The influence of static versus naturalistic stimuli on face processing in children with and without Asperger syndrome or high-functioning autism / Chiara HORLIN in Research in Autism Spectrum Disorders, 7-12 (December 2013)

Children with and without AS/HFA (n = 38) were fitted with a head-mounted eye-tracker and exposed to either static or interactive dynamic facial stimuli. Average fixation duration, the proportion of fixations in areas of interest and a comparative index that was independent of differences in presentation length between stimuli types were calculated. Visual scanning patterns of individuals with AS/HFA were not affected by stimuli type. However, control participants exhibited different scanning patterns between dynamic and static stimuli for certain regions of the face. Visual scanning patterns in children with AS/HFA are consistent regardless of the stimuli being a static photo or dynamic in the form of a real face. Hence, information from experimental studies with static photos of faces provide information that is valid and can be generalised to “real world” interactions.

Visual search strategies of children with and without autism spectrum disorders during an embedded figures task / Chiara HORLIN in Research in Autism Spectrum Disorders, 8-5 (May 2014)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 8-5 (May 2014) . - p.463-471 Titre : Visual search strategies of children with and without autism spectrum disorders during an embedded figures task Type de document : Texte imprimé et/ou numérique Auteurs : Chiara HORLIN, Auteur ; Matthew A. ALBRECHT, Auteur ; Marita FALKMER, Auteur ; Denise LEUNG, Auteur ; Anna ORDQVIST, Auteur ; Tele TAN, Auteur ; Wee Lih LEE, Auteur ; Torbjörn FALKMER, Auteur Article en page(s) : p.463-471 Mots-clés : ASD  Eye tracking  Embedded figures test  Visual search Index. décimale : PER Périodiques Résumé : Individuals with ASD often demonstrate superior performance on embedded figures tasks (EFTs). We investigated visual scanning behaviour in children with ASD during an EFT in an attempt replicating a previous study examining differences in visual search behaviour. Twenty-three children with, and 31 children without an ASD were shown 16 items from the Figure-Ground subtest of the TVPS-3 while wearing an eye tracker. Children with ASD exhibited fewer fixations, and less time per fixation, on the target figure. Accuracy was similar between the two groups. There were no other noteworthy differences between children with and without ASD. Differences in visual scanning patterns in the presence of typical behavioural performance suggest that any purported differences in processing style may not be detrimental to cognitive performance and further refinement of the current methodology may lead to support for a purported advantageous cognitive style.
