Facilitating sensorimotor integration via blocked practice underpins imitation learning of atypical biological kinematics in autism spectrum disorder / Nathan C. FOSTER in Autism, 24-6 (August 2020)  

Public ISBD [article]  inAutism > 24-6 (August 2020) . - p.1494-1505 Titre : Facilitating sensorimotor integration via blocked practice underpins imitation learning of atypical biological kinematics in autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Nathan C. FOSTER, Auteur ; Simon J. BENNETT, Auteur ; Joe CAUSER, Auteur ; Digby ELLIOTT, Auteur ; Geoffrey BIRD, Auteur ; Spencer J. HAYES, Auteur Article en page(s) : p.1494-1505 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  biological motion kinematics  blocked practice  imitation  sensorimotor integration Index. décimale : PER Périodiques Résumé : Autistic people sometimes find it difficult to copy another person's movement accurately, especially if the movement is unfamiliar or novel (e.g. to use chop sticks). In this study, we found that autistic people were generally less accurate at copying a novel movement than non-autistic people. However, by making a small adjustment and asking people to copy this movement for a set number of attempts in a predictable manner, we showed that autistic people did successfully learn to copy a new movement. This is a very important finding for autistic people because rather than thinking they cannot copy new movements, all that needs to be considered is for parents/guardians, teachers and/or support workers to make a small adjustment so that learning occurs in a predictable manner for new skills to be successfully acquired through copying. The implications from this study are wide-ranging as copying (imitation) and motor learning are important developmental processes for autistic infants and children to acquire in order to interact within the world. Therefore, practising these behaviours in the most effective way can certainly help the developmental pathway.

Motor Abilities in Autism: A Review Using a Computational Context / Emma GOWEN in Journal of Autism and Developmental Disorders, 43-2 (February 2013)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 43-2 (February 2013) . - p.323-344 Titre : Motor Abilities in Autism: A Review Using a Computational Context Type de document : Texte imprimé et/ou numérique Auteurs : Emma GOWEN, Auteur ; Antonia HAMILTON, Auteur Année de publication : 2013 Article en page(s) : p.323-344 Langues : (Eng) Mots-clés : Autism  Motor control  Sensorimotor integration  Prediction  Motor learning Index. décimale : PER Périodiques Résumé : Altered motor behaviour is commonly reported in Autism Spectrum Disorder, but the aetiology remains unclear. Here, we have taken a computational approach in order to break down motor control into different components and review the functioning of each process. Our findings suggest abnormalities in two areas'poor integration of information for efficient motor planning, and increased variability in basic sensory inputs and motor outputs. In contrast, motor learning processes are relatively intact and there is inconsistent evidence for deficits in predictive control. We suggest future work on motor abilities in autism should focus on sensorimotor noise and on higher level motor planning, as these seem to have a significant role in causing motor difficulties for autistic individuals.

The Influence of Task Difficulty and Participant Age on Balance Control in ASD / Sarah A. GRAHAM in Journal of Autism and Developmental Disorders, 45-5 (May 2015)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 45-5 (May 2015) . - p.1419-1427 Titre : The Influence of Task Difficulty and Participant Age on Balance Control in ASD Type de document : Texte imprimé et/ou numérique Auteurs : Sarah A. GRAHAM, Auteur ; Angela E. ABBOTT, Auteur ; Aarti NAIR, Auteur ; Alan J. LINCOLN, Auteur ; Ralph-Axel MULLER, Auteur ; Daniel J. GOBLE, Auteur Article en page(s) : p.1419-1427 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder  Balance control  Sensorimotor integration  Postural control  Center of pressure Index. décimale : PER Périodiques Résumé : Impairments in sensorimotor integration are reported in Autism Spectrum Disorder (ASD). Poor control of balance in challenging balance tasks is one suggested manifestation of these impairments, and is potentially related to ASD symptom severity. Reported balance and symptom severity relationships disregard age as a potential covariate, however, despite its involvement in balance development. We tested balance control during increasingly difficult balance conditions in children with ASD and typically developing peers, and investigated relationships between balance control and diagnostic/symptom severity metrics for participants with ASD, including age as a covariate. Balance deficits in ASD were exacerbated by stance alterations, but were not related to symptom severity when age was considered. These findings support impaired balance in ASD, especially in challenging conditions, but question a link between balance and symptom severity.

Goal-Directed and Goal-Less Imitation in Autism Spectrum Disorder / Kelly S. WILD in Journal of Autism and Developmental Disorders, 42-8 (August 2012)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 42-8 (August 2012) . - p.1739-1749 Titre : Goal-Directed and Goal-Less Imitation in Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Kelly S.

Our results showed that a control group imitated changes in movement kinematics and increased the level that they tracked the hand with their eyes, in the goal-less compared to goal-direction condition. In contrast, the ASD group exhibited more goal-directed eye movements, and failed to modulate the observed movement kinematics successfully in either condition. These results increase the evidence for impaired goal-less imitation in ASD, and suggest that there is a reliance on goal-directed strategies for imitation in ASD, even in the absence of visual goals.
