Mental imagery scanning in autism spectrum disorder / Katie L. MARAS in Research in Autism Spectrum Disorders, 8-10 (October 2014)
[article]
Titre : Mental imagery scanning in autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Katie L. MARAS, Auteur ; Marina C. WIMMER, Auteur ; Elizabeth J. ROBINSON, Auteur ; Dermot M. BOWLER, Auteur Article en page(s) : p.1416-1423 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Mental imagery Scanning Navigation Visuo-spatial processing Working memory Index. décimale : PER Périodiques Résumé : Navigational impairments have previously been reported in autism spectrum disorder (ASD). The present study examined the ability of individuals with ASD to generate and scan their mental image of a previously viewed map. Twenty-one ASD adults and 20 age- and IQ-matched comparison adults memorised a map of a fictitious island containing a number of landmarks. They then mentally imagined the map and were timed as they imagined a character walking between the various landmarks. Consistent with previous mental imagery research with typical individuals, there was a linear relationship between the time that participants took to mentally scan between the landmarks and the actual distance between the landmarks on the picture, and this was the case for both typical and ASD participants. ASD and comparison participants’ mental image scanning times were both also influenced by misleading signposts in the picture that indicated different distances between landmarks, thus providing evidence that their mental images were penetrable by top-down information. Although ASD and comparison participants showed very similar mental imagery scanning performance, verbal IQ and working memory were significantly and positively associated with image scanning performance for the ASD, but not the comparison group. This finding furthers the notion of a compensatory reliance on different strategies in ASD to achieve similar surface performance to individuals from the general population. Findings have practical implications for supporting navigation strategies in ASD.

Titre : Anxious Imagery in Children With and Without Autism Spectrum Disorder: An Investigation into Occurrence, Content, Features and Implications for Therapy Type de document : Texte imprimé et/ou numérique Auteurs : A. OZSIVADJIAN, Auteur ; M. J. HOLLOCKS, Auteur ; J. SOUTHCOTT, Auteur ; M. ABSOUD, Auteur ; E. HOLMES, Auteur Année de publication : 2017 Article en page(s) : p.3822-3832 Langues : Anglais (eng) Mots-clés : Anxiety Autism spectrum disorder (ASD) Mental imagery Index. décimale : PER Périodiques Résumé : Mental imagery has been implicated in anxiety disorders in adults, but has not been investigated in child and adolescent populations. Anxiety is highly prevalent in autism spectrum disorder (ASD), and as people with ASD are often thought of as 'visual thinkers', the potential role of distressing imagery in children with ASD merits exploration. Participants aged 8-16 years were grouped as follows: ASD/high anxiety, ASD/low anxiety, non-ASD/high anxiety and non-ASD/low anxiety. Imagery and associated features were assessed using an interview. Group differences were found in number and frequency of images experienced. There were few differences between the groups in the characteristics of the spontaneous images, which included emotional valence, vividness, controllability and realism. Implications for treatment are discussed. En ligne : http://dx.doi.org/10.1007/s10803-016-2840-3 Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=325

Titre : Thinking in Pictures as a Cognitive Account of Autism Type de document : Texte imprimé et/ou numérique Auteurs : Maithilee KUNDA, Auteur ; Ashok K. GOEL, Auteur Année de publication : 2011 Article en page(s) : p.1157-1177 Langues : Anglais (eng) Mots-clés : Autism Cognition Information processing Mental imagery Verbal representations Visual representations Visual reasoning Index. décimale : PER Périodiques Résumé : We analyze the hypothesis that some individuals on the autism spectrum may use visual mental representations and processes to perform certain tasks that typically developing individuals perform verbally. We present a framework for interpreting empirical evidence related to this “Thinking in Pictures” hypothesis and then provide comprehensive reviews of data from several different cognitive tasks, including the n-back task, serial recall, dual task studies, Raven’s Progressive Matrices, semantic processing, false belief tasks, visual search, spatial recall, and visual recall. We also discuss the relationships between the Thinking in Pictures hypothesis and other cognitive theories of autism including Mindblindness, Executive Dysfunction, Weak Central Coherence, and Enhanced Perceptual Functioning.
