We examined neural responses to an implicit semantic priming task by comparing N400 responses-an event-related potential related to semantic processing-in response to semantically related or unrelated pairs of words or pictures. Adults with ASD showed larger N400 responses than typically developing adults for pictures, but no group differences occurred for words. However, we also observed complex modulations of N400 amplitude by age and by level of autistic traits. These results offer important implications for how groups are delineated and compared in autism research.

Linguistic and Non-Linguistic Semantic Processing in Individuals with Autism Spectrum Disorders: An ERP Study / Emily L. CODERRE in Journal of Autism and Developmental Disorders, 47-3 (March 2017)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 47-3 (March 2017) . - p.795-812 Titre : Linguistic and Non-Linguistic Semantic Processing in Individuals with Autism Spectrum Disorders: An ERP Study Type de document : texte imprimé Auteurs : Emily L. CODERRE, Auteur ; Mariya CHERNENOK, Auteur ; Barry GORDON, Auteur ; Kerry LEDOUX, Auteur Article en page(s) : p.795-812 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  Semantic processing  ERP  Language  Pictures Index. décimale : PER Périodiques Résumé : Individuals with autism spectrum disorders (ASD) experience difficulties with language, particularly higher-level functions like semantic integration. Yet some studies indicate that semantic processing of non-linguistic stimuli is not impaired, suggesting a language-specific deficit in semantic processing. Using a semantic priming task, we compared event-related potentials (ERPs) in response to lexico-semantic processing (written words) and visuo-semantic processing (pictures) in adults with ASD and adults with typical development (TD). The ASD group showed successful lexico-semantic and visuo-semantic processing, indicated by similar N400 effects between groups for word and picture stimuli. However, differences in N400 latency and topography in word conditions suggested different lexico-semantic processing mechanisms: an expectancy-based strategy for the TD group but a controlled post-lexical integration strategy for the ASD group.
