Authenticity as a pathway to neutral acceptance of death
Neutral acceptance, the view that death is an integral part of life, is distinct from the mere absence of death anxiety, yet its psychological antecedents remain poorly understood. Drawing on an existential perspective, we propose that authenticity fosters neutral acceptance by alleviating existential guilt over a life not fully lived. Across three studies, we found converging evidence for this proposition. Study 1 (N = 489) documented a cross-se…
Essentializing Happiness Mitigates the Changes in Subjective Well-Being Following Negative Life Events
People hold different beliefs about the changeability of happiness. Some believe that happiness is biologically predetermined and thus unchangeable (essentialist beliefs), while others believe that it is malleable and can be changed (non-essentialist beliefs). Do these beliefs have a tangible impact on how individuals actually experience well-being? Here, we predict and empirically demonstrate that endorsing essentialist beliefs about happiness (…
Reactive stress tolerance and reaction speed in the adaptive determination test as predictors of cadets' combat training performance
Military training increasingly requires rapid and accurate decisions under high cognitive load, making executive functions and performance stability under stress operationally relevant. This study examined whether indices derived from the adaptive Determination Test (DT) − reactive stress tolerance (RST), median reaction time (MRT), and incorrect reactions (IR) − are associated with cadets' combat training performance. Ninety-one cadets (71 men, …
Death as a Way Out
Extensive research documents the far-reaching consequences of social class, yet one fundamental question remains underexplored: Does social class shape how people construe death? We examine whether subjective social class is associated with distinct death attitudes and whether those attitudes, in turn, are related to suicidal ideation. Across Studies 1a and 1b, lower subjective social class was associated with greater escape acceptance, which inv…
Mitigating the Negative Effects of Lower-Class Backgrounds on Subjective Well-Being
Why Do Happy People Exercise More? The Role of Beliefs in the Psychosocial Benefits of Exercise
Recent studies indicate a robust relationship between subjective well-being (SWB) and exercise behavior. Past research has successfully uncovered various mechanisms through which exercise boosts SWB. However, little is known about how SWB influences exercise. The present research proposes that SWB affects individuals’ beliefs about exercise benefits, which in turn impact their exercise behavior. In particular, we hypothesize that happier individu…
Gender-atypical male military leaders enhance followers’ training performance
Proactive coping mediates the relationship between the narcissism phenotypes and psychological health
Although the relationship between grandiose and vulnerable narcissism and psychological health is widely accepted, little is known about whether and how coping strategies explain this relationship. We examined the mediating role of proactive coping in this relationship, with a sample of 280 participants from five colleges in Korea. We used four parallel multiple mediation models, and controlled for the indirect effects of coping flexibility, self…
