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.

Autism and Dimensionality: Differences Between Copying and Drawing Tasks / Elizabeth SHEPPARD in Journal of Autism and Developmental Disorders, 39-7 (July 2009)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 39-7 (July 2009) . - p.1039-1046 Titre : Autism and Dimensionality: Differences Between Copying and Drawing Tasks Type de document : Texte imprimé et/ou numérique Auteurs : Elizabeth SHEPPARD, Auteur ; Danielle ROPAR, Auteur ; Peter MITCHELL, Auteur Année de publication : 2009 Article en page(s) : p.1039-1046 Langues : Anglais (eng) Mots-clés : Autism Copying Drawing Perception Three-dimensionality Index. décimale : PER Périodiques Résumé : Previous research suggests individuals with autism may be less influenced by a three-dimensional interpretation when copying line drawings (Sheppard et al. J Autism Dev Disord 37:1913–1924, 2007). The current research aimed to determine whether this reduced dimensionality effect extends to drawings of an actual object. Twenty-four children and adolescents with autism and 24 comparison participants copied one line drawing with no depth cues, line drawings with a three-dimensional interpretation, and drew a actual three-dimensional object. Participants with autism were less influenced by three-dimensionality on the copying tasks but were equally affected when drawing the actual object. This suggests that any advantage for three-dimensional drawing in non-savant individuals with autism is confined to situations when the individual copies a line drawing with depth cues.

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.

Can Cartoons Which Depict Autistic Characters Improve Attitudes Towards Autistic Peers? / Carla Simone ENGEL in Journal of Autism and Developmental Disorders, 50-3 (March 2020)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 50-3 (March 2020) . - p.1007-1017 Titre : Can Cartoons Which Depict Autistic Characters Improve Attitudes Towards Autistic Peers? Type de document : Texte imprimé et/ou numérique Auteurs : Carla Simone ENGEL, Auteur ; Elizabeth SHEPPARD, Auteur Article en page(s) : p.1007-1017 Langues : Anglais (eng) Mots-clés : Autism  Cartoons  Conative component of attitudes  Knowledge  Peers  Vicarious contact Index. décimale : PER Périodiques Résumé : This study aimed to assess the efficacy of two cartoons which depict autistic characters in improving attitudes towards autistic peers in two separate studies. Forty-six children participated in study 1 (4-7 years), and 47 children participated in study 2 (8-11 years). Both the conative (behavioural) component of attitudes and knowledge about autism were measured before and after the cartoon interventions. Knowledge of autism increased after watching the cartoons in both studies but attitudes to autism only improved in study 1. Knowledge was shown to correlate with change in some but not all attitude measures. The findings suggest that cartoons can improve attitudes to autism, but this may depend on how information is presented.

A Cross-Cultural Comparison of Autistic Traits in the UK, India and Malaysia / Megan FREETH in Journal of Autism and Developmental Disorders, 43-11 (November 2013)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 43-11 (November 2013) . - p.2569-2583 Titre : A Cross-Cultural Comparison of Autistic Traits in the UK, India and Malaysia Type de document : Texte imprimé et/ou numérique Auteurs : Megan FREETH, Auteur ; Elizabeth SHEPPARD, Auteur ; Rajani RAMACHANDRAN, Auteur ; Elizabeth MILNE, Auteur Article en page(s) : p.2569-2583 Langues : Anglais (eng) Mots-clés : Culture  Autistic traits  Western  Eastern  India  Malaysia  UK Index. décimale : PER Périodiques Résumé : The disorder of autism is widely recognised throughout the world. However, the diagnostic criteria and theories of autism are based on research predominantly conducted in Western cultures. Here we compare the expression of autistic traits in a sample of neurotypical individuals from one Western culture (UK) and two Eastern cultures (India and Malaysia), using the Autism-spectrum Quotient (AQ) in order to identify possible cultural differences in the expression of autistic traits. Behaviours associated with autistic traits were reported to a greater extent in the Eastern cultures than the Western culture. Males scored higher than females and science students scored higher than non-science students in each culture. Indian students scored higher than both other groups on the Imagination sub-scale, Malaysian students scored higher than both other groups on the Attention Switching sub-scale. The underlying factor structures of the AQ for each population were derived and discussed.
