RESUMEN
Gratitude expressions have received growing attention from scholars, with research emphasizing its many positive effects on expressers, recipients, and witnesses. Although our knowledge of gratitude expressions' benefits is accumulating, our understanding of its limits is less developed. In this article, we ask when employees' expressions of gratitude toward their leaders positively influence witnesses' perceptions of them, and when they do not. Across three studies including two multiwave surveys and an experiment, we find that expressed gratitude strengthens witnesses' perceptions of expressers' prosocial identities, especially when the leader is believed to be deserving of gratitude. Study 1 examines leader competence as an indicator of deservingness in a sample of leaders and employees in a manufacturing context. Studies 2 and 3 use survey and experimental methods to directly establish leader deservingness as a mechanism of the competence moderator and explore warmth as an additional component of employees' deservingness perceptions. All three studies show how gratitude expression ultimately shapes witnesses' tendencies to help expressers and seek feedback from them. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
RESUMEN
In this research, we examine the effects of cannabis use on creativity and evaluations of creativity. Drawing on both the broaden-and-build theory and the affect-as-information model, we propose that cannabis use would facilitate more creativity as well as more favorable evaluations of creativity via cannabis-induced joviality. We tested this prediction in two experiments, wherein participants were randomly assigned to either a cannabis use or cannabis abstinence condition. We find support for our prediction that cannabis use facilitates joviality, which translates to more favorable evaluations of creativity of one's own ideas and others' ideas. However, our prediction that cannabis use facilitates creativity via joviality was not supported. Our findings suggest that cannabis use may positively bias evaluations of creativity but have no impact on creativity. Implications for theory and practice are discussed.
