There is also evidence of cultural variation in this perceptual style, as neurotypical individuals from Western nations are more field-independent than neurotypical individuals from East-Asian nations. The majority of research on perceptual style in those with ASD has been carried out in Western nations therefore it is unclear whether increased field-independence in ASD is a culturally universal phenotype. Here, we assessed perceptual style in children with and without ASD from England and Singapore using the Children’s Embedded Figures Test and the Framed-Line Test. We found increased field-independence in the English participants with ASD only, suggesting that weak central coherence in ASD is not culturally universal.

Spatial Contrast Sensitivity in Adolescents with Autism Spectrum Disorders / Hwan CUI KOH in Journal of Autism and Developmental Disorders, 40-8 (August 2010)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 40-8 (August 2010) . - p.978-987 Titre : Spatial Contrast Sensitivity in Adolescents with Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Hwan CUI KOH, Auteur ; Elizabeth MILNE, Auteur ; Karen R. DOBKINS, Auteur Année de publication : 2010 Article en page(s) : p.978-987 Langues : Anglais (eng) Mots-clés : Autism-spectrum-disorders Spatial-frequency Contrast-sensitivity Visual-acuity Perception Visual-psychophysics Index. décimale : PER Périodiques Résumé : Adolescents with autism spectrum disorders (ASD) and typically developing (TD) controls underwent a rigorous psychophysical assessment that measured contrast sensitivity to seven spatial frequencies (0.5–20 cycles/degree). A contrast sensitivity function (CSF) was then fitted for each participant, from which four measures were obtained: visual acuity, peak spatial frequency, peak contrast sensitivity, and contrast sensitivity at a low spatial frequency. There were no group differences on any of the four CSF measures, indicating no differential spatial frequency processing in ASD. Although it has been suggested that detail-oriented visual perception in individuals with ASD may be a result of differential sensitivities to low versus high spatial frequencies, the current study finds no evidence to support this hypothesis.
