“…Several variables are known to affect the precision in facial emotion recognition: It is known, for instance, that subjects suffering from schizophrenia, autism, or Alzheimer’s disease frequently exhibit difficulties in recognizing emotional expressions (e.g., Baron-Cohen, Wheelwright, Hill, Raste, & Plumb, 2001; Edwards, Pattison, Jackson, & Wales, 2001; Hargrave, Maddock, & Stone, 2002; Harms, Martin, & Wallace, 2010; Tsoi et al, 2008; Weiss et al, 2008). Other influences on the ability to recognize emotions in faces have been shown, for example, for age (Isaacowitz et al, 2007), gender of the observer or the presented face (McClure, 2000; Pixton, 2011), affective content (Becker & Detweiler-Bedell, 2009; Calvo & Marrero, 2009), saliency of specific facial features (Calvo & Nummenmaa, 2008), or prior attention (Gómez-Cuerva & Raymond, 2011).…”
