Brief Report: Suboptimal Auditory Localization in Autism Spectrum Disorder: Support for the Bayesian Account of Sensory Symptoms / Joshua C. SKEWES in Journal of Autism and Developmental Disorders, 46-7 (July 2016)

These difficulties have implications for communication, the development of social behavior, and quality of life. Recently, a theory has emerged which treats perceptual symptoms in ASD as the product of impairments in implicit Bayesian inference; as suboptimalities in the integration of sensory evidence with prior perceptual knowledge. We present the results of an experiment that applies this new theory to understanding difficulties in auditory localization, and we find that adults with ASD integrate prior information less optimally when making perceptual judgments about the spatial sources of sounds. We discuss these results in terms of their implications for formal models of symptoms in ASD.

Perceptual inference and autistic traits / Joshua C. SKEWES in Autism, 19-3 (April 2015)  

Public ISBD [article]  inAutism > 19-3 (April 2015) . - p.301-307 Titre : Perceptual inference and autistic traits Type de document : Texte imprimé et/ou numérique Auteurs : Joshua C. SKEWES, Auteur ; Else-Marie JEGINDØ, Auteur ; Line GEBAUER, Auteur Article en page(s) : p.301-307 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  perceptual enhancements  perceptual inference  signal detection theory  weak priors Index. décimale : PER Périodiques Résumé : Autistic people are better at perceiving details. Major theories explain this in terms of bottom-up sensory mechanisms or in terms of top-down cognitive biases. Recently, it has become possible to link these theories within a common framework. This framework assumes that perception is implicit neural inference, combining sensory evidence with prior perceptual knowledge. Within this framework, perceptual differences may occur because of enhanced precision in how sensory evidence is represented or because sensory evidence is weighted much higher than prior perceptual knowledge. In this preliminary study, we compared these models using groups with high and low autistic trait scores (Autism-Spectrum Quotient). We found evidence supporting the cognitive bias model and no evidence for the enhanced sensory precision model.
