Children with Autism Detect Targets at Very Rapid Presentation Rates with Similar Accuracy as Adults / Carl Erick HAGMANN in Journal of Autism and Developmental Disorders, 46-5 (May 2016)
[article]
Titre : Children with Autism Detect Targets at Very Rapid Presentation Rates with Similar Accuracy as Adults Type de document : Texte imprimé et/ou numérique Auteurs : Carl Erick HAGMANN, Auteur ; Bradley WYBLE, Auteur ; Nicole SHEA, Auteur ; Megan LEBLANC, Auteur ; Wendy R. KATES, Auteur ; Natalie RUSSO, Auteur Article en page(s) : p.1762-1772 Langues : Anglais (eng) Mots-clés : Autism RSVP Visual search Attention Perception Cognition Development Index. décimale : PER Périodiques Résumé : Enhanced perception may allow for visual search superiority by individuals with Autism Spectrum Disorder (ASD), but does it occur over time? We tested high-functioning children with ASD, typically developing (TD) children, and TD adults in two tasks at three presentation rates (50, 83.3, and 116.7 ms/item) using rapid serial visual presentation. In the Color task, participants detected a purple target letter amongst black letter distractors. In the Category task, participants detected a letter amongst number distractors. Slower rates resulted in higher accuracy. Children with ASD were more accurate than TD children and similar to adults at the fastest rate when detecting color-marked targets, indicating atypical neurodevelopment in ASD may cause generalized perceptual enhancement relative to typically developing peers.

Titre : Examining the Temporal Limits of Enhanced Visual Feature Detection in Children With Autism Type de document : Texte imprimé et/ou numérique Auteurs : Justin KOPEC, Auteur ; Carl Erick HAGMANN, Auteur ; Nicole SHEA, Auteur ; Alyssa PRAWL, Auteur ; Daniel BATKIN, Auteur ; Natalie RUSSO, Auteur Article en page(s) : p.1561-1572 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The enhanced perceptual processing of visual features in children with autism spectrum disorder (ASD) is supported by an abundance of evidence in the spatial domain, with less robust evidence regarding whether this extends to information presented across time. The current study aimed to replicate and extend previous work finding that children with an ASD demonstrated enhanced perceptual accuracy in detecting feature-based (but not categorically defined) targets in time, when these were presented quickly, at a stimulus onset asynchrony (SOA) of 50?ms per item. Specifically, we extend the range of SOAs to examine the temporal boundaries of this enhanced accuracy and examine whether there is a relationship between ASD-related traits and detection accuracy on temporal visual search tasks. Individuals with autism perceived feature-based targets with statistically higher accuracy than their typically developing peers between SOAs of 39 and 65?ms and were numerically faster at all SOAs. No group differences were noted for category-based task accuracy. Our results also demonstrated that ASD-related traits measured by the autism spectrum quotient were positively correlated with accuracy on the feature-based task. Overall, results suggest that accurate visual perception of features (particularly color) is enhanced in children with ASD across time. Lay Summary Our results suggest that children with autism are able to process visual features, such as color, more accurately than typically developing children, even when these are presented very rapidly. Accuracy was higher in children with higher levels of autism-related traits and symptoms. Our findings suggest that more accurate visual perception exists not only across space in children with autism, as much of the existing literature demonstrates, but also over time.
