Early Lateralization of Gestures in Autism: Right-Handed Points Predict Expressive Language / Nevena DIMITROVA in Journal of Autism and Developmental Disorders, 50-4 (April 2020)
[article]
Titre : Early Lateralization of Gestures in Autism: Right-Handed Points Predict Expressive Language Type de document : Texte imprimé et/ou numérique Auteurs : Nevena DIMITROVA, Auteur ; Christine MOHR, Auteur ; ?eyda ÖZÇALI?KAN, Auteur ; Lauren B. ADAMSON, Auteur Article en page(s) : p.1147-1158 Langues : Anglais (eng) Mots-clés : Autism Gesture Hand preference Language development Laterality Pointing Index. décimale : PER Périodiques Résumé : Children with autism spectrum disorder (ASD) produce fewer deictic gestures, accompanied by delays/deviations in speech development, compared to typically-developing (TD) children. We ask whether children with ASD-like TD children-show right-hand preference in gesturing and whether right-handed gestures predict their vocabulary size in speech. Our analysis of handedness in gesturing in children with ASD (n = 23, Mage = 30-months) and with TD (n = 23, Mage = 18-months) during mother-child play showed a right-hand preference for TD children-but not for children with ASD. Nonetheless, right-handed deictic gestures predicted expressive vocabulary 1 year later in both children with ASD and with TD. Handedness for gesture, both hand preference and amount of right-handed pointing, may be an important indicator of language development in autism and typical development.

Titre : There Are Indeed More Left-Handers Within the Autism Spectrum Disorder Compared with in the General Population, but the Many Mixed-Handers Is the More Interesting Finding Type de document : Texte imprimé et/ou numérique Auteurs : A. L. RYSSTAD, Auteur ; A. V. PEDERSEN, Auteur Article en page(s) : p.3253-3255 Langues : Anglais (eng) Mots-clés : Ambilateral Hand dominance Hand preference Laterality Index. décimale : PER Périodiques Résumé : Letter to the editor in response to Howard Kushner's claims that our data on non-right-handedness within the autism spectrum disorder were organized, by sleight of hand, so they would give a significant result that would support our desired conclusion. Here, we have re-categorized our data, and present evidence that there are indeed more left-handers within the ASD. Furthermore, we refute claims that we have misinterpreted our results in order to conclude about a causal link between left-handedness and ASD, and highlight our original suggestion that mixed-handedness, more specifically unclear handedness, is the bigger problem, and that our findings of a total 60% non-right-handedness was the more interesting finding.
