Eighteen children with ASD and 19 age- and IQ-matched typically developing (TD) children were presented with semantically-congruent and incongruent picture-sound pairs, and in separate tasks were instructed to attend to only visual or both audio-visual sensory channels. Preliminary results showed that when required to attend to both modalities, both groups were equally slowed for semantically-incongruent compared to congruent pairs. However, when asked to attend to only visual information, children with ASD were disproportionally slowed by incongruent auditory information, suggesting that they may have more difficulty filtering task-irrelevant cross-modal information. Correlational analyses showed that this inefficient cross-modal attentional filtering was related to greater sociocommunicative impairment.

Guidelines and Best Practices for Electrophysiological Data Collection, Analysis and Reporting in Autism / Sara Jane WEBB in Journal of Autism and Developmental Disorders, 45-2 (February 2015)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 45-2 (February 2015) . - p.425-443 Titre : Guidelines and Best Practices for Electrophysiological Data Collection, Analysis and Reporting in Autism Type de document : Texte imprimé et/ou numérique Auteurs : Sara Jane WEBB, Auteur ; Raphael BERNIER, Auteur ; Heather A. HENDERSON, Auteur ; Mark H. JOHNSON, Auteur ; Emily J. H. JONES, Auteur ; Matthew D. LERNER, Auteur ; James C. MCPARTLAND, Auteur ; Charles A. NELSON, Auteur ; Donald C. ROJAS, Auteur ; Jeanne TOWNSEND, Auteur ; Marissa A. WESTERFIELD, Auteur Article en page(s) : p.425-443 Langues : Anglais (eng) Mots-clés : EEG  Electrophysiology  ERP  Event-related potentials  MEG  Magnetoencephalography  Autism  ASD  Guidelines Index. décimale : PER Périodiques Résumé : The EEG reflects the activation of large populations of neurons that act in synchrony and propagate to the scalp surface. This activity reflects both the brain’s background electrical activity and when the brain is being challenged by a task. Despite strong theoretical and methodological arguments for the use of EEG in understanding the neural correlates of autism, the practice of collecting, processing and evaluating EEG data is complex. Scientists should take into consideration both the nature of development in autism given the life-long, pervasive course of the disorder and the disability of altered or atypical social, communicative, and motor behaviors, all of which require accommodations to traditional EEG environments and paradigms. This paper presents guidelines for the recording, analyzing, and interpreting of EEG data with participants with autism. The goal is to articulate a set of scientific standards as well as methodological considerations that will increase the general field’s understanding of EEG methods, provide support for collaborative projects, and contribute to the evaluation of results and conclusions.

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)

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.
