Ueda and Yamagata (2023) demonstrated that when participants were asked to recall personal episodes for writing self-introductions aimed at giving either an extraverted or an introverted impression to others, their levels of extraversion or introversion changed in accordance with their self-presentation. This study explored whether traits not targeted for impressing others (i.e., the Big Five personality traits other than extraversion) also changed. A secondary analysis of their data (N = 422) revealed that in the extraversion condition, all traits exhibited changes toward more socially desirable directions, whereas in the introversion condition, only agreeableness and conscientiousness did so. The magnitude of change across the traits was correlated, suggesting the existence of a shared mechanism. These results suggest that recalling episodes for self-presentation may lead to broader personality changes, including in traits not explicitly targeted. We proposed several mechanisms that could explain the observed changes.
