Abstract
<p>The current study examined whether psychological boundaries influence the previously observed relationship between noctcaelador, psychological attachment to the night sky, and hypomania. Participants included 172 undergraduate students who completed measures of noctcaelador, hypomanic personality, hypomanic episodes, and psychological boundaries. As hypothesized, noctcaelador was positively associated with hypomanic personality, hypomanic episodes, and thin psychological boundaries at the bivariate level. Hierarchical regression analyses indicated that while hypomanic personality initially predicted noctcaelador, this relationship was no longer significant after accounting for psychological boundaries. Thin boundaries independently predicted noctcaelador. Findings suggest that the relationship between noctcaelador and hypomanic tendencies may partly reflect broader psychological organization characterized by more permeable psychological boundaries. Implications for personality functioning, experiential openness, and future research on noctcaelador are discussed.</p>
