“…The behaviours themselves -which range from a fear of hairdryers to a fascination with twinkling lightshave been shown to occur in a large proportion of autistic 1 individuals, across sensory modalities (Ben-Sasson et al, 2009) and across ages (Crane et al, 2009), intellectual abilities and autism severity (Ben-Sasson et al, 2009;Crane et al, 2009;Hochhauser & Engel-Yeger, 2010). Empirical links between sensory atypicalities and behavioural difficulties (Baker, Lane, Angley, & Young, 2008;O'Donnell, Deitz, Kartin, Nalty, & Dawson, 2012), academic achievement (Ashburner, Ziviani, & Rodger, 2008) and anxiety and depression (Green, Ben-Sasson, Soto, & Carter, 2012;Mazurek et al, 2012) point to the often-debilitating impact that sensory difficulties can have on individuals' daily lives.…”
