big Five trait are positively correlated, and (2) perceived relational mobility (PRM) moderates its strength. Participants (Study 1: 224 undergraduate students; Study 2: 558 research firm monitors) reported PSD and PD of the Big Five scale items and PRM. Confirmatory factor analyses revealed that a five-factor structure with a random slope or a method factor fit best for both PSD and PD. Correlations between PSD and PD were positive for all traits (Study 1: rs = .52–.69; Study 2: rs = .59–.67), and their strength differed by high vs. low PRM for some traits: conscientiousness (r = .42 vs. .64 in Study 1 and r = .55 vs. .66 in Study 2) and agreeableness (r = .59 vs. .73 in Study 2). Implications for studies of personality trait desirability were discussed.

This study examined whether high self-deceivers form their overly positive perception of their traits through overestimating their performance of self-presentation where they need to impress others as being extraverted/introverted, exhibiting more internalization of self-presentation (IOSP) of the trait. Participants were instructed to give either an extraverted or introverted impression through an oral (Study 1, N = 39) or written (Study 2, N = 62) self-presentation. Participants reported dispositional self-deception, self-presentation efficacy, and extraversion before and after self-presentation. Independent raters provided other-reported extraversion by examining the self-presentation. Across the two studies, two-way mixed ANOVA revealed that predicted change in extraversion occurred only for participants who made extraverted self-presentation. With the change in extraversion as an index of IOSP, mediation analyses revealed indirect effects of dispositional self-deception on IOSP via self-presentation efficacy but not other-reported extraversion. These results suggested that (a) people only internalize socially desirable traits like extraversion but not introversion, (b) writing to others is sufficient to cause IOSP, and (c) high self-deceivers internalize extraverted self-presentation not through actual performance but its subjective evaluation.

外向性および内向性の自己呈示が呈示者の顕在的・潜在的外向性に与える影響 Reviewed Open Access

The Japanese Journal of Personality Vol. 32 ( 2 ) page： 57 - 68 2023.7

Language：Japanese Publishing type：Research paper (scientific journal) Publisher：Japan Society of Personality Psychology

This study examined whether (1) self-presentation of extraversion/introversion changes the presenter’s explicit and implicit extraversion and (2) the presence of an audience informed of the presenter’s personal information moderates the effects. Sixty-two participants were randomly assigned to four conditions: 2 (trait presented: extraversion or introversion)×2 (situation: presence or absence of audience). We conducted three-way ANOVA where the timing of measurement (immediately before or after self-presentation) served as a within-subject factor, separately for explicit and implicit extraversion as a dependent variable. Throughout the analyses, only the main effect of the timing for implicit extraversion was significant; self-presentation increased implicit but not explicit extraversion, irrespective of the trait presented or the situation. We discussed mechanisms underlying change in implicit extraversion and reasons for discrepancy from previous findings, especially the possibility that measurement immediately before self-presentation may have inhibited change in explicit extraversion.

Registered Report: Does Internalization of Self-Presentation Require Self-Presentation? An Examination of Alternative Explanation by Self-Deception Reviewed Open Access

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.
