Are Individuals with Autism and Asperger's Syndrome Susceptible to Visual Illusions ? / Danielle ROPAR in Journal of Child Psychology and Psychiatry, 40-8 (November 1999)
[article]
Titre : Are Individuals with Autism and Asperger's Syndrome Susceptible to Visual Illusions ? Type de document : Texte imprimé et/ou numérique Auteurs : Danielle ROPAR, Auteur ; Peter MITCHELL, Auteur Année de publication : 1999 Article en page(s) : p.1283-1293 Langues : Anglais (eng) Mots-clés : Autism Asperger's syndrome weak central coherence illusions Index. décimale : PER Périodiques Résumé : A recent finding that individuals with autism are not susceptible to illusions has been explained by Happé (1996) as a sign of “weak central coherence” at lower levels of processing. We investigated the phenomenon with a more sophisticated measure. In Experiment 1, individuals with autism, Asperger's syndrome, moderate learning difficulties, and typical development adjusted certain comparison lines and circles to make them appear to be the same size in four visual illusions. With a minor exception, the participants with autism and Asperger's syndrome evinced a systematic bias in their judgements in the illusion condition. The extent of this was no different from control participants. In a second experiment, a similar finding was obtained in a task where participants made verbal judgements about the stimuli. The results suggest that lower-level coherence in visual processing in autism is intact. Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=125

Titre : Attentional Differences in a Driving Hazard Perception Task in Adults with Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Elizabeth SHEPPARD, Auteur ; Editha VAN LOON, Auteur ; Geoffrey UNDERWOOD, Auteur ; Danielle ROPAR, Auteur Article en page(s) : p.405-414 Langues : Anglais (eng) Mots-clés : Attention Autism spectrum disorders Driving Eye-tracking Hazard perception Index. décimale : PER Périodiques Résumé : The current study explored attentional processing of social and non-social stimuli in ASD within the context of a driving hazard perception task. Participants watched videos of road scenes and detected hazards while their eye movements were recorded. Although individuals with ASD demonstrated relatively good detection of driving hazards, they were slower to orient to hazards. Greater attentional capture in the time preceding the hazards’ onset was associated with lower verbal IQ. The findings suggest that individuals with ASD may distribute and direct their attention differently when identifying driving hazards.

Titre : Autism and Dimensionality: Differences Between Copying and Drawing Tasks Type de document : Texte imprimé et/ou numérique Auteurs : Elizabeth SHEPPARD, Auteur ; Danielle ROPAR, Auteur ; Peter MITCHELL, Auteur Année de publication : 2009 Article en page(s) : p.1039-1046 Langues : Anglais (eng) Mots-clés : Autism Copying Drawing Perception Three-dimensionality Index. décimale : PER Périodiques Résumé : Previous research suggests individuals with autism may be less influenced by a three-dimensional interpretation when copying line drawings (Sheppard et al. J Autism Dev Disord 37:1913–1924, 2007). The current research aimed to determine whether this reduced dimensionality effect extends to drawings of an actual object. Twenty-four children and adolescents with autism and 24 comparison participants copied one line drawing with no depth cues, line drawings with a three-dimensional interpretation, and drew a actual three-dimensional object. Participants with autism were less influenced by three-dimensionality on the copying tasks but were equally affected when drawing the actual object. This suggests that any advantage for three-dimensional drawing in non-savant individuals with autism is confined to situations when the individual copies a line drawing with depth cues.

Titre : Autistic peer-to-peer information transfer is highly effective Type de document : Texte imprimé et/ou numérique Auteurs : Catherine J. CROMPTON, Auteur ; Danielle ROPAR, Auteur ; Claire V. M. EVANS-WILLIAMS, Auteur ; Emma G. FLYNN, Auteur ; Sue FLETCHER-WATSON, Auteur Article en page(s) : p.1704-1712 Langues : Anglais (eng) Mots-clés : *adults *communication and language *psychological theories of autism *social cognition and social behaviour Index. décimale : PER Périodiques Résumé : Sharing information with other people relies on the ability to communicate well. Autism is defined clinically by deficits in social communication. It may therefore be expected that autistic people find it difficult to share information with other people. We wanted to find out whether this was the case, and whether it was different when autistic people were sharing information with other autistic people or with non-autistic people. We recruited nine groups, each with eight people. In three of the groups, everyone was autistic; in three of the groups, everyone was non-autistic; and three of the groups were mixed groups where half the group was autistic and half the group was non-autistic. We told one person in each group a story and asked them to share it with another person, and for that person to share it again and so on, until everyone in the group had heard the story. We then looked at how many details of the story had been shared at each stage. We found that autistic people share information with other autistic people as well as non-autistic people do with other non-autistic people. However, when there are mixed groups of autistic and non-autistic people, much less information is shared. Participants were also asked how they felt they had got on with the other person in the interaction. The people in the mixed groups also experienced lower rapport with the person they were sharing the story with. This finding is important as it shows that autistic people have the skills to share information well with one another and experience good rapport, and that there are selective problems when autistic and non-autistic people are interacting.

Titre : Brief Report: A Comparison of the Preference for Viewing Social and Non-social Movies in Typical and Autistic Adolescents Type de document : Texte imprimé et/ou numérique Auteurs : Indu DUBEY, Auteur ; Danielle ROPAR, Auteur ; Antonia HAMILTON, Auteur Article en page(s) : p.514-519 Langues : Anglais (eng) Mots-clés : Choose-a-Movie (CAM) task Social preference Social motivation Autism spectrum conditions (ASC) Adolescents Index. décimale : PER Périodiques Résumé : The recently proposed Social Motivation theory (Chevallier et al., Trends in cognitive sciences 16(4):231–239, 2012) suggests that social difficulties in Autism Spectrum Condition (ASC) might be caused by a difference in the motivation to engage with other people. Here we compared adolescents with (N?=?31) and without (N?=?37) ASC on the Choose-a-Movie paradigm that measures the social seeking. The results showed a preference for viewing objects over smiling faces in ASC, which is in line with the theory of low social motivation. However, typical adolescents did not show any stimuli preferences, raising questions about developmental changes in social motivation. Age was found to play a significant role in moderating the choice behaviour of the participants. We discuss the implications of these findings in detail.
