Distinctive Role of Symbolic Number Sense in Mediating the Mathematical Abilities of Children with Autism / Alexis HINIKER in Journal of Autism and Developmental Disorders, 46-4 (April 2016)
[article]
Titre : Distinctive Role of Symbolic Number Sense in Mediating the Mathematical Abilities of Children with Autism Type de document : Texte imprimé et/ou numérique Auteurs : Alexis HINIKER, Auteur ; Miriam ROSENBERG-LEE, Auteur ; Vinod MENON, Auteur Année de publication : 2016 Article en page(s) : p.1268-1281 Langues : Anglais (eng) Mots-clés : Number sense Autism spectrum disorders Math ability Mathematiques Index. décimale : PER Périodiques Résumé : Despite reports of mathematical talent in autism spectrum disorders (ASD), little is known about basic number processing abilities in affected children. We investigated number sense, the ability to rapidly assess quantity information, in 36 children with ASD and 61 typically developing controls. Numerical acuity was assessed using symbolic (Arabic numerals) as well as non-symbolic (dot array) formats. We found significant impairments in non-symbolic acuity in children with ASD, but symbolic acuity was intact. Symbolic acuity mediated the relationship between non-symbolic acuity and mathematical abilities only in children with ASD, indicating a distinctive role for symbolic number sense in the acquisition of mathematical proficiency in this group. Our findings suggest that symbolic systems may help children with ASD organize imprecise information.

Titre : Sex differences in cortical volume and gyrification in autism Type de document : Texte imprimé et/ou numérique Auteurs : Marie SCHAER, Auteur ; John KOCHALKA, Auteur ; Aarthi PADMANABHAN, Auteur ; Kaustubh SUPEKAR, Auteur ; Vinod MENON, Auteur Article en page(s) : p.1-14 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Male predominance is a prominent feature of autism spectrum disorders (ASD), with a reported male to female ratio of 4:1. Because of the overwhelming focus on males, little is known about the neuroanatomical basis of sex differences in ASD. Investigations of sex differences with adequate sample sizes are critical for improving our understanding of the biological mechanisms underlying ASD in females.

Titre : Sex differences in structural organization of motor systems and their dissociable links with repetitive/restricted behaviors in children with autism Type de document : Texte imprimé et/ou numérique Auteurs : Kaustubh SUPEKAR, Auteur ; Vinod MENON, Auteur Article en page(s) : p.1-13 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) is diagnosed much less often in females than males. Emerging behavioral accounts suggest that the clinical presentation of autism is different in females and males, yet research examining sex differences in core symptoms of autism in affected children has been limited. Additionally, to date, there have been no systematic attempts to characterize neuroanatomical differences underlying the distinct behavioral profiles observed in girls and boys with ASD. This is in part because extant ASD studies have included a small number of girls.

Titre : The influence of sex and age on prevalence rates of comorbid conditions in autism Type de document : Texte imprimé et/ou numérique Auteurs : Kaustubh SUPEKAR, Auteur ; Tara IYER, Auteur ; Vinod MENON, Auteur Article en page(s) : p.778-789 Langues : Anglais (eng) Mots-clés : autism comorbidities epilepsy schizophrenia age sex Index. décimale : PER Périodiques Résumé : Individuals with ASD frequently experience one or more comorbid conditions. Here, we investigate the influence of sex and age—two important, yet understudied factors—on ten common comorbid conditions in ASD, using cross-sectional data from 4790 individuals with ASD and 1,842,575 individuals without ASD. Epilepsy, ADHD, and CNS/cranial anomalies showed exceptionally large proportions in both male (>19%) and female (>15%), children/adolescents with ASD. Notably, these prevalence rates decreased drastically with age in both males and females. In contrast, the prevalence of schizophrenia increased with age affecting a disproportionately large number of older (?35 year) adult males (25%), compared to females (7.7%), with ASD. Bowel disorders showed a complex U-pattern accompanied by changes in sex disparity with age. These results highlight crucial differences between cross-sectional comorbidity patterns and their interactions with sex and age, which may aid in the development of effective sex- and age-specific diagnostic/treatment strategies for ASD and comorbid conditions.
