Attentional shifts between audition and vision in Autism Spectrum Disorders / Valeria OCCELLI in Research in Autism Spectrum Disorders, 7-4 (April 2013)
[article]
Titre : Attentional shifts between audition and vision in Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Valeria OCCELLI, Auteur ; Gianluca ESPOSITO, Auteur ; Paola VENUTI, Auteur ; Giuseppe Maurizio ARDUINO, Auteur ; Massimiliano ZAMPINI, Auteur Article en page(s) : p.517-525 Langues : Anglais (eng) Mots-clés : Attention Shifting Autism Spectrum Disorders (ASDs) Multisensory Auditory Visual Index. décimale : PER Périodiques Résumé : Previous evidence on neurotypical adults shows that the presentation of a stimulus allocates the attention to its modality, resulting in faster responses to a subsequent target presented in the same (vs. different) modality. People with Autism Spectrum Disorders (ASDs) often fail to detect a (visual or auditory) target in a stream of stimuli after shifting attention between modalities, possibly because they do not fully switch their attention from one modality to the other. In this study, the performance of a group of high-functioning patients with ASDs and a group of neurotypical controls was compared. Participants were asked to detect a target, auditory or visual, which was preceded, at different temporal intervals (i.e., 150, 600, 1000 ms), by an uninformative cue, either in the same or a different modality. In controls, when the target was visual, the cue modality did not affect performance. Unlike, when the target was auditory, a visual cue produced longer reaction times as compared to when it was auditory. In the ASD group, irrespectively of the modality of the cue, a slowing-down of responses to the target was observed at increasing temporal intervals. The discrepancy of performance is consistent with the ‘over-focused’ theory of sensory processing.
