Attentional Differences in a Driving Hazard Perception Task in Adults with Autism Spectrum Disorders / Elizabeth SHEPPARD in Journal of Autism and Developmental Disorders, 47-2 (February 2017)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 47-2 (February 2017) . - p.405-414 Titre : Attentional Differences in a Driving Hazard Perception Task in Adults with Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Elizabeth SHEPPARD, Auteur ; Editha VAN LOON, Auteur ; Geoffrey UNDERWOOD, Auteur ; Danielle ROPAR, Auteur Article en page(s) : p.405-414 Langues : Anglais (eng) Mots-clés : Attention  Autism spectrum disorders  Driving  Eye-tracking  Hazard perception Index. décimale : PER Périodiques Résumé : The current study explored attentional processing of social and non-social stimuli in ASD within the context of a driving hazard perception task. Participants watched videos of road scenes and detected hazards while their eye movements were recorded. Although individuals with ASD demonstrated relatively good detection of driving hazards, they were slower to orient to hazards. Greater attentional capture in the time preceding the hazards’ onset was associated with lower verbal IQ. The findings suggest that individuals with ASD may distribute and direct their attention differently when identifying driving hazards.

Brief Report: Driving Hazard Perception in Autism / Elizabeth SHEPPARD in Journal of Autism and Developmental Disorders, 40-4 (April 2010)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 40-4 (April 2010) . - p.504-508 Titre : Brief Report: Driving Hazard Perception in Autism Type de document : Texte imprimé et/ou numérique Auteurs : Elizabeth SHEPPARD, Auteur ; Danielle ROPAR, Auteur ; Geoffrey UNDERWOOD, Auteur ; Editha VAN LOON, Auteur Année de publication : 2010 Article en page(s) : p.504-508 Langues : Anglais (eng) Mots-clés : Autism Driving-hazards Social-processing Index. décimale : PER Périodiques Résumé : This study investigated whether individuals with ASD (autistic spectrum disorders) are able to identify driving hazards, given their difficulties processing social information, Klin et al. (Archives of General Psychiatry 59: 809–816, 2002). Twenty-three adult males with ASD and 21 comparison participants viewed 10 video clips containing driving hazards. In half of the clips the source of the hazard was a visible person (social); in the other half the source was a car (non-social). Participants with ASD identified fewer social hazards than the comparison participants (U = 163.00, N = 44, p < .05) but not non-social. Participants with ASD were also slower to respond than comparison participants, F(1,40) = 4.93, p < .05. This suggests that, although people with ASD can perceive driving hazards they may have specific difficulty identifying them if they involve a person.

Difficulties predicting time-to-arrival in individuals with autism spectrum disorders / Elizabeth SHEPPARD in Research in Autism Spectrum Disorders, 28 (August 2016)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 28 (August 2016) . - p.17-23 Titre : Difficulties predicting time-to-arrival in individuals with autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Elizabeth SHEPPARD, Auteur ; Editha VAN LOON, Auteur ; Geoffrey UNDERWOOD, Auteur ; Danielle ROPAR, Auteur Article en page(s) : p.17-23 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  Driving  Motion  Prediction impairment  Time-to-arrival Index. décimale : PER Périodiques Résumé : AbstractBackground Previous research suggests people with ASD may have various difficulties in processing and interacting with motion in the environment. We investigated whether individuals with ASD have difficulty judging the location of moving objects in a driving context using a time-to-arrival task. Methods Participants with and without ASD viewed scenes that simulated self-motion towards a junction, while another car approached on a side road. Scenes terminated prior to either car reaching the junction and participants were required to decide which car would reach the junction first. Results Participants with ASD made fewer correct responses although this was only true when self-motion was on a straight road. Conclusions This difficulty in judging the location of moving objects could contribute to difficulties people with ASD experience in learning to drive.
