FREDRICK, Auteur ; Robert R. PABICO, Auteur ; Henry S. ROANE, Auteur Année de publication : 2012 Article en page(s) : p.158-167 Langues : Anglais (eng) Mots-clés : Concurrent-operant  Preference assessment  Reinforcer assessment  Single-operant Index. décimale : PER Périodiques Résumé : Highly preferred stimuli were identified via two preference assessments (based on Fisher et al., 1992), the second of which included stimuli that were ranked low in the initial preference assessment. Following the preference assessments, a subset of stimuli was evaluated as reinforcers in single- and concurrent-operant arrangements. In general, stimuli that were identified as highly preferred in the initial preference assessment functioned as more effective reinforcers. These results are discussed in terms of how the context in which stimuli are evaluated may play a role in the identification of effective positive reinforcers for individuals with autism and related developmental disabilities.

Unintentional stimulus control during the treatment of pica displayed by a young man with autism / Terry S. FALCOMATA in Research in Autism Spectrum Disorders, 1-4 (October/December 2007)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 1-4 (October/December 2007) . - p.350-359 Titre : Unintentional stimulus control during the treatment of pica displayed by a young man with autism Type de document : Texte imprimé et/ou numérique Auteurs : Terry S. FALCOMATA, Auteur ; Robert R. PABICO, Auteur ; Henry S. ROANE, Auteur Année de publication : 2007 Article en page(s) : p.350-359 Langues : Anglais (eng) Mots-clés : Autism Overselectivity Pica Stimulus-control Index. décimale : PER Périodiques Résumé : Pica is a potentially life-threatening behavior displayed by many individuals with developmental disabilities. In the present study, stimulus control procedures were examined during the treatment of pica exhibited by a 12-year-old boy with autism. First, the inhibitory effect of a treatment package was tested. Next, neutral stimuli (i.e., wristbands) were introduced and paired with the inhibitory treatment in an attempt to establish stimulus control. Stimulus control was inadvertently achieved with an alternative stimulus present in the environment (i.e., presence of the therapist) rather than the intended stimuli. Results are discussed in terms of the impact of stimulus overselectivity in the development of treatment programs for individuals with autism.
