Visual Search and Emotion: How Children with Autism Spectrum Disorders Scan Emotional Scenes / Lisa MACCARI in Journal of Autism and Developmental Disorders, 44-11 (November 2014)
[article]
Titre : Visual Search and Emotion: How Children with Autism Spectrum Disorders Scan Emotional Scenes Type de document : Texte imprimé et/ou numérique Auteurs : Lisa MACCARI, Auteur ; Augusto PASINI, Auteur ; Emanuela CAROLI, Auteur ; Caterina ROSA, Auteur ; Andrea MAROTTA, Auteur ; Diana MARTELLA, Auteur ; LuisJ FUENTES, Auteur ; Maria CASAGRANDE, Auteur Article en page(s) : p.2871-2881 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders Change detection Change blindness Flicker task Visual search Emotional processing Index. décimale : PER Périodiques Résumé : This study assessed visual search abilities, tested through the flicker task, in children diagnosed with autism spectrum disorders (ASDs). Twenty-two children diagnosed with ASD and 22 matched typically developing (TD) children were told to detect changes in objects of central interest or objects of marginal interest (MI) embedded in either emotion-laden (positive or negative) or neutral real-world pictures. The results showed that emotion-laden pictures equally interfered with performance of both ASD and TD children, slowing down reaction times compared with neutral pictures. Children with ASD were faster than TD children, particularly in detecting changes in MI objects, the most difficult condition. However, their performance was less accurate than performance of TD children just when the pictures were negative. These findings suggest that children with ASD have better visual search abilities than TD children only when the search is particularly difficult and requires strong serial search strategies. The emotional–social impairment that is usually considered as a typical feature of ASD seems to be limited to processing of negative emotional information.
