Atypical modulation of face-elicited saccades in autism spectrum disorder in a double-step saccade paradigm / Atsushi SENJU in Research in Autism Spectrum Disorders, 5-3 (July-September 2011)
[article]
Titre : Atypical modulation of face-elicited saccades in autism spectrum disorder in a double-step saccade paradigm Type de document : Texte imprimé et/ou numérique Auteurs : Atsushi SENJU, Auteur ; Yukiko KIKUCHI, Auteur ; Hironori AKECHI, Auteur ; Toshikazu HASEGAWA, Auteur ; Yoshikuni TOJO, Auteur ; Hiroo OSANAI, Auteur ; Mark H. JOHNSON, Auteur Année de publication : 2011 Article en page(s) : p.1264-1269 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Face processing Subcortical route Superior colliculus Double saccade Eye tracking Index. décimale : PER Périodiques Résumé : Atypical development of face processing is a major characteristic in autism spectrum disorder (ASD), which could be due to atypical interactions between subcortical and cortical face processing. The current study investigated the saccade planning towards faces in ASD. Seventeen children with ASD and 17 typically developing (TD) children observed a pair of upright or inverted face configurations flashed sequentially in two different spatial positions. The reactive saccades of participants were recorded by eye-tracking. The results did not provide evidence of overall impairment of subcortical route in ASD, However, the upright, but not the inverted, face configuration modulated the frequency of vector sum saccades (an index of subcortical control) in TD, but not in ASD. The current results suggest that children with ASD do not have overall impairment of the subcortical route, but the subcortical route may not be specialized to face processing.
