Public ISBD [article]  inJournal of Autism and Developmental Disorders > 39-3 (March 2009) . - p.471-479 Titre : Change Detection in Naturalistic Pictures Among Children with Autism Type de document : Texte imprimé et/ou numérique Auteurs : Jacob A. BURACK, Auteur ; Shari JOSEPH, Auteur ; Natalie RUSSO, Auteur ; David I. SHORE, Auteur ; Mafalda PORPORINO, Auteur ; James T. ENNS, Auteur Année de publication : 2009 Article en page(s) : p.471-479 Langues : Anglais (eng) Mots-clés : Change-detection Attention Development Index. décimale : PER Périodiques Résumé : Persons with autism often show strong reactions to changes in the environment, suggesting that they may detect changes more efficiently than typically developing (TD) persons. However, Fletcher-Watson et al. (Br J Psychol 97:537–554, 2006) reported no differences between adults with autism and TD adults with a change-detection task. In this study, we also found no initial differences in change-detection between children with autism and NVMA-matched TD children, although differences emerged when detection failures were related to the developmental level of the participants. Whereas detection failures decreased with increasing developmental level for TD children, detection failures remained constant over the same developmental range for children with autism, pointing to an atypical developmental trajectory for change-detection among children with autism.

Eye Tracking Effort Expenditure and Autonomic Arousal to Social and Circumscribed Interest Stimuli in Autism Spectrum Disorder / J. M. TRAYNOR in Journal of Autism and Developmental Disorders, 49-5 (May 2019)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 49-5 (May 2019) . - p.1988-2002 Titre : Eye Tracking Effort Expenditure and Autonomic Arousal to Social and Circumscribed Interest Stimuli in Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : J. M. TRAYNOR, Auteur ; A. GOUGH, Auteur ; E. DUKU, Auteur ; David I. SHORE, Auteur ; G. B. C. HALL, Auteur Article en page(s) : p.1988-2002 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Circumscribed interests  Eye tracking  Pupillometry  Repetitive behaviours  Social communication deficits Index. décimale : PER Périodiques Résumé : The social communicative deficits and repetitive behaviours seen in Autism Spectrum Disorder (ASD) may be affected by altered stimulus salience and reward attribution. The present study used eye tracking and a behavioural measure to index effort expenditure, arousal, and attention, during viewing of images depicting social scenes and subject-specific circumscribed interests in a group of 10 adults with ASD (mean age 25.4 years) and 19 typically-developing controls (mean age 20.7 years) Split-plot and one-way repeated measures ANOVAs were used to explore results. A significant difference between the ASD and control group was found in the amount of effort expended to view social and circumscribed images. The ASD group also displayed significant differences in pupillary response to social and circumscribed images, indicative of changes in autonomic arousal. Overall, the results support the social motivation hypothesis in ASD (Chevallier et al., Trends Cogn Sci 16(4):231-239, 2012) and suggest a role for autonomic arousal in the ASD symptom dyad.

Flexible Visual Processing in Young Adults with Autism: The Effects of Implicit Learning on a Global–Local Task / Dana HAYWARD in Journal of Autism and Developmental Disorders, 42-11 (November 2012)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 42-11 (November 2012) . - p.2383-2392 Titre : Flexible Visual Processing in Young Adults with Autism: The Effects of Implicit Learning on a Global–Local Task Type de document : Texte imprimé et/ou numérique Auteurs : Dana HAYWARD, Auteur ; David I. SHORE, Auteur ; Jelena RISTIC, Auteur ; Hanna KOVSHOFF, Auteur ; Grace IAROCCI, Auteur ; Laurent MOTTRON, Auteur ; Jacob A. BURACK, Auteur Article en page(s) : p.2383-2392 Langues : Anglais (eng) Mots-clés : High-functioning autism – Visual attention – Hierarchical figures – Implicit learning Index. décimale : PER Périodiques Résumé : We utilized a hierarchical figures task to determine the default level of perceptual processing and the flexibility of visual processing in a group of high-functioning young adults with autism (n = 12) and a typically developing young adults, matched by chronological age and IQ (n = 12). In one task, participants attended to one level of the figure and ignored the other in order to determine the default level of processing. In the other task, participants attended to both levels and the proportion of trials in which a target would occur at either level was manipulated. Both groups exhibited a global processing bias and showed similar flexibility in performance, suggesting that persons with autism may not be impaired in flexible shifting between task levels.
