Abstract

Cultivated through the ages, the pursuit of psychological well-being (PWB) has long intrigued humanity, with prior research often examining its correlation with income. Nonetheless, predicting happiness based solely on income remains a challenge. Recent studies have highlighted personality traits as crucial moderators, exhibiting significant regulatory effects. This study seeks to explore how personality traits modulate the impact of individual income on PWB. Going beyond traditional personality trait scores, neural activity offers a multidimensional perspective on personality traits. Therefore, we utilize functional connectivity as variables reflecting personality traits in moderation analyses. Leveraging large-scale resting-state functional magnetic resonance imaging data, our findings underscore the pivotal moderating role of personality trait-related functional connectivity. Specifically, connections associated with the cerebellum, particularly those involving the cerebellum's neural activity, play a crucial role. This research enriches our comprehension of the relationship between income and well-being and delves into the neural mechanisms underlying the moderating influence of personality traits.
