Any individual’s work performance can vary from day to day and even over the course of a single day. Traditional, static models of job performance that focus on modeling between-person differences in job performance can provide only an incomplete picture of work-performance processes. In this article, we explore within-person variability in performance and its association with changing emotional states and attentional resources. First, the notion of performance episodes is introduced as a useful unit for modeling within-person performance across the workday. Second, we explore the emotion–performance link and show that affective states influence work performance by impacting the attentional resources dedicated to the task. Finally, the variability in affective experiences is discussed in terms of core affect and emotion episodes and their unique effect on individuals’ attention and regulatory resources. The results describe a generalized model of work performance that is influenced by co-occurring affective states and fluctuating attentional resources.

任何人的工作表现每天都可能变化，甚至在一整天中都会变化。传统的静态工作绩效模型侧重于人与人之间的工作绩效差异建模，只能提供工作绩效过程的不完整描述。在本文中，我们探讨了人际绩效的变化及其与变化的情绪状态和注意力资源的关系。首先，引入绩效情节的概念，作为在整个工作日内模拟人际绩效的有用单位。其次，我们探索情绪与绩效的联系，并表明情感状态通过影响专注于任务的注意力资源来影响工作绩效。最后，从核心情感和情绪发作及其对个人注意力和调节资源的独特影响方面讨论了情感体验的变异性。结果描述了一个通用的工作绩效模型，该模型受同时发生的情感状态和注意力资源波动的影响。
