Children with autism spectrum disorder spontaneously use scene knowledge to modulate visual object processing / Lien VAN EYLEN in Research in Autism Spectrum Disorders, 7-7 (July 2013)
[article]
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.

Titre : “I love the cute caterpillar!” autistic children's production of internal state language across contexts and relations to Joint Attention and theory of mind Type de document : Texte imprimé et/ou numérique Auteurs : Susanne KRISTEN, Auteur ; Maria VUORI, Auteur ; Beate SODIAN, Auteur Article en page(s) : p.22-33 Langues : Anglais (eng) Mots-clés : Internal state language Joint attention Theory of mind Context effects Index. décimale : PER Périodiques Résumé : Abstract Research on internal state language in autistic children reveals an uneven pattern. While some studies show that high-ability autistic children are impaired across a broad range of internal state term categories (e.g., desires, emotions and cognitive terms), other research shows that autistic children are more selectively impaired in their talk about cognitive states. Finally, some studies even demonstrate no impairments. The different findings have largely been explained by context effects. However, to date, studies have yet to compare the same children across different contexts to corroborate this interpretation. Further, studies involving contexts where autistic children's reactivity is actively triggered by providing clear joint attention cues or by exploiting autistic children's intense interest in objects are lacking. Thus, this study tested internal state language from different categories across three different contexts (narrative context, motivating mechanical toy context, elicited interactive joint attention context) and related it to joint attention skills and children's theory of mind. Results revealed that deficits in autistic children's internal state language were highly specific and relation to theory of mind varied by context. In sum, this research suggests that both theorists and practitioners need to take into account context when studying or promoting autistic individuals’ psychological comprehension.
