Social Psychological Face Perception: Why Appearance Matters. (2008, positive): “…in regions that respond to a variety of positively valenced simuli, while anomalous or unattractive faces elicit greater activation in regions that respond to negatively valenced stimuli (Aharon et al., 2001; O’Doherty et al., 2003; Winston et al., 2007; Zhang, Zebrowitz, & Aharon, 2007).”
Brain correlates of aesthetic judgment of beauty (2006, neutral): “Previous studies have investigated effects of attractiveness and preference by presenting faces (Aharon et al., 2001; Kampe et al., 2002; O’Doherty et al., 2003) or works of art (Kawabata and Zeki, 2004; Vartanian and Goel, 2004) and yielded evidence for a role of reward-related subcortical and limb”
The Attractiveness Halo: Why Some Candidates are Perceived More Favorably than Others (2010, background): “Second, neuropsychologists have identified localized regions of the brain that process facial attractiveness, including the medial orbitofrontal cortex, the fusiform face area, the lateral occipital cortex, and the amygdala (O’Doherty et al. 2003; Ishai 2006; Winston et al. 2006).”
The social re-orientation of adolescence: a neuroscience perspective on the process and its relation to psychopathology (2005, background): “We further speculate that dysregulation of the social information processing network in this critical period may contribute to the onset of mood and anxiety disorders during adolescence.”
