“…It is only recently that spatial frequency biases in face recognition have been investigated in ASD (e.g., Boeschoten, Kenemans, van Engeland, & Kemner, 2007;Deruelle, Rondan, Gepner, & Tardif, 2004;Deruelle, Rondan, Salle-Collemiche, Bastard-Rosset, & Da Fonséca, 2008;Leonard, Annaz, Karmiloff-Smith, & Johnson, 2011;Vlamings, Jonkmann, van Daalen, van der Gaag, & Kemner, 2010). Different spatial frequencies correspond to varying levels of detail in the visual environment, with low spatial frequencies (LSFs) generally thought to convey information about the global shape and overall contours of visual stimuli, while HSFs carry information about the more detailed features (Goldstein, 2009).…”
