Face and Object Discrimination in Autism, and Relationship to IQ and Age / Pamela M. PALLETT in Journal of Autism and Developmental Disorders, 44-5 (May 2014)
[article]
Titre : Face and Object Discrimination in Autism, and Relationship to IQ and Age Type de document : Texte imprimé et/ou numérique Auteurs : Pamela M. PALLETT, Auteur ; Shereen J. COHEN, Auteur ; Karen R. DOBKINS, Auteur Année de publication : 2014 Article en page(s) : p.1039-1054 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorders Face processing Object processing Inversion effects Adolescents Development Index. décimale : PER Périodiques Résumé : The current study tested fine discrimination of upright and inverted faces and objects in adolescents with Autism Spectrum Disorder (ASD) as compared to age- and IQ-matched controls. Discrimination sensitivity was tested using morphed faces and morphed objects, and all stimuli were equated in low-level visual characteristics (luminance, contrast, spatial frequency make-up). Participants with ASD exhibited slight, non-significant impairments in discrimination sensitivity for faces, yet significantly enhanced discrimination sensitivity for objects. The ASD group also showed a protracted development of face and object inversion effects. Finally, for ASD participants, face sensitivity improved with increasing IQ while object sensitivity improved with age. By contrast, for controls, face sensitivity improved with age, but neither face nor object sensitivity was influenced by IQ. These findings suggest that individuals with ASD follow a qualitatively different path in the development of face and object processing abilities.

Titre : The development of perceptual expertise for faces and objects in autism spectrum conditions Type de document : Texte imprimé et/ou numérique Auteurs : Cara R. DAMIANO, Auteur ; Owen CHURCHES, Auteur ; Howard RING, Auteur ; Simon BARON-COHEN, Auteur Année de publication : 2011 Article en page(s) : p.297-301 Langues : Anglais (eng) Mots-clés : face processing object processing autism spectrum conditions inversion effect perceptual expertise configural processing local processing Index. décimale : PER Périodiques Résumé : Previous research indicates that individuals with autism spectrum conditions (ASC) do not develop face expertise to the same extent as typical individuals. Yet it remains unclear whether this atypicality is specific to faces or related to more pervasive perceptual or cognitive deficits involved in the actual process of gaining expertise. To address this question, we examined the extent to which adults with ASC were capable of developing expertise with non-face objects. To become experts, all participants completed a 2-week training program with novel objects, known as Greebles. Level of expertise was assessed throughout training by measuring the ability to identify Greebles on an individual level. The perceptual strategies acquired as a result of expertise were measured through an inversion effect task completed before and after training, in which performance with upright Greebles and faces was compared to performance with inverted Greebles and faces. After expertise training, it was found that individuals in both the ASC and the typical group successfully achieved expertise and showed an enhanced Greeble inversion effect as a result of training. The development of an inversion effect with Greebles suggests that individuals with ASC may employ the same processing strategies as the typical group. Although exploratory, these findings have implications for understanding the nature of the face processing deficit in ASC as well as offering potential insights into face processing interventions for individuals with ASC.
