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.

Titre : Executive Functions and Symptom Severity in an Italian Sample of Intellectually Able Preschoolers with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Giovanni VALERI, Auteur ; Laura CASULA, Auteur ; Eleonora NAPOLI, Auteur ; Paolo STIEVANO, Auteur ; Barbara TRIMARCO, Auteur ; Stefano VICARI, Auteur ; Teresa Gloria SCALISI, Auteur Article en page(s) : p.3207-3215 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Executive functions Inhibition Preschoolers Shifting Working memory Index. décimale : PER Périodiques Résumé : A novel battery (BAFE; Valeri et al. 2015) was used in order to assess three executive function (EF) abilities (working memory, inhibition and shifting) in a sample of 27 intellectually able preschoolers with autism spectrum disorder (ASD) compared with 27 typically developing children matched on age and nonverbal IQ. Differences in EF skills were analyzed in participants with distinct ASD symptom severity. Children with ASD performed worse than typical controls on both set-shifting and inhibition, but not on visuo-spatial working memory. Additionally, children with more severe ASD symptoms showed a worse performance on inhibition than children with milder symptoms. These results confirm the presence of EF deficits and highlight a link between ASD symptoms and EF impairments in preschool age.
