MEILLEUR, Auteur ; Marie-Pier POULIN-LORD, Auteur ; Michelle DAWSON, Auteur ; Isabelle SOULIERES, Auteur Article en page(s) : p.1-10 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : An important minority of school-aged autistic children, often characterized as ‘nonverbal’ or ‘minimally verbal,’ displays little or no spoken language. These children are at risk of being judged ‘low-functioning’ or ‘untestable’ via conventional cognitive testing practices. One neglected avenue for assessing autistic children so situated is to engage current knowledge of autistic cognitive strengths. Our aim was thus to pilot a strength-informed assessment of autistic children whose poor performance on conventional instruments suggests their cognitive potential is very limited.

Comparing Motor Skills in Autism Spectrum Individuals With and Without Speech Delay / Elise B. BARBEAU in Autism Research, 8-6 (December 2015)  

Public ISBD [article]  inAutism Research > 8-6 (December 2015) . - p.682-693 Titre : Comparing Motor Skills in Autism Spectrum Individuals With and Without Speech Delay Type de document : Texte imprimé et/ou numérique Auteurs : Elise B. BARBEAU, Auteur ; Andrée-Anne S. MEILLEUR, Auteur ; Thomas A. ZEFFIRO, Auteur ; Laurent MOTTRON, Auteur Article en page(s) : p.682-693 Langues : Anglais (eng) Mots-clés : autism spectrum  Asperger syndrome  motor skills  motor control  coordination  speech onset delay Index. décimale : PER Périodiques Résumé : Movement atypicalities in speed, coordination, posture, and gait have been observed across the autism spectrum (AS) and atypicalities in coordination are more commonly observed in AS individuals without delayed speech (DSM-IV Asperger) than in those with atypical or delayed speech onset. However, few studies have provided quantitative data to support these mostly clinical observations. Here, we compared perceptual and motor performance between 30 typically developing and AS individuals (21 with speech delay and 18 without speech delay) to examine the associations between limb movement control and atypical speech development. Groups were matched for age, intelligence, and sex. The experimental design included: an inspection time task, which measures visual processing speed; the Purdue Pegboard, which measures finger dexterity, bimanual performance, and hand-eye coordination; the Annett Peg Moving Task, which measures unimanual goal-directed arm movement; and a simple reaction time task. We used analysis of covariance to investigate group differences in task performance and linear regression models to explore potential associations between intelligence, language skills, simple reaction time, and visually guided movement performance. AS participants without speech delay performed slower than typical participants in the Purdue Pegboard subtests. AS participants without speech delay showed poorer bimanual coordination than those with speech delay. Visual processing speed was slightly faster in both AS groups than in the typical group. Altogether, these results suggest that AS individuals with and without speech delay differ in visually guided and visually triggered behavior and show that early language skills are associated with slower movement in simple and complex motor tasks.

Prevalence of Clinically and Empirically Defined Talents and Strengths in Autism / Andrée-Anne S. MEILLEUR in Journal of Autism and Developmental Disorders, 45-5 (May 2015)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 45-5 (May 2015) . - p.1354-1367 Titre : Prevalence of Clinically and Empirically Defined Talents and Strengths in Autism Type de document : Texte imprimé et/ou numérique Auteurs : Andrée-Anne S. MEILLEUR, Auteur ; Patricia JELENIC, Auteur ; Laurent MOTTRON, Auteur Article en page(s) : p.1354-1367 Langues : Anglais (eng) Mots-clés : Perception  Savant  Talent  Block  Pitch  Expertise Index. décimale : PER Périodiques Résumé : Outstanding skills, including special isolated skills (SIS) and perceptual peaks (PP) are frequent features of autism. However, their reported prevalence varies between studies and their co-occurrence is unknown. We determined the prevalence of SIS in a large group of 254 autistic individuals and searched for PP in 46 of these autistic individuals and 46 intelligence and age-matched typically developing controls. The prevalence of SIS among autistic individuals was 62.5 % and that of PP was 58 % (13 % in controls). The prevalence of SIS increased with intelligence and age. The existence of an SIS in a particular modality was not associated with the presence of a PP in the same modality. This suggests that talents involve an experience-dependent component in addition to genetically defined alterations of perceptual encoding.
