Free Classification as a Window on Executive Functioning in Autism Spectrum Disorders / Margaret MCGONIGLE-CHALMERS in Journal of Autism and Developmental Disorders, 40-7 (July 2010)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 40-7 (July 2010) . - p.844-857 Titre : Free Classification as a Window on Executive Functioning in Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Margaret MCGONIGLE-CHALMERS, Auteur ; Ben ALDERSON-DAY, Auteur Année de publication : 2010 Article en page(s) : p.844-857 Langues : Anglais (eng) Mots-clés : Classification Sequencing Spontaneous-organization Top–down-processing Autism Index. décimale : PER Périodiques Résumé : Spontaneous classification was assessed using a free serial search task in 18 school-aged children at the high functioning end of the autistic spectrum and compared with results from age-matched typically developing controls. The task required participants to touch shapes in an exhaustive non-repetitive sequence. The positions of the items varied randomly between touches. The objective was to measure the extent to which children with autism and Asperger’s syndrome could spontaneously utilise category information such as shape and color to organise their search. There were no group differences on measures of sequential control and levels of categorization once age and IQ had been partialled out. The results are contrasted with findings from the same lab using a size seriation task.

Is It a Bird? Is It a Plane? Category Use in Problem-solving in Children with Autism Spectrum Disorders / Ben ALDERSON-DAY in Journal of Autism and Developmental Disorders, 41-5 (May 2011)

Category Use in Problem-solving in Children with Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Ben ALDERSON-DAY, Auteur ; Margaret MCGONIGLE-CHALMERS, Auteur Année de publication : 2011 Article en page(s) : p.555-565 Langues : Anglais (eng) Mots-clés : Autism  Categorisation  Problem-solving  Executive functioning Index. décimale : PER Périodiques Résumé : Fourteen children with autism spectrum disorders (ASD) and fourteen age-matched typically-developing (TD) controls were tested on an adapted version of the Twenty Questions Task (Mosher and Hornsby in Studies in cognitive growth. Wiley, New York, pp 86–102, 1966) to examine effects of content, executive and verbal IQ factors on category use in problem-solving (age range 8–17). Across conditions participants with ASD asked questions that focussed on smaller categories than controls. Specific group differences were observed in the handling of abstract content and response to additional working memory demands. In addition, post hoc regression analysis indicated that VIQ predicted performance in ASD but not TD participants. The implications for theories of category processing in autism are discussed.

Partial occlusion depiction and its relationship with field independence in children with ASD / Eleanor S. HODGSON in Autism, 15-4 (July 2011)  

Public ISBD [article]  inAutism > 15-4 (July 2011) . - p.473-495 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.

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.

Size Sequencing as a Window on Executive Control in Children with Autism and Asperger’s Syndrome / Margaret MCGONIGLE-CHALMERS in Journal of Autism and Developmental Disorders, 38-7 (August 2008)

BODNER, Auteur Année de publication : 2008 Article en page(s) : p.1382-1390 Langues : Anglais (eng) Mots-clés : Executive-functioning Autism Asperger’s-syndrome Working-memory Sequencing Index. décimale : PER Périodiques Résumé : A study is reported in which size sequencing on a touch screen is used as a measure of executive control in 20 high-functioning children with Autistic Spectrum Disorders (ASD). The data show a significant and age-independent effect of the length of sequence that can be executed without errors by these children, in comparison with a chronologically age-matched group of children with normal development. Error data and reaction times are analysed and are interpreted as revealing a constraint on the prospective component of working memory in children on the autistic spectrum even when there is no change in goal or perceptual set. It is concluded that the size sequencing paradigm is an effective measure of executive difficulties associated with autism.

Testing nonverbal IQ in children with Autism Spectrum Disorders / Nicole BARDIKOFF in Research in Autism Spectrum Disorders, 8-9 (September 2014)

No significant group differences were found for the PRI sub-scale of the WISC-IV nor for the nonverbal scale of the KABC-II, but the ASD group scored significantly lower than controls on the Processing Speed Index of the WISC-IV. This supports the need to isolate of timing criteria when IQ testing in populations with ASD, as is now the case with the WISC-IV. However significantly higher scores were obtained for the KABC-II versus the PRI for children with ASD only. The reasons for this are discussed with regard to a possible cultural bias in the Picture Concepts subtest of the WISC-IV.
