Disentangling Neural Sources of the Motor Interference Effect in High Functioning Autism: An EEG-Study / Eliane DESCHRIJVER in Journal of Autism and Developmental Disorders, 47-3 (March 2017)
[article]
Titre : Disentangling Neural Sources of the Motor Interference Effect in High Functioning Autism: An EEG-Study Type de document : Texte imprimé et/ou numérique Auteurs : Eliane DESCHRIJVER, Auteur ; Jan R. WIERSEMA, Auteur ; Marcel BRASS, Auteur Article en page(s) : p.690-700 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Imitation N190 P3 Readiness potential Self-other distinction Index. décimale : PER Périodiques Résumé : The role of imitation in autism spectrum disorder (ASD) is controversial. Researchers have argued that deficient control of self- and other-related motor representations (self-other distinction) might explain imitation difficulties. In a recent EEG study, we showed that control of imitation relies on high-level as well as on low-level cognitive processes. Here, we aimed to further our insights into control of imitation deficits in ASD. We focused on congruency effects in the P3 (high-level), the N190 and the readiness potential (RP; low-level). We predicted smaller congruency effects within the P3 in the ASD group. However, we found differences in the RP and not in the P3-component. Thus, high-level self-other distinction centred on motor actions may be preserved in ASD, while impairments are reflected during motor preparation.
