Does WISC-IV Underestimate the Intelligence of Autistic Children? / Anne-Marie NADER in Journal of Autism and Developmental Disorders, 46-5 (May 2016)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 46-5 (May 2016) . - p.1582-1589 Titre : Does WISC-IV Underestimate the Intelligence of Autistic Children? Type de document : Texte imprimé et/ou numérique Auteurs : Anne-Marie NADER, Auteur ; Valérie COURCHESNE, Auteur ; Michelle DAWSON, Auteur ; Isabelle SOULIERES, Auteur Article en page(s) : p.1582-1589 Langues : Anglais (eng) Mots-clés : Autism  Children  Intelligence  Wechsler scales  Raven’s progressive matrices  Abstract reasoning Index. décimale : PER Périodiques Résumé : Wechsler Intelligence Scale for Children (WISC) is widely used to estimate autistic intelligence (Joseph in The neuropsychology of autism. Oxford University Press, Oxford, 2011; Goldstein et al. in Assessment of autism spectrum disorders. Guilford Press, New York, 2008; Mottron in J Autism Dev Disord 34(1):19–27, 2004). However, previous studies suggest that while WISC-III and Raven’s Progressive Matrices (RPM) provide similar estimates of non-autistic intelligence, autistic children perform significantly better on RPM (Dawson et al. in Psychol Sci 18(8):657–662, doi: 10.1111/j.1467-9280.2007.01954.x , 2007). The latest WISC version introduces substantial changes in subtests and index scores; thus, we asked whether WISC-IV still underestimates autistic intelligence. Twenty-five autistic and 22 typical children completed WISC-IV and RPM. Autistic children’s RPM scores were significantly higher than their WISC-IV FSIQ, but there was no significant difference in typical children. Further, autistic children showed a distinctively uneven WISC-IV index profile, with a “peak” in the new Perceptual Reasoning Index. In spite of major changes, WISC-IV FSIQ continues to underestimate autistic intelligence.

Semantic and Visuospatial Fluid Reasoning in School-Aged Autistic Children / Anne-Marie NADER ; Janie DEGRE-PELLETIER ; Isabelle SOULIERES in Journal of Autism and Developmental Disorders, 53-12 (December 2023)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 53-12 (December 2023) . - p.4719-4730 Titre : Semantic and Visuospatial Fluid Reasoning in School-Aged Autistic Children Type de document : Texte imprimé et/ou numérique Auteurs : Anne-Marie NADER, Auteur ; Janie DEGRE-PELLETIER, Auteur ; Isabelle SOULIERES, Auteur Article en page(s) : p.4719-4730 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : In light of the known visuoperceptual strengths and altered language skills in autism, we investigated the impact of problem content (semantic/visuospatial) combined with complexity and presence of lures on fluid reasoning in 43 autistic and 41 typical children (6-13 years old). Increased complexity and presence of lures diminished performance, but less so as the children?s age increased. Typical children were slightly more accurate overall, whereas autistic children were faster at solving complex visuospatial problems. Thus, reasoning could rely more extensively on visuospatial strategies in autistic versus typical children. A combined speed-accuracy measure revealed similar performance in both groups, suggesting a similar pace in fluid reasoning development. Visual presentation of conceptual information seems to suit the reasoning processes of autistic children.
