Emotion differentiation captures the detail with which people describe their emotional experiences. A compelling body of research has linked low and negative emotion differentiation to a host of adverse psychological outcomes, yet conceptual and methodological questions and issues remain. We think that the time is right to review and reflect on this growing literature to gain clarity that can be applied to future research. We first review assessment of emotion differentiation while highlighting the methodological variation across studies. Then supported by the literature review, we discuss disconnections between the conceptualization and measurement of differentiation. Finally, to motivate future research, we propose factors that we hypothesize are associated with potentially beneficial effects of emotion differentiation in a given situation (i.e., related to state emotion differentiation) and more generally across time (i.e., related to trait emotion differentiation).

明确区分情绪

情感差异捕捉了人们描述自己的情感经历的细节。引人注目的研究机构将情绪低下和消极的分化与许多不良的心理结果联系在一起，但是概念和方法上的问题仍然存在。我们认为现在是时候来回顾和反思这一成长中的文献，以获取可用于将来研究的清晰性。我们首先回顾一下情绪差异的评估，同时重点介绍跨研究的方法差异。然后，在文献综述的支持下，我们讨论概念化和差异度量之间的脱节。最后，为了激励未来的研究，我们提出了我们假设的因素与给定情况下情绪分化的潜在有益影响相关联（即，
