Effect of Observing-Response Procedures on Overselectivity in Individuals With Autism Spectrum Disorders / Phil REED in Focus on Autism and Other Developmental Disabilities, 27-4 (December 2012)

Stimulus overselectivity can be reduced for some individuals with learning disabilities, if they engage in an observing response in which they point to, touch, or name each of the stimuli prior to selecting the one requested. To see whether this would apply to another population, a total of 55 participants with autism spectrum disorders (ASD) were trained on match-to-sample (MTS), or simple discrimination tasks, to determine whether overselectivity could be eliminated by using an observing response. MTS tasks were presented in a table-top format as well as on a computer. The observing-response procedure did not eliminate overselectivity for any of the participants, regardless of age, task, or format of presentation. These results are interpreted to call to question the effectiveness of this procedure in this context for individuals with ASD.

Extinction of Over-selected Stimuli Causes Emergence of Under-selected Cues in Higher-functioning Children with Autistic Spectrum Disorders / Phil REED in Journal of Autism and Developmental Disorders, 39-2 (February 2009)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 39-2 (February 2009) . - p.290-298 Titre : Extinction of Over-selected Stimuli Causes Emergence of Under-selected Cues in Higher-functioning Children with Autistic Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Phil REED, Auteur ; Louise MCHUGH, Auteur ; Geraldine LEADER, Auteur ; Laura BROOMFIELD, Auteur ; Aisling MCCAUSLAND, Auteur Année de publication : 2009 Article en page(s) : p.290-298 Langues : Anglais (eng) Mots-clés : Over-selectivity Behavioral-control Extinction Comparator-deficit Attentional-deficit Index. décimale : PER Périodiques Résumé : Two experiments examined whether over-selectivity is the product of a post-acquisition performance deficit, rather than an attention problem. In both experiments, children with Autistic Spectrum Disorder were presented with a trial-and-error discrimination task using two, two-element stimuli and over-selected in both studies. After behavioral control by the previously over-selected stimulus was extinguished, behavioral control by the previously under-selected cue emerged without direct training. However, this effect was only found in higher-functioning children, and not with more severely impaired children. These findings suggest that over-selectivity is not simply due to a failure to attend to all of the stimuli presented. They also suggest that extinction of over-selected stimuli may be a fruitful line of intervention for clinical intervention for some individuals.
