“…Examples of the processes of affect convergence include emotional contagion (e.g., Hatfield, Rapson, & Cacioppo, 1994), behavioural entrainment (Kelly, 1988), empathy (De Vignemont & Singer, 2006), attractionselection-attrition (Schneider, 1987;George, 1990), socialisation to group affective norms (Morrison, 1993), as well as exposure to common affective events (Westman, 2002). These processes generally encourage the development of a consistent group affective tone (for a full review see Collins, Lawrence, Troth, & Jordan, 2013). Studies on affective convergence at the dyadic level suggest that these processes of convergence are quite robust (e.g., Laird et al, 1994;SonnbyBorgström, Jönsson, & Svensson, 2008) and can occur immediately and automatically (Hess & Blairy, 2001).…”
