Numerous studies have focused on the effect of motivation on performance in the workplace. The purpose of this paper is to evaluate the somewhat overlooked role of positive and negative emotions as potential mediators of this critical association.,The longitudinal study employed multilevel modeling for assessing the effects of motivation, emotions and work satisfaction on job performance. In total, 116 respondents provided 1,044 responses at nine consecutive measurement points.,Findings indicated that positive emotions and job satisfaction mediate the positive association between autonomous motivation and performance. Concurrently, negative emotions and decreased job satisfaction mediated the negative associations between controlled motivation and job performance.,The results address only the within-subject and between-subject analysis of temporal variations in emotions and behavior. Future studies can include higher levels of analysis, such as group, team and organizational contexts.,This research contributes to self-determination theory by highlighting the role of emotions in understanding how motivation shapes workplace performance.

员工的动力，情绪和绩效：纵向日记研究

许多研究集中于动机对工作场所绩效的影响。本文的目的是评估正向情绪和负向情绪作为这种关键联想的潜在中介者所起的被忽视的作用。纵向研究采用多层次模型来评估动机，情绪和工作满意度对工作绩效的影响。总共有116位受访者在9个连续的测量点上提供了1,044个响应。研究表明，积极的情绪和工作满意度可以调节自主动机与绩效之间的积极联系。同时，负面情绪和工作满意度下降介导了受控动机与工作绩效之间的负相关关系。结果仅涉及对象内和对象间对情绪和行为的时间变化的分析。未来的研究可能包括更高层次的分析，例如团队，团队和组织环境。这项研究通过强调情绪在理解动机如何影响工作场所绩效中的作用，为自决理论做出了贡献。
