Cognitive Perspective-Taking During Scene Perception in Autism Spectrum Disorder: Evidence From Eye Movements / Sheena K. AU-YEUNG in Autism Research, 7-1 (February 2014)
[article]
Titre : Cognitive Perspective-Taking During Scene Perception in Autism Spectrum Disorder: Evidence From Eye Movements Type de document : Texte imprimé et/ou numérique Auteurs : Sheena K. AU-YEUNG, Auteur ; Johanna K. KAAKINEN, Auteur ; Valerie BENSON, Auteur Article en page(s) : p.84-93 Langues : Anglais (eng) Mots-clés : autism Asperger's syndrome theory of mind information processing eye movements scene perception Index. décimale : PER Périodiques Résumé : The present study examined how eye movements during scene viewing are modulated by adopting psychological perspectives in both adults with autism spectrum disorders (ASD) and typically developing adults. In the current study, participants viewed house scenes with either non-perspective-taking (look for valuable items/features of the house that need fixing) or perspective-taking instructions (imagine that you are a burglar/repairman) while their eye movements were recorded. The eye movement measures revealed that for the “look for the valuable items” and burglar perspective task, the ASD group showed typical relevance effects (the preference to look at schema-relevant compared with schema-irrelevant targets) in their eye movements. However, we found subtle processing differences between the groups that were related to initial orienting to and processing of schema-relevant items for the “look for the features that need fixing” and the repairman perspective-taking task. There was an absence of a relevance effect for the ASD group for the repairman perspective and its non-perspective-taking equivalent instruction showing that the identification of items relevant to those schemas was more difficult for the ASD group. The present findings suggest that resolving ambiguity may be a defining feature of complex information processing deficits in ASD.

[article]
Titre : Spatial Frequency Priming of Scene Perception in Adolescents With and Without ASD Type de document : Texte imprimé et/ou numérique Auteurs : Steven VANMARCKE, Auteur ; Ilse NOENS, Auteur ; Jean STEYAERT, Auteur ; Johan WAGEMANS, Auteur Article en page(s) : p.2023-2038 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders Scene perception Coarse-to-fine processing Spatial frequency Local–global information Index. décimale : PER Périodiques Résumé : While most typically developing (TD) participants have a coarse-to-fine processing style, people with autism spectrum disorder (ASD) seem to be less globally and more locally biased when processing visual information. The stimulus-specific spatial frequency content might be directly relevant to determine this temporal hierarchy of visual information processing in people with and without ASD. We implemented a semantic priming task in which (in)congruent coarse and/or fine spatial information preceded target categorization. Our results indicated that adolescents with ASD made more categorization errors than TD adolescents and needed more time to process the prime stimuli. Simultaneously, however, our findings argued for a processing advantage in ASD, when the prime stimulus contains detailed spatial information and presentation time permits explicit visual processing.

Titre : Children with autism spectrum disorder spontaneously use scene knowledge to modulate visual object processing Type de document : Texte imprimé et/ou numérique Auteurs : Lien VAN EYLEN, Auteur ; Peter DE GRAEF, Auteur ; Jean STEYAERT, Auteur ; Johan WAGEMANS, Auteur ; Ilse L.J. NOENS, Auteur Article en page(s) : p.913-922 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders Weak central coherence Context effects Scene perception Eye-movements Index. décimale : PER Périodiques Résumé : Several studies have investigated contextual influences on visual object processing in individuals with autism spectrum disorder (ASD) and failed to find reduced context effects. However, these studies did not properly account for local inter-object effects and/or the influence of post-perceptual processes, leaving it unclear whether individuals with ASD display equally large global top-down effects of context, or whether they rely on a more local mechanism producing the same result. In this study, an eye-movement paradigm was used to investigate implicitly induced context effects on visual object processing in children with ASD compared to matched controls. To find out whether the context effects in the ASD group were, to the same extent, due to early top-down influences on object recognition, we also examined the interaction between context effects and the ease of object recognition. Both groups displayed equally large context effects and congruent contextual information facilitated object recognition to the same extent in both groups. This indicates that the context effects in the ASD group did not result from the operation of a more local, less top-down mechanism. These findings contradict predictions based on the weak central coherence account. However, a good alternative to explain all inconsistencies is currently lacking.
