“…Psychometric studies have highlighted that those with ASD not only have difficulties in interpersonal skills such as few friendships, little emotional connectedness, empathy and social enjoyment (e.g., Baron-Cohen et al, 2001, Baron-Cohen and Wheelwright, 2003Rogers et al, 2007;Chevallier et al, 2012a;Calder et al, 2012), but also have difficulties in processing their own emotions including poor emotional introspection, clarity, expression and regulation (e.g., Hill et al, 2004;Berthoz and Hill, 2005;Konstantareas and Stewart, 2006;Szatmari et al, 2008;Petrides et al, 2011;Rieffe et al, 2011;Samson et al, 2012). Hedonic abnormalities from sensitive arousal have also been noted (e.g., Baranek et al, 2006;Baron-Cohen et al, 2009). There is increasing interest in determining whether these emotional and hedonic features should be considered core factors underlying the social and communication deficits of ASD with findings from quantitative, behavioural studies being supplemented in recent years by findings of neuroimaging research.…”
