Further analysis of the effects of positive reinforcement on working memory in children with autism / Lisa BALTRUSCHAT in Research in Autism Spectrum Disorders, 5-2 (April-June 2011)
[article]
Titre : Further analysis of the effects of positive reinforcement on working memory in children with autism Type de document : Texte imprimé et/ou numérique Auteurs : Lisa BALTRUSCHAT, Auteur ; Marcus HASSELHORN, Auteur ; Jonathan TARBOX, Auteur ; Dennis R. DIXON, Auteur ; Adel NAJDOWSKI, Auteur ; Ryan D. MULLINS, Auteur ; Evelyn R. GOULD, Auteur Année de publication : 2011 Article en page(s) : p.855-863 Langues : Anglais (eng) Mots-clés : Autism Executive functions Working memory Positive reinforcement Central executive Index. décimale : PER Périodiques Résumé : Individuals with autism spectrum disorders (ASD) often exhibit impaired executive function (EF) performance, including difficulty with working memory (WM), in particular. While research has documented the existence of these deficits, surprisingly little research exists that evaluates potential treatment strategies for improving EF or WM. One exception is a study that used positive reinforcement to improve performance on a classical WM task, the counting span, resulting in both maintenance and generalization (Baltruschat et al., 2011). The current study is the second in a programmatic line of research on behavioral intervention for improving WM in children with autism. This study extended the use of the same procedure (positive reinforcement) to another task which is said to measure WM, a Complex Span, and included three additional children with autism. Results demonstrated significant improvements in performance for each participant, including maintenance and generalization to untrained stimuli and untrained responses. These results provide further evidence that behavioral intervention procedures may be useful for improving skills labeled as EF or WM in children with ASD.

Titre : Using Individualized Reinforcers and Hierarchical Exposure to Increase Food Flexibility in Children with Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Robert L. KOEGEL, Auteur ; Amber A. BHAROOCHA, Auteur ; Courtney B. RIBNICK, Auteur ; Ryan C. RIBNICK, Auteur ; Mario O. BUCIO, Auteur ; Rosy M. FREDEEN, Auteur ; Lynn KERN KOEGEL, Auteur Année de publication : 2012 Article en page(s) : p.1574-1581 Langues : Anglais (eng) Mots-clés : Food refusal Inflexibility Rigidity Autism Positive reinforcement Stimulus fading Index. décimale : PER Périodiques Résumé : Inflexibility is a major characteristic of autism. In the present study we addressed inflexible mealtime behaviors and collected longitudinal data across 48 foods for 3 children, ages 6.4–7.8 years, diagnosed with autism spectrum disorder, for up to 22 weeks. Participants exhibited severe challenges with adherence to an extremely restricted repertoire of foods. We employed clinical replication and multiple baseline designs across participants to assess the effects of individualized reinforcement and hierarchical exposure to increase flexibility. Results showed that following intervention, all participants expanded their food repertoire and spontaneously requested new foods during follow up/generalization. Implications for clinical practice and directions for further research are discussed.
