People spend considerable time on digital media, and are thus often exposed to expressions of emotion by other people. This exposure can lead their own emotion expressions becoming more similar to those of others, a process we refer to as 'digital emotion contagion'. This article reviews the growing literature on digital emotion contagion. After defining emotion contagion, we suggest that one unique feature of digital emotion contagion is that it is mediated by digital media platforms that are motivated to upregulate user emotions. We then turn to measurement, and consider the challenges of demonstrating that digital emotion contagion has occurred, and how these challenges have been addressed. Finally, we call for a greater focus on understanding when emotion contagion effects are likely to be strong versus weak or nonexistent.

数字情绪传染

人们在数字媒体上花费大量时间，因此经常接触到其他人的情感表达。这种暴露会导致他们自己的情绪表达变得与他人更相似，我们将这一过程称为“数字情绪传染”。本文回顾了越来越多的关于数字情绪传染的文献。在定义情绪传染之后，我们认为数字情绪传染的一个独特特征是它是由有动机上调用户情绪的数字媒体平台介导的。然后我们转向测量，并考虑证明数字情绪传染已经发生的挑战，以及如何解决这些挑战。最后，我们呼吁更加关注情绪传染效应何时可能是强与弱或不存在的理解。
