During imitation, children with autism were less accurate than controls in replicating hand shape, hand orientation, and number of constituent limb movements. During shape tracing, children with autism performed accurately with direct visual feedback, but when viewing their hand in a mirror, some children with autism generated fewer errors than controls whereas others performed much worse. Large mirror drawing errors correlated with hand orientation and hand shape errors in imitation, suggesting that visuospatial information processing deficits may contribute importantly to functional motor coordination deficits in autism.

Electroencephalogram Coherence in Children With and Without Autism Spectrum Disorders: Decreased Interhemispheric Connectivity in Autism / Audrey M. CARSON in Autism Research, 7-3 (June 2014)  

Public ISBD [article]  inAutism Research > 7-3 (June 2014) . - p.334-343 Titre : Electroencephalogram Coherence in Children With and Without Autism Spectrum Disorders: Decreased Interhemispheric Connectivity in Autism Type de document : Texte imprimé et/ou numérique Auteurs : Audrey M. CARSON, Auteur ; Nicole M. G. SALOWITZ, Auteur ; Robert A. SCHEIDT, Auteur ; Bridget K. DOLAN, Auteur ; Amy VAUGHAN VAN HECKE, Auteur Article en page(s) : p.334-343 Langues : Anglais (eng) Mots-clés : electroencephaolography  EEG coherence  school age??pediatrics  social brain Index. décimale : PER Périodiques Résumé : Electroencephalogram coherence was measured in children with autism spectrum disorders (ASD) and control children at baseline and while watching videos of a familiar and unfamiliar person reading a story. Coherence was measured between the left and right hemispheres of the frontal, parietal, and temporal-parietal lobes (interhemispheric) and between the frontal and parietal lobes in each hemisphere (intrahemispheric). A data-reduction technique was employed to identify the frequency (alpha) that yielded significant differences in video conditions. Children with ASD displayed reduced coherence at the alpha frequency between the left and right temporal-parietal lobes in all conditions and reduced coherence at the alpha frequency between left and right frontal lobes during baseline. No group differences in intrahemispheric coherence at the alpha frequency emerged at the chosen statistical threshold. Results suggest decreased interhemispheric connectivity in frontal and temporal-parietal regions in children with ASD compared to controls.
