Titre : Both the mirror and the affordance systems might be impaired in adults with high autistic traits. Evidence from EEG mu and beta rhythms Type de document : Texte imprimé et/ou numérique Auteurs : M. DE VEGA, Auteur ; I. PADRON, Auteur ; I. Z. MORENO, Auteur ; E. GARCIA-MARCO, Auteur ; A. DOMINGUEZ, Auteur ; H. MARRERO, Auteur ; S. HERNANDEZ, Auteur Année de publication : 2019 Article en page(s) : p.1032-1042 Langues : Anglais (eng) Mots-clés : affordances electroencephalography (EEG) mirror neuron system mu rhythms Index. décimale : PER Périodiques Résumé : The association of autism spectrum disorder (ASD) with an altered mirror neuron system is still controversial. At the same time, the processing of object affordances by persons with ASD is a neglected issue. In this electroencephalographic study, adults differing in their autism quotient (AQ) scores were selected. We found anomalous modulation of mu and beta rhythms in high-AQ, compared to low-AQ persons, while they watched a set of goal-directed manual actions. This confirms that observing actions involving implicit intentions most clearly reveals the impairment of the mirror neurons system (MNS). The high-AQ group also showed anomalous mu and beta modulation when they looked at pictures of manipulable objects, indicating a deficit in processing motor affordances. We conclude that high-AQ adults have neural impairment of both the MNS and the affordance systems, which could underlie their relational problems with both people and objects. Autism Res 2019, 12: 1032-1042. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Adults with autistic traits (high-autism quotient [AQ] scores) and matched controls (low-AQ) observed intentional hand actions, and pictures of manipulable and non-manipulable objects. The high-AQ group compared to the control group, showed anomalous modulation of the electroencephalographic motoric rhythms (mu and beta) while observing familiar goal-directed actions, confirming an impairment of their mirror neuron system. Also, their brain rhythms were anomalous when they watched manipulable objects, which suggest a dysfunction in their relation with objects (affordance system).

Titre : Facilitating Neurofeedback in Children with Autism and Intellectual Impairments Using TAGteach Type de document : Texte imprimé et/ou numérique Auteurs : K. LAMARCA, Auteur ; R. GEVIRTZ, Auteur ; A. J. LINCOLN, Auteur ; J. A. PINEDA, Auteur Article en page(s) : p.2090-2100 Langues : Anglais (eng) Mots-clés : Auditory secondary reinforcement Autism Conditioned reinforcement Intellectual impairment Low-functioning Mirror neurons Mu rhythms Neurofeedback TAGteach Index. décimale : PER Périodiques Résumé : Individuals with autism and intellectual impairments tend to be excluded from research due to their difficulties with methodological compliance. This study focuses on using Teaching with Acoustic Guidance-TAGteach-to behaviorally prepare children with autism and a IQ = 80 to participate in a study on neurofeedback training (NFT). Seven children (ages 6-8) learned the prerequisite skills identified in a task analysis in an average of 5 h of TAGteach training, indicating that this is a feasible method of preparing intellectually-impaired children with autism to participate in NFT and task-dependent electroencephalography measures. TAGteach may thus have the potential to augment this population's ability to participate in less accessible treatments and behavioral neuroscientific studies.
