We provide an integrative review of the empirical literature on leadership and affect (emotion, mood, and affective dispositions), which is first and foremost a literature on leader displays of affect. We conclude that the influence of leader affective displays can be understood through the mediation paths of emotional contagion and cognitive interpretation of affect in combination with the first- and second-stage moderators of these paths. We also conclude that the common yet overly simplistic notion that leader displays of positive affect are more effective than leader displays of negative affect can in important part be attributed to an overreliance on subjective ratings as indicators of leadership effectiveness, whereas behavioral indicators of leadership effectiveness suggest a more contingent view of the effectiveness of positive and negative affective displays. We propose that to bolster and further develop these conclusions, we need (a) more research focusing on moderation in dual-path mediation; (b) development of theory about cognitive interpretations following leader affective displays; and (c) more sophisticated models of the difference amongst different affective states to better capture the complexity of their effects. We also outline how evidence regarding the role of follower affect in response to leadership more generally points to the potential for integration of affective and non-affective models of leadership.

我们提供有关领导力和情感（情感，情绪和情感倾向）的经验文献的综合综述，这首先是关于领导力情感展示的文献。我们得出结论，领导者情感展示的影响可以通过情感传染的调解路径和对影响的认知解释与这些路径的第一阶段和第二阶段主持人相结合来理解。我们还得出结论：领导者正面展示情感要比领导者负面展示更有效，这是一个普遍但过于简单的观念，这在很大程度上可以归因于对主观评分的过度依赖，而后者是领导力有效性的指标，而领导力有效性的行为指标表明对正面和负面情感展示的有效性有更偶然的看法。我们建议，为了支持和进一步发展这些结论，我们需要（a）进行更多研究，重点是双路径调解的节制；（b）在领导者的情感展示之后发展有关认知解释的理论；（c）更复杂的不同情感状态之间差异的模型，以更好地捕捉其效果的复杂性。我们还概述了有关跟随者的作用的证据如何更普遍地指出领导力的情感模型和非情感模型整合的潜力。我们需要（a）对双路径调解的适度性进行更多研究；（b）在领导者的情感展示之后发展有关认知解释的理论；（c）更复杂的不同情感状态之间差异的模型，以更好地捕捉其效果的复杂性。我们还概述了有关跟随者的作用的证据如何更普遍地指出领导力的情感模型和非情感模型整合的潜力。我们需要（a）对双路径调解的适度性进行更多研究；（b）在领导者的情感展示之后发展有关认知解释的理论；（c）更复杂的不同情感状态之间差异的模型，以更好地捕捉其效果的复杂性。我们还概述了有关跟随者的作用的证据如何更普遍地指出领导力的情感模型和非情感模型整合的潜力。
