Abstract

This study examined the mediating role of personality traits on the relationship between executive functioning (EF) domains and dimensions of identity development. A cross-sectional, correlational design was utilized. 364 participants (MAge = 20.03, SD = 4.11) completed self-report measures of EF, personality, and identity. It was hypothesized that the Big 5 personality traits would mediate associations between EF components (working memory, inhibitory control, and cognitive flexibility) and adaptive or maladaptive identity dimensions. Results indicated that conscientiousness partially mediated the relationship between working memory and identification with commitment, while fully mediating the relationship between working memory and commitment making, suggesting that self-monitoring personality traits facilitate adaptive identity development. Neuroticism was found to fully mediate the relationship between inhibitory control and ruminative exploration, while partially mediating its relationship with identity distress. In contrast, no support was found for models involving openness, extraversion, or agreeableness. Cognitive flexibility was not found to be significantly associated with identity exploration. These findings suggest that personality traits, particularly conscientiousness and neuroticism, play a critical role in shaping how EF contributes to identity development. Overall, the results provide a more integrated understanding of the cognitive and behavioral mechanisms underlying identity formation, which may inform interventions aimed at promoting adaptive identity development.
