Titre : Effect of choice of task sequence on responding Type de document : Texte imprimé et/ou numérique Auteurs : Sherry STAYER SMELTZER, Auteur ; William H. AHEARN, Auteur ; Richard B. GRAFF, Auteur ; Myrna E. LIBBY, Auteur Année de publication : 2009 Article en page(s) : p.734-742 Langues : Anglais (eng) Mots-clés : Choice-of-task On-task Problem-behavior Autism Index. décimale : PER Périodiques Résumé : Choice between alternative response options has received much attention in both basic and applied research. However, there is limited study on the effects of choice of task order on responding. This study examined the effect of choice of task order on on-task behavior, duration to complete the tasks, and problem behaviors in 2 children with autism and 1 child diagnosed with Fragile X syndrome. Low preference tasks were identified via a brief multiple-stimulus preference assessment without replacement (MSWO). These tasks were then presented to participants in a variety of conditions. Alternating treatments (with yoking) and concurrent operants phases were used to assess the effects of choice of task order. The results suggested that when given the opportunity to choose between two conditions (concurrent operants), participants preferred to choose the task order, and on-task behavior increased in 2 participants, duration to complete the tasks decreased for all participants, and rate of problem behaviors decreased to zero for 2 participants. During the concurrent operants assessment, the alternative associated with the opportunity to choose task order produced a higher percentage of on-task behavior, decreased duration to complete tasks, and decreased problem behavior.

Titre : Evaluating pictorial preference assessment: The effect of differential outcomes on preference assessment results Type de document : Texte imprimé et/ou numérique Auteurs : Mark P. GROSKREUTZ, Auteur ; Richard B. GRAFF, Auteur Année de publication : 2009 Article en page(s) : p.113-128 Langues : Anglais (eng) Mots-clés : Preference-assessment Pictorial-preference-assessment Reinforcer-assessment Index. décimale : PER Périodiques Résumé : Three formats for assessing preferences were examined, tangible, pictorial with access, and pictorial without access. Reinforcer assessments were conducted to verify reinforcer effects. Phase 1 examined the assessment formats in alternating blocks of trials. Phase 2 examined results of the entire pictorial without access condition administered first followed by the other formats. Results of Phase 1 indicate similar preference hierarchies for 4 out of 5 participants regardless of format. Phase 2 reinforcer assessment results indicate pictorial without access assessments may be accurate for some but not all participants when assessments are completed in their entirety. Results further indicate that pictorial without access assessments take the least amount of time to administer. Extension and application of these results are discussed.

Titre : Further evaluation of the effects of motivating operations on preference assessment outcomes Type de document : Texte imprimé et/ou numérique Auteurs : Nick CHAPPELL, Auteur ; William H. AHEARN, Auteur ; Richard B. GRAFF, Auteur ; Myrna E. LIBBY, Auteur Année de publication : 2009 Article en page(s) : p.660-669 Langues : Anglais (eng) Mots-clés : Preference-assessment Motivating-operations Index. décimale : PER Périodiques Résumé : The abative effects of a 10-min period of free access to a participant's most preferred edible on preference assessment outcomes was examined using a multielement design with three individuals diagnosed with autism. Four moderately preferred edible items were identified for each participant; access to these edibles was then regulated throughout the study, to control for the number of edibles consumed. Four-item paired stimulus preference assessments were then conducted, under four treatment conditions. A control condition, which involved conducting four-item paired stimulus assessments, was used to determine baseline levels of preference for each edible. Preference assessments conducted under the other three treatment conditions were preceded by a 10-min period of free access to the participant's most preferred edible. The immediate condition involved conducting preference assessments immediately following the 10-min free-access period. The 10-min delay condition and the 20-min delay condition involved conducting preference assessments following a 10-min or 20-min delay after the free access period. For two participants, 10-min of free access to a preferred edible immediately prior to a preference assessment altered the probability of selecting that stimulus, but as the delay between the free-access period and the preference assessment increased, the abative effects became less apparent. For the third participant, preference did not change when assessments were immediately conducted following the 10-min period of free access. Implications of the study are discussed.
