“…Research on emotional contagion in CMC found that emotional face-to-face communications and CMC are very similar, and, probably the only difference is that there are more frequent and explicit emotion expressions in CMC than face-to-face communications (Derks, Fischer, & Bos, 2008). For example, in social media contexts, when consumers are exposed to positive messages, emotional contagion can take place and lead them to experience the same positive emotions (Chen, Kim, & Lin, 2015;Kramer, Guillory, & Hancock, 2014). Besides, previous research has shown that, in CMC, emotionally-charged messages (e.g., using emotional words) can trigger more cognitive involvement (e.g., attention) (Bayer, Sommer, & Schacht, 2012;Kissler, Herbert, Peyk, & Junghofer, 2007;Smith & Petty, 1996) and higher psychological arousal (Berger, 2011;Berger & Milkman, 2012), which, in turn, can impact the message receivers' feedback and reciprocity Huffaker, 2010;, participation , and social sharing behavior (Heath, 1996;Luminet IV, Bouts, Delie, Manstead, & Rimé , 2000;Peters, Kashima, & Clark, 2009;Rimé , 2009;Kim & Johnson, 2016).…”
