Drawing Firmer Conclusions: Autistic Children Show No Evidence of a Local Processing Bias in a Controlled Copying Task / Alastair D. SMITH in Journal of Autism and Developmental Disorders, 46-11 (November 2016)
[article]
Titre : Drawing Firmer Conclusions: Autistic Children Show No Evidence of a Local Processing Bias in a Controlled Copying Task Type de document : Texte imprimé et/ou numérique Auteurs : Alastair D. SMITH, Auteur ; Lorcan KENNY, Auteur ; Anna RUDNICKA, Auteur ; Josie BRISCOE, Auteur ; Elizabeth PELLICANO, Auteur Article en page(s) : p.3481-3492 Langues : Anglais (eng) Mots-clés : Autism Drawing Global Local Coherence Grouping Index. décimale : PER Périodiques Résumé : Drawing tasks are frequently used to test competing theories of visuospatial skills in autism. Yet, methodological differences between studies have led to inconsistent findings. To distinguish between accounts based on local bias or global deficit, we present a simple task that has previously revealed dissociable local/global impairments in neuropsychological patients. Autistic and typical children copied corner elements, arranged in a square configuration. Grouping cues were manipulated to test whether global properties affected the accuracy of reproduction. All children were similarly affected by these manipulations. There was no group difference in the reproduction of local elements, although global accuracy was negatively related to better local processing for autistic children. These data speak against influential theories of visuospatial differences in autism.

ALLEN, Auteur ; Eleanore CRAIG, Auteur Année de publication : 2016 Article en page(s) : p.704-712 Langues : Anglais (eng) Mots-clés : Imagination Drawing Planning Autism Learning disabilities Index. décimale : PER Périodiques Résumé : Here we examine imaginative drawing abilities in children with Autism Spectrum Disorder (ASD) and learning disabilities (LD) under several conditions: spontaneous production, with use of a template, and combining two real entities to form an ‘unreal’ entity. Sixteen children in each group, matched on mental and chronological age, were asked to draw a number of ‘impossible’ pictures of humans and dogs. Children with ASD were impaired in spontaneous drawings and included fewer impossible features than children with LD, but there was no difference when a template was provided. An autism-specific deficit was revealed in the task involving combining entities. Results suggest that children with ASD do not have a general imaginative deficit; impairment is instead related to planning demands.

Titre : Brief Report: New Evidence for a Social-Specific Imagination Deficit in Children with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Kayla D. TEN EYCKE, Auteur ; Ulrich MÜLLER, Auteur Article en page(s) : p.213-220 Langues : Anglais (eng) Mots-clés : Imagination Drawing Social deficits Autism Index. décimale : PER Périodiques Résumé : Previous research suggests that children with autism have deficits in drawing imaginative content. However, these conclusions are largely based on tasks that require children to draw impossible persons, and performance on this task may be limited by social deficits. To determine the generality of the deficit in imagination in children with autism, we asked 25 children with autism (mean age 9;7) and 29 neurotypically developing children (mean age 8;7) to draw an imaginative person and house. Drawings of imaginary houses by children with autism did not differ from those by neurotypically developing controls, but drawings of persons were significantly less imaginative. These findings suggest that the impairment in imagination among children with autism may be specific to social stimuli.

Titre : Partial occlusion depiction and its relationship with field independence in children with ASD Type de document : Texte imprimé et/ou numérique Auteurs : Eleanor S. HODGSON, Auteur ; Margaret MCGONIGLE-CHALMERS, Auteur Année de publication : 2011 Article en page(s) : p.473-495 Langues : Anglais (eng) Mots-clés : autism drawing field independence partial occlusion Index. décimale : PER Périodiques Résumé : We report a study of the depiction of partial occlusion and its relationship with field independence (FI) in children with ASD. Nineteen ASD children and 29 TD children (5;6—10;0) attempted to copy two 3D occluded scenes, and also selected the ‘best’ depiction of these scenes in drawings by others. ASD children were not significantly different from controls on FI but were significantly delayed in partial occlusion drawing and selection, independently of chronological age (CA), nonverbal mental age (NVMA) and FI. The results suggest that the depiction of partial occlusion in children with ASD is not qualitatively distinct from that in children with typical development but is significantly and specifically delayed.

Titre : Local Bias in Autistic Subjects as Evidenced by Graphic Tasks: Perceptual Hierarchization or Working Memory Deficit? Type de document : Texte imprimé et/ou numérique Auteurs : Laurent MOTTRON, Auteur ; Sylvie BELLEVILLE, Auteur ; Edith MENARD, Auteur Année de publication : 1999 Article en page(s) : p.743-755 Langues : Anglais (eng) Mots-clés : Autistic disorder drawing executive function hierarchical processing neuro-psychology visual perception working memory Index. décimale : PER Périodiques Résumé : In the present study, copying tasks were used to assess hierarchical aspects of visual perception in a group of 10 nonsavant autistic individuals with normal intelligence. In Experiment 1, the hierarchical order of graphic construction and the constancy of this order were measured for the copying of objects and nonobjects. In comparison to control participants, autistic individuals produced more local features at the start of the copying. However, they did not differ from controls with respect to graphic constancy. Experiment 2 measured the effect of geometrical impossibility on the copying of figures. Results revealed that autistic individuals were less affected by figure impossibility than were controls. Therefore, these experiments seem to support the notion of a local bias for visual information processing in individuals with autism. Two interpretations are proposed to account for this effect. According to the hierarchical deficit hypothesis, individuals with autism do not manifest the normal global bias in perceiving scenes and objects. Alternatively, the executive function hypothesis suggests that autism brings about limitations in the complexity of information that can be manipulated in short-term visual memory during graphic planning.
