Frank-Crawford, Michelle A.; Borrero, John C.; Nguyen, Linda; Leon-Enriquez, Yanerys; Carreau-Webster, Abbey B.; DeLeon, Iser G. – Journal of Applied Behavior Analysis, 2012
The delivery of food contingent on 10 s of consecutive toy engagement resulted in a decrease in engagement and a corresponding increase in other responses that had been previously reinforced with food. Similar effects were not observed when tokens exchangeable for the same food were delivered, suggesting that engagement was disrupted by the…

Bancroft, Stacie L.; Bourret, Jason C. – Journal of Applied Behavior Analysis, 2008
Variable reinforcement schedules are used to arrange the availability of reinforcement following varying response ratios or intervals of time. Random reinforcement schedules are subtypes of variable reinforcement schedules that can be used to arrange the availability of reinforcement at a constant probability across number of responses or time.…

Herscovitch, Brandon; Roscoe, Eileen M.; Libby, Myrna E.; Bourret, Jason C.; Ahearn, William H. – Journal of Applied Behavior Analysis, 2009
We describe a procedure for differentiating among potential precursor responses for use in a functional analysis. Conditional probability analysis of descriptive assessment data identified three potential precursors. Results from the indirect assessment corresponded with those obtained from the descriptive assessment. The top-ranked response…
