Atypical Disengagement from Faces and Its Modulation by the Control of Eye Fixation in Children with Autism Spectrum Disorder / Yukiko KIKUCHI in Journal of Autism and Developmental Disorders, 41-5 (May 2011)
[article]
Titre : Atypical Disengagement from Faces and Its Modulation by the Control of Eye Fixation in Children with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Yukiko KIKUCHI, Auteur ; Atsushi SENJU, Auteur ; Hironori AKECHI, Auteur ; Yoshikuni TOJO, Auteur ; Hiroo OSANAI, Auteur ; Toshikazu HASEGAWA, Auteur Année de publication : 2011 Article en page(s) : p.629-645 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Face Disengagement Saccade-related ERPs Gap overlap task Index. décimale : PER Périodiques Résumé : By using the gap overlap task, we investigated disengagement from faces and objects in children (9–17 years old) with and without autism spectrum disorder (ASD) and its neurophysiological correlates. In typically developing (TD) children, faces elicited larger gap effect, an index of attentional engagement, and larger saccade-related event-related potentials (ERPs), compared to objects. In children with ASD, by contrast, neither gap effect nor ERPs differ between faces and objects. Follow-up experiments demonstrated that instructed fixation on the eyes induces larger gap effect for faces in children with ASD, whereas instructed fixation on the mouth can disrupt larger gap effect in TD children. These results suggest a critical role of eye fixation on attentional engagement to faces in both groups.

FRANCIS, Auteur Article en page(s) : p.3999-4008 Langues : Anglais (eng) Mots-clés : Attention Auditory Autism spectrum disorder Disengagement Eog Eye movements Index. décimale : PER Périodiques Résumé : Despite early differences in orienting to sounds, no study to date has investigated whether children with ASD demonstrate impairments in attentional disengagement in the auditory modality. Twenty-one 9-15-year-old children with ASD and 20 age- and IQ-matched TD children were presented with an auditory gap-overlap paradigm. Evidence of impaired disengagement in ASD was mixed. Differences in saccadic reaction time for overlap and gap conditions did not differ between groups. However, children with ASD did show increased no-shift trials in the overlap condition, as well as reduced disengagement efficiency compared to their TD peers. These results provide further support for disengagement impairments in ASD, and suggest that these deficits include disengaging from and shifting to unimodal auditory information.

Type de document : Texte imprimé et/ou numérique Auteurs : Lien VAN EYLEN, Auteur ; Bart BOETS, Auteur ; Jean STEYAERT, Auteur ; Kris EVERS, Auteur ; Johan WAGEMANS, Auteur ; Ilse L.J. NOENS, Auteur Année de publication : 2011 Article en page(s) : p.1390-1401 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders Cognitive flexibility Task-switching Wisconsin Card Sorting Task Disengagement Task instructions Index. décimale : PER Périodiques Résumé : The Wisconsin Card Sorting Task (WCST) is the only cognitive flexibility task that has consistently shown deficits in individuals with an autism spectrum disorder (ASD). As this is the only task characterized by limited explicit task instructions and a high degree of disengagement required to perform the switch, we hypothesized that cognitive flexibility deficits of individuals with ASD might only become apparent in situations fulfilling these requirements. However, the WCST involves various additional cognitive processes besides switching, making it uncertain whether difficulties are indeed due to cognitive flexibility impairments. The aim of this study was to investigate whether individuals with ASD show cognitive flexibility impairments on a more controlled task-switching variant of the WCST, still fulfilling both requirements. We therefore developed such a task and administered it to 40 high-functioning children with ASD and 40 age- and IQ- matched typically developing controls. As predicted, individuals with ASD made more perseveration errors and had a significantly higher switch cost than typically developing controls, but they performed equally well on the control measures.
