MACARI, Auteur ; Sally J ROGERS, Auteur Année de publication : 2008 Article en page(s) : p.644-656 Langues : Anglais (eng) Mots-clés : Autism Motor Early-identification Index. décimale : PER Périodiques Résumé : Gross motor development (supine, prone, rolling, sitting, crawling, walking) and movement abnormalities were examined in the home videos of infants later diagnosed with autism (regression and no regression subgroups), developmental delays (DD), or typical development. Group differences in maturity were found for walking, prone, and supine, with the DD and Autism-No Regression groups both showing later developing motor maturity than typical children. The only statistically significant differences in movement abnormalities were in the DD group; the two autism groups did not differ from the typical group in rates of movement abnormalities or lack of protective responses. These findings do not replicate previous investigations suggesting that early motor abnormalities seen on home video can assist in early identification of autism.

Imitation in fragile X syndrome: Implications for autism / Marta MACEDONI-LUKSIC in Autism, 13-6 (November 2009)  

Public ISBD [article]  inAutism > 13-6 (November 2009) . - p.599-611 Titre : Imitation in fragile X syndrome: Implications for autism Type de document : Texte imprimé et/ou numérique Auteurs : Marta MACEDONI-LUKSIC, Auteur ; Randi J. HAGERMAN, Auteur ; Laura GREISS-HESS, Auteur ; David GOSAR, Auteur ; Kerrie LEMONS-CHITWOOD, Auteur ; Sally J ROGERS, Auteur Année de publication : 2009 Article en page(s) : p.599-611 Langues : Anglais (eng) Mots-clés : autism fragile-X-syndrome imitation Index. décimale : PER Périodiques Résumé : To address the specific impairment of imitation in autism, the imitation abilities of 22 children with fragile X syndrome (FXS) with and without autism were compared. Based on previous research, we predicted that children with FXS and autism would have significantly more difficulty with non-meaningful imitation tasks. After controlling for full-scale IQ and age, the groups did not differ in their overall imitation accuracy scores, but analysis of error patterns revealed that children with FXS and autism made more groping errors and additional movements than the comparison group. These error patterns are consistent with the hypothesis that an action production system deficit plays an important role in the overall imitation deficit in autism, at least in children with FXS.
