Cognitive Mechanisms underlying visual perspective taking in typical and ASC children / Amy PEARSON in Autism Research, 9-1 (January 2016)  

Public ISBD [article]  inAutism Research > 9-1 (January 2016) . - p.121-130 Titre : Cognitive Mechanisms underlying visual perspective taking in typical and ASC children Type de document : Texte imprimé et/ou numérique Auteurs : Amy PEARSON, Auteur ; Lauren MARSH, Auteur ; Danielle ROPAR, Auteur ; Antonia HAMILTON, Auteur Article en page(s) : p.121-130 Langues : Anglais (eng) Mots-clés : autism spectrum conditions  visual perspective taking  mental rotation  embodied  cognitive mechanisms Index. décimale : PER Périodiques Résumé : Previous research has suggested that people with Autism Spectrum Conditions (ASC) may have difficulty with visual perspective taking (VPT) but it is not clear how this relates to different strategies that can be used in perspective taking tasks. The current study examined VPT in 30 children with autism and 30 verbal mental age matched typical children, in comparison to mental rotation (MR) abilities and body representation abilities. Using a similar paradigm to Hamilton, Brindley, and Frith [2009] all children completed three tasks: a VPT task in which children decided what a toy on a table would look like from a different points of view; a MR task in which the child decided what a toy would look like after it had been rotated; and a body posture matching task, in which children matched pictures of a body shown from different viewpoints. Results showed that children with ASC performed better than the typically developing children on the MR task, and at a similar level on the VPT task and body matching task. Importantly, in the typical children VPT performance was predicted by performance on the body matching task, whereas in the ASC children VPT performance was predicted by MR ability. These findings suggest that differences in VPT in ASC may be explained by the use of a spatial rotation strategy rather than the embodied egocentric transformation strategy used by typical children.

Spatial Transformations of Bodies and Objects in Adults with Autism Spectrum Disorder / Amy PEARSON in Journal of Autism and Developmental Disorders, 44-9 (September 2014)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 44-9 (September 2014) . - p.2277-2289 Titre : Spatial Transformations of Bodies and Objects in Adults with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Amy PEARSON, Auteur ; Lauren MARSH, Auteur ; Antonia HAMILTON, Auteur ; Danielle ROPAR, Auteur Article en page(s) : p.2277-2289 Langues : Anglais (eng) Mots-clés : Spatial transformations  Bodies  Objects  Mental rotation  Egocentric  Autism Index. décimale : PER Périodiques Résumé : Previous research into autism spectrum disorder (ASD) has shown people with autism to be impaired at visual perspective taking. However it is still unclear to what extent the spatial mechanisms underlying this ability contribute to these difficulties. In the current experiment we examine spatial transformations in adults with ASD and typical adults. Participants performed egocentric transformations and mental rotation of bodies and cars. Results indicated that participants with ASD had general perceptual differences impacting on response times across tasks. However, they also showed more specific differences in the egocentric task suggesting particular difficulty with using the self as a reference frame. These findings suggest that impaired perspective taking could be grounded in difficulty with the spatial transformation used to imagine the self in someone else’s place.

Using Other Minds as a Window Onto the World: Guessing What Happened from Clues in Behaviour / Dhanya PILLAI in Journal of Autism and Developmental Disorders, 44-10 (October 2014)

This study investigated whether retrodiction is impaired in individuals with autism spectrum disorders (ASD). Participants watched videos of real people reacting to the researcher behaving in one of four possible ways. Their task was to decide which of these four “scenarios” each person responded to. Participants’ eye movements were recorded. Participants with ASD were poorer than comparison participants at identifying the scenario to which people in the videos were responding. There were no group differences in time spent looking at the eyes or mouth. The findings imply those with ASD are impaired in using mentalising skills for retrodiction.
