Eighteen children with predominantly intellectual low-functioning ASD (LFA, IQ <80) and two control groups (mental and chronological age matched), were assessed for their ability to classify emotional faces, of high, medium and low intensities, as happy or angry. For anger, the LFA group made more errors for lower intensity expressions than the control groups, classifications did not differ for happiness. This is the first study to find that the LFA group made more across-valence errors than controls. These data are consistent with atypical facial expression processing in ASD being associated with differences in the structure of emotion categories.

Judging the Intensity of Emotional Expression in Faces: the Effects of Colored Tints on Individuals With Autism Spectrum Disorder / Lydia WHITAKER in Autism Research, 9-4 (April 2016)  

Public ISBD [article]  inAutism Research > 9-4 (April 2016) . - p.450-459 Titre : Judging the Intensity of Emotional Expression in Faces: the Effects of Colored Tints on Individuals With Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Lydia WHITAKER, Auteur ; Catherine R. G. JONES, Auteur ; Arnold J. WILKINS, Auteur ; Debi ROBERSON, Auteur Article en page(s) : p.450-459 Langues : Anglais (eng) Mots-clés : facial expressions  sensory  autism spectrum disorder  tints  overlays  visual stress Index. décimale : PER Périodiques Résumé : Individuals with autism spectrum disorder (ASD) often show atypical processing of facial expressions, which may result from visual stress. In the current study, children with ASD and matched controls judged which member of a pair of faces displayed the more intense emotion. Both faces showed anger, disgust, fear, happiness, sadness or surprise but to different degrees. Faces were presented on a monitor that was tinted either gray or with a color previously selected by the participant individually as improving the clarity of text. Judgments of emotional intensity improved significantly with the addition of the preferred colored tint in the ASD group but not in controls, a result consistent with a link between visual stress and impairments in processing facial expressions in individuals with ASD.

When less is more: Poor discrimination but good colour memory in autism / Pamela HEATON in Research in Autism Spectrum Disorders, 2-1 (January/March 2008)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 2-1 (January/March 2008) . - p.147-156 Titre : When less is more: Poor discrimination but good colour memory in autism Type de document : Texte imprimé et/ou numérique Auteurs : Pamela HEATON, Auteur ; Amanda LUDLOW, Auteur ; Debi ROBERSON, Auteur Année de publication : 2008 Article en page(s) : p.147-156 Langues : Anglais (eng) Mots-clés : Autism Colour Perception Memory Index. décimale : PER Périodiques Résumé : In two experiments children with autism and two groups of controls matched for either chronological or non-verbal mental age were tested on tasks of colour discrimination and memory. The results from experiment 1 showed significantly poorer colour discrimination in children with autism in comparison to typically developing chronological age matched controls. However, in experiment 2, children with autism, retained unlabelled perceptual colour information to a significantly higher level than either group of controls. The findings suggest that enhanced performance on perceptual tasks relate to a reduced tendency to encode verbal information in memory.
