Functional but Inefficient Kinesthetic Motor Imagery in Adolescents with Autism Spectrum Disorder / Y. T. CHEN in Journal of Autism and Developmental Disorders, 48-3 (March 2018)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 48-3 (March 2018) . - p.784-795 Titre : Functional but Inefficient Kinesthetic Motor Imagery in Adolescents with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Y. T. CHEN, Auteur ; K. S. TSOU, Auteur ; H. L. CHEN, Auteur ; C. C. WONG, Auteur ; Y. T. FAN, Auteur ; C. T. WU, Auteur Année de publication : 2018 Article en page(s) : p.784-795 Langues : Anglais (eng) Mots-clés : Action representation  Autism spectrum disorder  Motor cognition  Motor imagery Index. décimale : PER Périodiques Résumé : Whether action representation in individuals with autism spectrum disorder (ASD) is deficient remains controversial, as previous studies of action observation or imitation report conflicting results. Here we investigated the characteristics of action representation in adolescents with ASD through motor imagery (MI) using a hand rotation and an object rotation task. Comparable with the typically-developing group, the individuals with ASD were able to spontaneously use kinesthetic MI to perform the hand rotation task, as manifested by the significant biomechanical effects. However, the ASD group performed significantly slower only in the hand rotation task, but not in the object rotation task. The findings suggest that the adolescents with ASD showed inefficient but functional kinesthetic MI, implicating that their action representation might be preserved.

Motor network activation during human action observation and imagery: Mu rhythm EEG evidence on typical and atypical neurodevelopment / Olivia Morgan LAPENTA in Research in Autism Spectrum Disorders, 8-7 (July 2014)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 8-7 (July 2014) . - p.759-766 Titre : Motor network activation during human action observation and imagery: Mu rhythm EEG evidence on typical and atypical neurodevelopment Type de document : Texte imprimé et/ou numérique Auteurs : Olivia Morgan LAPENTA, Auteur ; Paulo Sérgio BOGGIO, Auteur Article en page(s) : p.759-766 Langues : Anglais (eng) Mots-clés : Motor imagery  Action observation  Mu rhythm  Mirror neuron system  Autism  EEG Index. décimale : PER Périodiques Résumé : Abstract The mental simulation theory suggests activation of the motor network during imagery and observation of human movements, similarly to the activation during action execution and is proposed to be mediated by the mirror neuron system. This activation can be measured by several technologies such as electroencephalography, magnetoencephalography, functional magnetic resonance imaging and positron emission tomography. It is proposed that motor network activation and therefore increased cortical excitability of primary motor cortex occur due to premotor mirror neuron system inputs. This mechanism has been demonstrated as important for planning actions and seems relevant for anticipating others actions and for empathy establishing as well as for language development. In this review we focused on studies relative to electroencephalography data of motor neural network activation during movement observation and imagery in typical and atypical development.

Body Constraints on Motor Simulation in Autism Spectrum Disorders / Massimiliano CONSON in Journal of Autism and Developmental Disorders, 46-3 (March 2016)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 46-3 (March 2016) . - p.1051-1060 Titre : Body Constraints on Motor Simulation in Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Massimiliano CONSON, Auteur ; Antonia HAMILTON, Auteur ; Francesco BELLIS, Auteur ; Domenico ERRICO, Auteur ; Ilaria IMPROTA, Auteur ; Elisabetta MAZZARELLA, Auteur ; Luigi TROJANO, Auteur ; Alessandro FROLLI, Auteur Article en page(s) : p.1051-1060 Langues : Anglais (eng) Mots-clés : ASD  Motor simulation  Motor imagery  Proprioception  Mental transformation  Development Index. décimale : PER Périodiques Résumé : Developmental data suggested that mental simulation skills become progressively dissociated from overt motor activity across development. Thus, efficient simulation is rather independent from current sensorimotor information. Here, we tested the impact of bodily (sensorimotor) information on simulation skills of adolescents with Autism Spectrum Disorders (ASD). Typically-developing (TD) and ASD participants judged laterality of hand images while keeping one arm flexed on chest or while holding both arms extended. Both groups were able to mentally simulate actions, but this ability was constrained by body posture more in ASD than in TD adolescents. The strong impact of actual body information on motor simulation implies that simulative skills are not fully effective in ASD individuals.
