Tracking the Sensory Environment: An ERP Study of Probability and Context Updating in ASD / Marissa A. WESTERFIELD in Journal of Autism and Developmental Disorders, 45-2 (February 2015)
[article]
Titre : Tracking the Sensory Environment: An ERP Study of Probability and Context Updating in ASD Type de document : Texte imprimé et/ou numérique Auteurs : Marissa A. WESTERFIELD, Auteur ; Marla ZINNI, Auteur ; Khang VO, Auteur ; Jeanne TOWNSEND, Auteur Article en page(s) : p.600-611 Langues : Anglais (eng) Mots-clés : Autism ASD ERP Attention P3 Index. décimale : PER Périodiques Résumé : We recorded visual event-related brain potentials from 32 adult male participants (16 high-functioning participants diagnosed with autism spectrum disorder (ASD) and 16 control participants, ranging in age from 18 to 53 years) during a three-stimulus oddball paradigm. Target and non-target stimulus probability was varied across three probability conditions, whereas the probability of a third non-target stimulus was held constant in all conditions. P3 amplitude to target stimuli was more sensitive to probability in ASD than in typically developing participants, whereas P3 amplitude to non-target stimuli was less responsive to probability in ASD participants. This suggests that neural responses to changes in event probability are attention-dependant in high-functioning ASD. The implications of these findings for higher-level behaviors such as prediction and planning are discussed.
