WILKINSON, Auteur ; Catherine A. BEST, Auteur ; Nancy J. MINSHEW, Auteur ; Mark S. STRAUSS, Auteur Année de publication : 2010 Article en page(s) : p.1371-1377 Langues : Anglais (eng) Mots-clés : Autism  Face recognition  Memory awareness  Theory of mind  Metacognition Index. décimale : PER Périodiques Résumé : Little is known regarding metacognition in individuals with autism. Specifically, it is unclear how individuals with autism think about their own mental states. The current study assessed memory awareness during a facial recognition task. High-functioning children (M = 13.1 years, n = 18) and adults (M = 27.5 years, n = 16) with autism matched with typically developing children (M = 14.3 years, n = 13) and adults (M = 26.9 years, n = 15) were tested. Children with autism demonstrated less accurate memory awareness for faces and less reliable differentiation between their confidence ratings compared to typically developing children. Subtle impairments in memory awareness for faces were also evident in adults with autism. Results indicate that broader metacognitive deficits may exist in individuals with autism, possibly contributing to other known impairments.

Gender discrimination of eyes and mouths by individuals with autism / Catherine A. BEST in Autism Research, 3-2 (April 2010)  

Public ISBD [article]  inAutism Research > 3-2 (April 2010) . - p.88-93 Titre : Gender discrimination of eyes and mouths by individuals with autism Type de document : Texte imprimé et/ou numérique Auteurs : Catherine A. BEST, Auteur ; Nancy J. MINSHEW, Auteur ; Mark S. STRAUSS, Auteur Année de publication : 2010 Article en page(s) : p.88-93 Langues : Anglais (eng) Mots-clés : autism gender-discrimination face-perception facial-features Index. décimale : PER Périodiques Résumé : Evidence remains mixed about whether individuals with autism look less to eyes and whether they look more at mouths. Few studies have examined how spontaneous attention to facial features relates to face processing abilities. This study tested the ability to discriminate gender from facial features, namely eyes and mouths, by comparing accuracy scores of 17 children with autism and 15 adults with autism to 17 typically developing children and 15 typically developing adults. Results indicated that all participants regardless of diagnosis discriminated gender more accurately from eyes than from mouths. However, results indicated that compared to adults without autism, adults with autism were significantly worse at discriminating gender from eyes.

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)

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.

Prototype formation in autism: Can individuals with autism abstract facial prototypes? / Holly ZAJAC GASTGEB in Autism Research, 2-5 (October 2009)

STRAUSS, Auteur Année de publication : 2009 Article en page(s) : p.279-284 Langues : Anglais (eng) Mots-clés : prototype autism categorization face-perception Index. décimale : PER Périodiques Résumé : Prototype formation is a critical skill for category learning. Research suggests that individuals with autism may have a deficit in prototype formation of some objects; however, results are mixed. This study used a natural category, faces, to further examine prototype formation in high-functioning individuals with autism. High-functioning children (age 8-13 years) and adults with autism (age 17-53 years) and matched controls were tested in a facial prototype formation task that has been used to test prototype formation abilities in typically developing infants and adults [Strauss, [1979]]. Participants were familiarized to a series of faces depicting subtle variations in the spatial distance of facial features, and were then given a forced choice familiarity test between the mean prototype and the mode prototype. Overall, individuals in the autism group were significantly less likely to select the mean prototype face. Even though the children with autism showed this difference in prototype formation, this pattern was driven primarily by the adults, because the adults with autism were approximately four times less likely to select the mean prototype than were the control adults. These results provide further evidence that individuals with autism have difficulty abstracting subtle spatial information that is necessary not only for the formation of a mean prototype, but also for categorizing faces and objects.

The Development of Facial Gender Categorization in Individuals with and without Autism: The Impact of Typicality / Mark S. STRAUSS in Journal of Autism and Developmental Disorders, 42-9 (September 2012)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 42-9 (September 2012) . - p.1847-1855 Titre : The Development of Facial Gender Categorization in Individuals with and without Autism: The Impact of Typicality Type de document : Texte imprimé et/ou numérique Auteurs : Mark S.

The current study tested gender categorization abilities in high-functioning children (5–7 and 8–12 years), adolescents (13–17 years), and adults (18–53 years) with autism and matched controls. Naturalistic videos depicted faces that were either typical or less typical of each gender. Both groups improved in their performance across development. However, control children reached expertise that was similar to control adults by 8–12 years; whereas, adults with autism never reached this level of expertise, particularly with less typical gender faces. Results suggest that individuals with autism employ different face processing mechanisms than typically developing individuals.
