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.

In a series of three psychophysical experiments, we evaluated claims in the literature that individuals with ASD exhibit a deficit in voluntarily controlling the deployment and size of the spatial attention field. We measured the spatial distribution of performance accuracies and reaction times to quantify the sizes and locations of the attention field, with and without spatial uncertainty (i.e. the lack of predictability concerning the spatial position of the upcoming stimulus). We found that high-functioning adults with autism exhibited slower reaction times overall with spatial uncertainty, but the effects of attention on performance accuracies and reaction times were indistinguishable between individuals with autism and typically developing individuals in all three experiments. These results provide evidence of intact endogenous spatial attention function in high-functioning adults with ASD, suggesting that atypical endogenous attention cannot be a latent characteristic of autism in general.

Orienting and alerting attention systems were measured in 8-month-old infants using a spatial cueing paradigm. Results showed that only paternal autistic traits were linked to their children’s: (1) attentional disengagement; (2) rapid attentional orienting and (3) alerting. Our findings suggest that an early dysfunction of orienting and alerting systems might alter the developmental trajectory of future ability in social cognition and communication.

Titre : Multiple Object Tracking in Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Kami KOLDEWYN, Auteur ; Sarah WEIGELT, Auteur ; Nancy KANWISHER, Auteur ; Yuhong V. JIANG, Auteur Article en page(s) : p.1394-1405 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Multiple object tracking Dynamic attention Spatial attention Cognitive development Index. décimale : PER Périodiques Résumé : Difficulties in visual attention are often implicated in autism spectrum disorders (ASD) but it remains unclear which aspects of attention are affected. Here, we used a multiple object tracking (MOT) task to quantitatively characterize dynamic attentional function in children with ASD aged 5–12. While the ASD group performed significantly worse overall, the group difference did not increase with increased object speed. This finding suggests that decreased MOT performance is not due to deficits in dynamic attention but instead to a diminished capacity to select and maintain attention on multiple targets. Further, MOT performance improved from 5 to 10 years in both typical and ASD groups with similar developmental trajectories. These results argue against a specific deficit in dynamic attention in ASD.

However, leftward bias is reduced in autistic individuals viewing faces, and neurotypical individuals with autistic traits viewing ‘greyscale’ stimuli, suggestive of atypical lateralization of attention in autism. We investigated whether representational pseudoneglect for individuals with autistic traits is similarly atypically lateralized by comparing biases on a greyscales, landmark, and mental number line task. We found that pseudoneglect was intact only on the representational measure, the mental number line task, suggesting that mechanisms for atypical lateralization of attention in individuals with autistic traits are specific artefacts of processing physically visual stimuli.
