“…Important gender differences exist in the production, perception, and regulation of facial expression. Women are more emotionally expressive and more empathic than men (Eisenberg & Lennon, 1983;Kring & Gordon, 1998); more accurate and/or efficient in processing facial expressions of emotion (Hall, 1978;Hall & Matsumoto, 2004;Hoffmann, Kessler, Eppel, Rukavina, & Traue, 2010); show more facial mimicry than men (Dimberg & Lundquist, 1990); and are more susceptible to emotional contagion, as revealed both in self-report and dyadic interaction (Doherty, Orimoto, Singelis, Hatfield, & Hebb, 1995). Gender differences have also been found in the effects of pacifier use during infancy, which arguably blocks facial mimicry, on facial mimicry recorded at age seven.…”
