In general, the groups did not differ on measures of intelligence, working memory, attention, fluency and memory. For the monitoring of allocation of abstract figures, a similar pattern of reaction times was found for ASD and control participants. For the monitoring of allocation of semantically meaningful pictures, a different response pattern was found, with a stronger increase in response times for the ASD than for the control group when the number of categories increased. This suggests that participants with ASD are able to monitor working memory representations, but suffer under more complex circumstances.

The Interplay Between Attentional Strategies and Language Processing in High-functioning Adults with Autism Spectrum Disorder / Sophieke KOOLEN in Journal of Autism and Developmental Disorders, 42-5 (May 2012)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 42-5 (May 2012) . - p.805-814 Titre : The Interplay Between Attentional Strategies and Language Processing in High-functioning Adults with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Sophieke KOOLEN, Auteur ; Constance T.

HENDRIKS, Auteur ; Jos EGGER, Auteur ; Ludo VERHOEVEN, Auteur Année de publication : 2012 Article en page(s) : p.805-814 Langues : Anglais (eng) Mots-clés : Autism  Asperger’s disorder  Attention  Language;– Top-down control  Bottom-up processing Index. décimale : PER Périodiques Résumé : This study examined the hypothesis of an atypical interaction between attention and language in ASD. A dual-task experiment with three conditions was designed, in which sentences were presented that contained errors requiring attentional focus either at (a) low level, or (b) high level, or (c) both levels of language. Speed and accuracy for error detection were measured from 16 high-functioning adults with ASD, and 16 matched controls. For controls, there was an attentional cost of dual level processing for low level performance but not for high level performance. For participants with ASD, there was an attentional cost both for low level and for high level performance. These results suggest a compensatory strategic use of attention during language processing in ASD.
