Video Feedforward for Rapid Learning of a Picture-Based Communication System / Jemma SMITH in Journal of Autism and Developmental Disorders, 44-4 (April 2014)
[article]
Titre : Video Feedforward for Rapid Learning of a Picture-Based Communication System Type de document : Texte imprimé et/ou numérique Auteurs : Jemma SMITH, Auteur ; Linda HAND, Auteur ; Peter W. DOWRICK, Auteur Année de publication : 2014 Article en page(s) : p.926-936 Langues : Anglais (eng) Mots-clés : Communication systems Rapid learning VSM Self modeling Feedforward Autism Down syndrome Index. décimale : PER Périodiques Résumé : This study examined the efficacy of video self modeling (VSM) using feedforward, to teach various goals of a picture exchange communication system (PECS). The participants were two boys with autism and one man with Down syndrome. All three participants were non-verbal with no current functional system of communication; the two children had long histories of PECS failure. A series of replications, with different length baselines, was used to examine whether video self modeling could replace the PECS method of teaching to achieve the same goals. All three participants showed rapid learning of their target behavior when introduced to their self modeling videos, and effects generalized without the need for further intervention. We conclude that VSM, using feedforward, can provide a fast, simple way of teaching the use of a picture-based communication system without the need for prompts or intensive operant conditioning. VSM may provide an accessible, easy-to-use alternative to common methods of teaching augmentative and alternative communication systems.

Titre : Three-Dimensional Kinematic Analysis of Prehension Movements in Young Children with Autism Spectrum Disorder: New Insights on Motor Impairment Type de document : Texte imprimé et/ou numérique Auteurs : Giovanna Cristina CAMPIONE, Auteur ; Caterina PIAZZA, Auteur ; Laura VILLA, Auteur ; Massimo MOLTENI, Auteur Article en page(s) : p.1985-1999 Langues : Anglais (eng) Mots-clés : Grasping Reaching Kinematics Feedforward Sensory-control-feedback Autism-spectrum-disorder Index. décimale : PER Périodiques Résumé : The study was aimed at better clarifying whether action execution impairment in autism depends mainly on disruptions either in feedforward mechanisms or in feedback-based control processes supporting motor execution. To this purpose, we analyzed prehension movement kinematics in 4- and 5-year-old children with autism and in peers with typical development. Statistical analysis showed that the kinematics of the grasp component was spared in autism, whereas early kinematics of the reach component was atypical. We discussed this evidence as suggesting impairment in the feedforward processes involved in action execution, whereas impairment in feedback-based control processes remained unclear. We proposed that certain motor abilities are available in autism, and children may use them differently as a function of motor context complexity.
