“…Specifically, the review provided support for the notion put forward in EASI theory that emotional expressions across expressive channels influence observers' affective, inferential, and behavioral responses. With regard to affective responses, one robust finding across numerous studies is that expressions of happiness engender positive affective reactions in observers, such as reciprocal feelings of happiness, positive affect, and/or positive impressions of the expresser (e.g., Barsade, 2002;Sy et al, 2005;Van Kleef et al, 2004a;Van Kleef et al, 2009), whereas expressions of anger engender negative affective responses, such as reciprocal feelings of anger, negative affect, and/or negative impressions of the expresser (e.g., Barsade, 2002;Friedman et al, 2004;Kopelman, Rosette, & Thompson, 2006;Lewis, 2000;Sy et al, 2005;Van Kleef et al, 2004a;Van Kleef et al, 2009). Important to note, these effects occurred across different expressive modalities, and no systematic effects of expressive modality were observed.…”
