“…Two studies have measured perceptual discrimination of facial identity and emotion for "low" and "high" spatial frequency faces, and showed that while TD individuals rely more on low, than high, spatial frequencies, individuals with ASD exhibit the reverse pattern (Deruelle, Rondan, Gepner, & Tardif, 2004;Deruelle, Rondan, Salle-Collemiche, Bastard-Rosset, & Da Fonseca, 2008, and see Boeschoten, Kenemans, van Engeland, & Kemner, 2007b for similar and relevant results obtained from EEG studies). In line with these findings, another study showed Spatial Autism 22 that while individuals with ASD have no trouble discriminating facial emotions in unfiltered faces, they underperform TD individuals when the faces contain only low spatial frequencies (Katsyri, Saalasti, Tiippana, von Wendt, & Sams, 2008).…”
