STRAUSS, Auteur Année de publication : 2012 Article en page(s) : p.1694-1704 Langues : Anglais (eng) Mots-clés : Categorization  Prototype  Autism  Cognition  Eye-tracking  Implicit Index. décimale : PER Périodiques Résumé : There is a growing amount of evidence suggesting that individuals with autism have difficulty with categorization. One basic cognitive ability that may underlie this difficulty is the ability to abstract a prototype. The current study examined prototype and category formation with dot patterns in high-functioning adults with autism and matched controls. Individuals with autism were found to have difficulty forming prototypes and categories of dot patterns. The eye-tracking data did not reveal any between group differences in attention to the dot patterns. However, relationships between performance and intelligence in the autism group suggest possible processing differences between the groups. Results are consistent with previous studies that have found deficits in prototype formation and extend these deficits to dot patterns.

A Lack of Left Visual Field Bias When Individuals with Autism Process Faces / Eva M. DUNDAS in Journal of Autism and Developmental Disorders, 42-6 (June 2012)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 42-6 (June 2012) . - p.1104-1111 Titre : A Lack of Left Visual Field Bias When Individuals with Autism Process Faces Type de document : Texte imprimé et/ou numérique Auteurs : Eva M. DUNDAS, Auteur ; Catherine A. BEST, Auteur ; Nancy J. MINSHEW, Auteur ; Mark S. STRAUSS, Auteur Année de publication : 2012 Article en page(s) : p.1104-1111 Langues : Anglais (eng) Mots-clés : Autism  Face processing  Left visual field (LVF) bias Index. décimale : PER Périodiques Résumé : It has been established that typically developing individuals have a bias to attend to facial information in the left visual field (LVF) more than in the right visual field. This bias is thought to arise from the right hemisphere’s advantage for processing facial information, with evidence suggesting it to be driven by the configural demands of face processing. Considering research showing that individuals with autism have impaired face processing abilities, with marked deficits in configural processing, it was hypothesized that they would not demonstrate a LVF bias for faces. Eye-tracking technology was used to show that individuals with autism were not spontaneously biased to facial information in the LVF, in contrast to a control group, while discriminating facial gender.

Left Visual Field Biases when Infants Process Faces: A Comparison of Infants at High- and Low-Risk for Autism Spectrum Disorder / Eva M. DUNDAS in Journal of Autism and Developmental Disorders, 42-12 (December 2012)

DUNDAS, Auteur ; Holly GASTGEB, Auteur ; Mark S. STRAUSS, Auteur Article en page(s) : p.2659-2668 Langues : Anglais (eng) Mots-clés : INFANTS  Autism  Face perception  Cognition Index. décimale : PER Périodiques Résumé : While it is well-known that individuals with autism spectrum disorder (ASD) have difficulties processing faces, very little is known about the origins of these deficits. The current study focused on 6- and 11-month-old infants who were at either high-risk (n = 43) or low-risk (n = 31) for developing ASD based on having a sibling already diagnosed with the disorder. Eye-tracking data were collected while the infants viewed color photographs of faces. Similar to previous studies with both typically developing adults and infants, low-risk infants demonstrated a preference for looking at the left side of the face (known as a left visual field bias) that emerged by 11 months of age. In contrast, high-risk infants did not demonstrate a left visual field bias at either age. Comparisons of the amount of attention given to the eye versus mouth regions indicated no differences between the two risk groups.
