From Action to Interaction: Exploring the Contribution of Body Motion Cues to Social Understanding in Typical Development and in Autism Spectrum Disorders / Laurie CENTELLES in Journal of Autism and Developmental Disorders, 43-5 (May 2013)
[article]
Titre : From Action to Interaction: Exploring the Contribution of Body Motion Cues to Social Understanding in Typical Development and in Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Laurie CENTELLES, Auteur ; Christine ASSAIANTE, Auteur ; Katallin ETCHEGOYHEN, Auteur ; Manuel P. BOUVARD, Auteur ; Christina SCHMITZ, Auteur Article en page(s) : p.1140-1150 Langues : Anglais (eng) Mots-clés : Point-light display Non-verbal communication Children Autism Action representation Social interaction Index. décimale : PER Périodiques Résumé : Two studies investigated whether typically developing children (TD) and children with autism spectrum disorders (ASD) were able to decide whether two characters were communicating or not on the basis of point-light displays. Point-lights portrayed actors engaged or not in a social interaction. In study 1, TD children (4–10 years old; n = 36) grasped social intentions from body language, with a notable improvement around 7/8. In study 2, children with ASD (6–12 years old; n = 12) could categorize the point-light displays at above-chance levels, but performed less efficiently, especially for the social interaction displays, than TD children (matched to chronological and non-verbal mental age, 6–12 years old; n = 24). An action representation deficit is discussed in relation to a social representation deficit and it is suggested that these deficits might be linked to altered maturational process of the mirror system in ASD.

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.

In order to clearly distinguish the specificity between the two disorders, children with autism spectrum disorder or developmental coordination disorder presenting the same degree of motor impairment, thus homogeneous profiles, were examined in a reach-to-displace paradigm, which allows the integrity of two main aspects of motor control (anticipation/feedforward control and movement correction/feedback control) to be separately interrogated. We manipulated children?s previous knowledge of the weight of the object they were to displace: when known, participants could anticipate the consequences of the weight when reaching for the object, prior to contact with it, thus allowing for feedforward control. Conversely, when unknown prior to contact, participants had to cope with the object weight in the displacing phase of the movement, and use feedback control. Results revealed a preserved feedforward control, but an impaired movement execution (atypical slowness) in children with developmental coordination disorder, while children with autism spectrum disorder displayed the opposite pattern with an impaired feedforward control, but a preserved feedback one. These findings shed light on how specific motor impairments might differently characterize developmental disorders and call for motor rehabilitation programmes adapted to each population. Lay abstract A vast majority of individuals with autism spectrum disorder experience impairments in motor skills. Those are often labelled as additional developmental coordination disorder despite the lack of studies comparing both disorders. Consequently, motor skills rehabilitation programmes in autism are often not specific but rather consist in standard programmes for developmental coordination disorder. Here, we compared motor performance in three groups of children: a control group, an autism spectrum disorder group and a developmental coordination disorder group. Despite similar level of motor skills evaluated by the standard movement assessment battery for children, in a Reach-to-Displace Task, children with autism spectrum disorder and developmental coordination disorder showed specific motor control deficits. Children with autism spectrum disorder failed to anticipate the object properties, but could correct their movement as well as typically developing children. In contrast, children with developmental coordination disorder were atypically slow, but showed a spared anticipation. Our study has important clinical implications as motor skills rehabilitations are crucial to both populations. Specifically, our findings suggest that individuals with autism spectrum disorder would benefit from therapies aiming at improving their anticipation, maybe through the support of their preserved representations and use of sensory information. Conversely, individuals with developmental coordination disorder would benefit from a focus on the use of sensory information in a timely fashion.
