Electrophysiological Evidence of Atypical Spatial Attention in Those with a High Level of Self-reported Autistic Traits / Stephanie A. DUNN in Journal of Autism and Developmental Disorders, 46-6 (June 2016)
[article]
Titre : Electrophysiological Evidence of Atypical Spatial Attention in Those with a High Level of Self-reported Autistic Traits Type de document : Texte imprimé et/ou numérique Auteurs : Stephanie A. DUNN, Auteur ; Megan FREETH, Auteur ; Elizabeth MILNE, Auteur Article en page(s) : p.2199-2210 Langues : Anglais (eng) Mots-clés : Autistic traits ERP Selective attention Spatial attention N2pc Index. décimale : PER Périodiques Résumé : Selective attention is atypical in individuals with autism spectrum conditions. Evidence suggests this is also the case for those with high levels of autistic traits. Here we investigated the neural basis of spatial attention in those with high and low levels of self-reported autistic traits via analysis of ERP deflections associated with covert attention, target selection and distractor suppression (the N2pc, NT and PD). Larger N2pc and smaller PD amplitude was observed in those with high levels of autistic traits. These data provide neural evidence for differences in spatial attention, specifically, reduced distractor suppression in those with high levels of autistic traits, and may provide insight into the experience of perceptual overload often reported by individuals on the autism spectrum.

[article]
Titre : Attention to emotional tone of voice in speech perception in children with autism Type de document : Texte imprimé et/ou numérique Auteurs : Patricia J. BROOKS, Auteur ; Bertram O. PLOOG, Auteur Article en page(s) : p.845-857 Langues : Anglais (eng) Mots-clés : Affective prosody Selective attention Speech perception Video game Discrimination-choice procedure Index. décimale : PER Périodiques Résumé : A video game was developed to assess speech perception in 13 children with autism spectrum disorders (ASD) and 13 children with typical development (TYP), ages 5–17 years old. Children listened to pre-recorded sentences varying in content (e.g., “Bob parked a van” vs. “Tim shut a door”) and prosody (i.e., enthusiastic vs. grouchy tone of voice). During training, children learned to select one of two sentences differing in both content and prosody (e.g., enthusiastic “Bob parked a van” vs. grouchy “Tim shut a door”). At testing, children listened to test probes comprising re-combinations of the content and prosodic features of the training sentences. Testing indicated that both groups showed accurate discrimination of the training sentences from the re-combined test probes. However, whereas TYP children showed a preference to select the sentence with enthusiastic prosody over its grouchy counterpart, children with ASD did not. Thus, children with ASD show atypical attention to emotional tone of voice, even though they show no deficit in perceiving prosody.

However, the mechanisms underlying such auditory processing challenges are unknown. This preliminary study investigated auditory attention deployment in adults with ASD. Participants were instructed to maintain or switch attention between two simultaneous speech streams in three conditions: location (co-located versus?+?30° separation), voice (same voice versus male-female contrast), and both cues together. Results showed that individuals with ASD can selectively direct attention using location or voice cues, but performance was best when both cues were present. In comparison to neurotypical adults, overall performance was less accurate across all conditions. These findings warrant further investigation into auditory attention deployment differences in individuals with ASD.

[article]
Titre : Attentional status of faces for people with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Anna REMINGTON, Auteur ; Ruth CAMPBELL, Auteur ; John SWETTENHAM, Auteur Année de publication : 2012 Article en page(s) : p.59-73 Langues : Anglais (eng) Mots-clés : face processing selective attention perception Index. décimale : PER Périodiques Résumé : In recent years there has been a growing interest in the role of attention in the processing of social stimuli in individuals with autism spectrum disorders (ASD). Research has demonstrated that, for typical adults, faces have a special status in attention and are processed in an automatic and mandatory fashion even when participants attempt to ignore them. Under conditions of high load in a selective attention task, when irrelevant stimuli are usually not processed, typical adults continue to process distractor faces. Although there is evidence of a lack of attentional bias towards faces in ASD, there has been no direct test of whether faces are processed automatically using the distractor-face paradigm.In the present study 16 typical adults and 16 adults with ASD performed selective attention tasks with face and musical instrument distractors. The results indicated that even when the load of the central task was high, typical adults continued to be distracted by irrelevant face stimuli, whereas individuals with ASD were able to ignore them. In the equivalent non-social task, distractors had no effect at high load for either group. The results suggest that faces are processed in an automatic and mandatory fashion in typical adults but not in adults with ASD.

Titre : Contrasting the Effects of Task Difficulty and Perceptual Load on Auditory Detection Sensitivity in Individuals with Autism Type de document : Texte imprimé et/ou numérique Auteurs : J. TILLMANN, Auteur ; J. SWETTENHAM, Auteur Article en page(s) : p.762-772 Langues : Anglais (eng) Mots-clés : Auditory detection sensitivity Autism spectrum disorder Perceptual load Selective attention Task difficulty Index. décimale : PER Périodiques Résumé : To test a central assumption of the increased perceptual capacity account in individuals with Autism Spectrum Disorder (ASD), the effects of perceptual load and target-stimulus degradation on auditory detection sensitivity were contrasted. Fourteen adolescents with ASD and 16 neurotypical controls performed a visual letter search task under three conditions: low perceptual load, high perceptual load and low perceptual load with a degraded target while simultaneously detecting an auditory tone in noise. For both participants with ASD and neurotypical controls, increasing perceptual load and target degradation increased task difficulty as indexed by reaction times and accuracy. However, only increasing perceptual load reduced subsequent auditory detection sensitivity. The study confirms that perceptual load, and not task difficulty, modulates selective attention in ASD.
