STRAUSS, Auteur Année de publication : 2011 Article en page(s) : p.1609-1618 Langues : Anglais (eng) Mots-clés : Prototype  Autism  Face perception  Cognition Index. décimale : PER Périodiques Résumé : There is a growing amount of evidence suggesting that individuals with autism have difficulty with face processing. One basic cognitive ability that may underlie face processing difficulties is the ability to abstract a prototype. The current study examined prototype formation with natural faces using eye-tracking in high-functioning adults with autism and matched controls. Individuals with autism were found to have significant difficulty forming prototypes of natural faces. The eye-tracking data did not reveal any between group differences in the general pattern of attention to the faces, indicating that these difficulties were not due to attentional factors. Results are consistent with previous studies that have found a deficit in prototype formation and extend these deficits to natural faces.

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.
