“…The observational focus on affect as either positive (eight studies), negative (four studies), or both (nine studies) was identified. Four studies (Barsade, 2002; Bartel & Saavedra, 2000; Costa et al, 2017; Lehmann-Willenbrock et al, 2011) were grounded in a circumplex affect model (e.g., Larsen & Diener, 1992; Russell, 1980), which conceptualizes affect on two dimensions of valence on a negative-positive scale, and level of activation. The focus on affective valence rather than discrete emotions is consistent with emotion measure reviews (e.g., Mauss & Robinson, 2009) which have suggested that a dimensional perspective (valence; arousal) may be more suitable for measuring group behavioral data, capturing broad affect phenomena (i.e., mood, climate).…”
