Lepper, Tracy L.; Petursdottir, Anna Ingeborg; Esch, Barbara E. – Journal of Applied Behavior Analysis, 2013
We evaluated the effects of operant discrimination training (ODT) on the vocalizations of 3 boys with autism. We compared ODT to a stimulus-stimulus pairing (SSP) condition and a control condition in an adapted alternating-treatments design. ODT increased the target vocalizations of all participants compared to the control condition, and its…

Grannan, Leigh; Rehfeldt, Ruth Anne – Journal of Applied Behavior Analysis, 2012
The present investigation evaluated the effectiveness of category tact and match-to-sample instruction in facilitating the emergence of intraverbal responses (i.e., naming several items belonging to a specific category) for 2 children with autism. Results demonstrated the emergence of untaught responses, suggesting an effective instructional…

Rapp, John T.; Rojas, Nairim C.; Colby-Dirksen, Amanda M.; Swanson, Greg J.; Marvin, Kendra L. – Journal of Applied Behavior Analysis, 2010
Top-ranked items were identified during 30-min free-operant preference assessments for 9 individuals. Data from each session were analyzed to identify the item (a) that was engaged with first in each session and (b) to which the most responding was allocated after 5 min, 10 min, 15 min, 20 min, and 25 min had elapsed in each session. The results…

Reed, Derek D.; Critchfield, Thomas S.; Martens, Brian K. – Journal of Applied Behavior Analysis, 2006
A mathematical model of operant choice, the generalized matching law was used to analyze play-calling data from the 2004 National Football League season. In all analyses, the relative ratio of passing to rushing plays was examined as a function of the relative ratio of reinforcement, defined as yards gained, from passing versus rushing. Different…

Berens, Nicholas M.; Hayes, Steven C. – Journal of Applied Behavior Analysis, 2007
Arbitrarily applicable derived relational responding has been argued by relational frame theorists to be a form of operant behavior. The present study examined this idea with 4 female participants, ages 4 to 5 years old, who could not perform a series of problem-solving tasks involving arbitrary more than and less than relations. In a combined…

Rehfeldt, Ruth Anne; Root, Shannon L. – Journal of Applied Behavior Analysis, 2005
This project examined whether a history of reinforced relational responding would result in derived requesting skills in 3 adults with disabilities. Participants were first taught to request preferred items using pictures; they were then taught conditional discriminations between pictures and their dictated names and between dictated names and…
