Abstract
En 中文
Positive affect is a fundamental component of well-being, influencing multiple domains of psychological and physical functioning. This article synthesizes empirical research on positive affect dynamics in naturalistic contexts, emphasizing their associations with mental- and physical-health outcomes. Although a substantial amount of research has investigated positive emotional experiences through trait-based and state-based measurement paradigms, recent methodological innovations highlight the temporal dynamics of affective experiences within individuals across multiple timescales. Here, we examine how key temporal properties-including variability, instability, inertia, and reactivity-relate to adaptive functioning and health-relevant outcomes. These dynamic approaches extend traditional assessment frameworks, offering greater predictive utility for understanding health trajectories beyond static measures. Despite these advances, significant challenges remain in measuring, modeling, and integrating affective processes across diverse temporal resolutions and contexts. Addressing these issues requires refined methodological approaches that enhance precision and interpretability. We conclude by outlining a forward-looking agenda for advancing positive affect dynamics research, emphasizing its potential applications for promoting health and resilience.
