The Integration of Occlusion and Disparity Information for Judging Depth in Autism Spectrum Disorder / Danielle SMITH in Journal of Autism and Developmental Disorders, 47-10 (October 2017)
[article]
Titre : The Integration of Occlusion and Disparity Information for Judging Depth in Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Danielle SMITH, Auteur ; Danielle ROPAR, Auteur ; Harriet A. ALLEN, Auteur Article en page(s) : p.3112-3124 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Occlusion Disparity Cue integration Depth 3D Index. décimale : PER Périodiques Résumé : In autism spectrum disorder (ASD), atypical integration of visual depth cues may be due to flattened perceptual priors or selective fusion. The current study attempts to disentangle these explanations by psychophysically assessing within-modality integration of ordinal (occlusion) and metric (disparity) depth cues while accounting for sensitivity to stereoscopic information. Participants included 22 individuals with ASD and 23 typically developing matched controls. Although adults with ASD were found to have significantly poorer stereoacuity, they were still able to automatically integrate conflicting depth cues, lending support to the idea that priors are intact in ASD. However, dissimilarities in response speed variability between the ASD and TD groups suggests that there may be differences in the perceptual decision-making aspect of the task.

Titre : The Latent Structure of Autistic Traits: A Taxometric, Latent Class and Latent Profile Analysis of the Adult Autism Spectrum Quotient Type de document : Texte imprimé et/ou numérique Auteurs : Richard J. E. JAMES, Auteur ; Indu DUBEY, Auteur ; Danielle SMITH, Auteur ; Danielle ROPAR, Auteur ; Richard J. TUNNEY, Auteur Article en page(s) : p.3712-3728 Langues : Anglais (eng) Mots-clés : Autism quotient Autistic traits Taxometric analysis Latent class analysis Latent structure analysis Nosology Index. décimale : PER Périodiques Résumé : Autistic traits are widely thought to operate along a continuum. A taxometric analysis of Adult Autism Spectrum Quotient data was conducted to test this assumption, finding little support but identifying a high severity taxon. To understand this further, latent class and latent profile models were estimated that indicated the presence of six distinct subtypes: one with little probability of endorsing any autistic traits, one engaging in ‘systemising’ behaviours, three groups endorsing multiple components of Wing and Gould’s autistic triad, and a group similar in size and profile to the taxon previously identified. These analyses suggest the AQ (and potentially by extension autistic traits) have a categorical structure. These findings have important implications for the analysis and interpretation of AQ data.

Titre : Using Other Minds as a Window Onto the World: Guessing What Happened from Clues in Behaviour Type de document : Texte imprimé et/ou numérique Auteurs : Dhanya PILLAI, Auteur ; Elizabeth SHEPPARD, Auteur ; Danielle ROPAR, Auteur ; Lauren MARSH, Auteur ; Amy PEARSON, Auteur ; Peter MITCHELL, Auteur Article en page(s) : p.2430-2439 Langues : Anglais (eng) Mots-clés : Mentalising Retrodiction Social cognition Mental states Face processing Eye tracking Index. décimale : PER Périodiques Résumé : It has been proposed that mentalising involves retrodicting as well as predicting behaviour, by inferring previous mental states of a target. This study investigated whether retrodiction is impaired in individuals with autism spectrum disorders (ASD). Participants watched videos of real people reacting to the researcher behaving in one of four possible ways. Their task was to decide which of these four “scenarios” each person responded to. Participants’ eye movements were recorded. Participants with ASD were poorer than comparison participants at identifying the scenario to which people in the videos were responding. There were no group differences in time spent looking at the eyes or mouth. The findings imply those with ASD are impaired in using mentalising skills for retrodiction.

[article]
Titre : Visuo-tactile integration in autism: atypical temporal binding may underlie greater reliance on proprioceptive information Type de document : Texte imprimé et/ou numérique Auteurs : Katie GREENFIELD, Auteur ; Danielle ROPAR, Auteur ; Alastair D. SMITH, Auteur ; Mark CAREY, Auteur ; Roger NEWPORT, Auteur Article en page(s) : p.1-10 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Evidence indicates that social functioning deficits and sensory sensitivities in autism spectrum disorder (ASD) are related to atypical sensory integration. The exact mechanisms underlying these integration difficulties are unknown; however, two leading accounts are (1) an over-reliance on proprioception and (2) atypical visuo-tactile temporal binding. We directly tested these theories by selectively manipulating proprioceptive alignment and visuo-tactile synchrony to assess the extent that these impact upon body ownership.
