Based on the Conservation of Resources theory, we develop dual mechanisms by which lunchtime recovery activities predict creativity. Specifically, by conceptualizing the quality of lunchtime naps and meals as examples of recovery activities, we expect these recovery activities help individuals replenish their psychological resources in the form of more work engagement (affective process) and less cognitive depletion (cognitive process). Further, individuals are expected to utilize these available psychological resources to generate creative ideas. To test our model, we used a group-mean centering approach to focus on within-person effects by recruiting 230 employees working at construction sites in South Korea. Overall, after removing 242 invalid observations (omitting at least two items and not reporting the duration of a nap), we finalized a total of two-wave 1598 daily questionnaires. A high quality of lunchtime naps and meals helps individuals recover their emotional resources (more work engagement) and cognitive resources (less cognitive depletion), which predict individuals' creativity. Finally, although indirect effects of the two recovery activities on creativity via affective and cognitive processes were generally supported, the indirect effect of lunch nap quality on creativity via work engagement was not significant, suggesting most of the effect is due to meal quality rather than nap quality.
基于资源保存理论，我们提出了两种机制，即午休恢复活动可以预测创造力。具体来说，通过将午休小睡和用餐质量概念化为恢复活动的例子，我们期望这些恢复活动以更多的工作投入（情感过程）和更少的认知枯竭（认知过程）的形式帮助个人补充心理资源。此外，个人有望利用这些可用的心理资源来产生创意。为了检验我们的模型，我们使用了组均值中心化方法，通过招募在韩国建筑工地工作的 230 名员工，关注个体内效应。总体而言，在剔除 242 个无效观察值（至少遗漏了两个项目并且没有报告小睡时间）后，我们最终完成了总共两波 1598 份每日问卷。高质量的午休小睡和用餐有助于个人恢复情感资源（更多的工作投入）和认知资源（更少的认知枯竭），从而预测个人的创造力。最后，尽管通过情感和认知过程，两种恢复活动对创造力的间接影响总体上得到了支持，但午休小睡质量对创造力的间接影响通过工作投入并不显著，这表明大部分影响是由于用餐质量而不是小睡质量。
