An examination of response variability in children with autism and the relationship to restricted repetitive behavior subtypes / Clodagh MURRAY in Research in Autism Spectrum Disorders, 11 (March 2015)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 11 (March 2015) . - p.13-19 Titre : An examination of response variability in children with autism and the relationship to restricted repetitive behavior subtypes Type de document : Texte imprimé et/ou numérique Auteurs : Clodagh MURRAY, Auteur ; Olive HEALY, Auteur Article en page(s) : p.13-19 Langues : Anglais (eng) Mots-clés : Autism  Restricted repetitive  Behaviors  Variability Index. décimale : PER Périodiques Résumé : The current study investigated response variability in children with autism and its relationship to restricted repetitive behaviors, one of the core symptoms of the disorder. The “Penny-Hiding Game” (Baron-Cohen, 1992) was used as a measure of response variability. Variability was compared for children with autism (n = 65) and typically developing children (n = 65) and patterns of response variability were categorized from least variable to most variable for both groups. For the participants with a diagnosis of autism, these patterns were examined relative to their scores on the Repetitive Behavior Scale-Revised (RBS-R; Bodfish, Symons, & Lewis, 1999). Results showed that children with autism demonstrated significantly lower variability in their responding in the “Penny-Hiding Game” than their typically developing peers. Variability was significantly negatively correlated with total RBS-R scores and with the Stereotypy subscale and the self-injurious behavior subscale, indicating that lower variability in responding was related to higher rates of these types of restricted and repetitive behaviors. No significant correlations were observed between variability and the Compulsion subscale, the Ritualistic/Sameness behaviors subscale or the Restricted Interests subscale.

Increasing response variability in children with autism spectrum disorder using lag schedules of reinforcement / Clodagh MURRAY in Research in Autism Spectrum Disorders, 7-11 (November 2013)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 7-11 (November 2013) . - p.1481-1488 Titre : Increasing response variability in children with autism spectrum disorder using lag schedules of reinforcement Type de document : Texte imprimé et/ou numérique Auteurs : Clodagh MURRAY, Auteur ; Olive HEALY, Auteur Article en page(s) : p.1481-1488 Langues : Anglais (eng) Mots-clés : Response variability  Lag schedules  Reinforcement  U-Value statistic Index. décimale : PER Périodiques Résumé : Abstract Individuals with autism spectrum disorder (ASD) often present with deficits in variability in responding across multiple repertoires. However, research to date has resulted in little empirical evaluation of remediation strategies for such deficits. We investigated the effects of lag schedules of reinforcement on response variability using a computer-based task designed for the purpose of the study. The U-value statistic was used as a measure of variability in responding to determine if increasing the lag criterion would correspondingly increase levels of variability. Participants included children with ASD (Group 1) and neurotypical children (Group 2). Results showed that U-values were higher when reinforcement was contingent on increased variability, indicating the effectiveness of higher lag values on response variability. A significant difference in response variability between groups provided evidence for the disparity in such responding in children with ASD compared to their neurotypical peers. Group 1 showed consistently lower U-values than Group 2 indicating lower response variability. However, data from this study clearly show that lag schedules of reinforcement may be employed to increase response variability in ASD.
