Seeing the Forest and the Trees: Default Local Processing in Individuals with High Autistic Traits Does Not Come at the Expense of Global Attention / R. A. STEVENSON in Journal of Autism and Developmental Disorders, 48-4 (April 2018)

We investigated whether local-processing biases were associated with global-processing impairments on a global/local attentional-scope paradigm in conjunction with a composite-face task. Behavioural results were related to individuals' levels of autistic traits, specifically the Attention to Detail subscale of the Autism Quotient, and the Sensory Profile Questionnaire. Individuals showing high rates of Attention to Detail were more susceptible to global attentional-scope manipulations, suggesting that local-processing biases associated with Attention to Detail do not come at the cost of a global-processing deficit, but reflect a difference in default global versus local bias. This relationship operated at the attentional/perceptual level, but not response criterion.

The cascading influence of multisensory processing on speech perception in autism / R. A. STEVENSON in Autism, 22-5 (July 2018)  

Public ISBD [article]  inAutism > 22-5 (July 2018) . - p.609-624 Titre : The cascading influence of multisensory processing on speech perception in autism Type de document : Texte imprimé et/ou numérique Auteurs : R. A. STEVENSON, Auteur ; M. SEGERS, Auteur ; B. L. NCUBE, Auteur ; Karen R. BLACK, Auteur ; James M. BEBKO, Auteur ; S. FERBER, Auteur ; Morgan D. BARENSE, Auteur Article en page(s) : p.609-624 Langues : Anglais (eng) Mots-clés : audiovisual  autism spectrum disorder  multisensory  sensory integration  speech perception  temporal processing Index. décimale : PER Périodiques Résumé : It has been recently theorized that atypical sensory processing in autism relates to difficulties in social communication. Through a series of tasks concurrently assessing multisensory temporal processes, multisensory integration and speech perception in 76 children with and without autism, we provide the first behavioral evidence of such a link. Temporal processing abilities in children with autism contributed to impairments in speech perception. This relationship was significantly mediated by their abilities to integrate social information across auditory and visual modalities. These data describe the cascading impact of sensory abilities in autism, whereby temporal processing impacts multisensory information of social information, which, in turn, contributes to deficits in speech perception. These relationships were found to be specific to autism, specific to multisensory but not unisensory integration, and specific to the processing of social information.
