Explaining Unintended Consequences Of Differential Reinforcement Of Alternative Behavior Procedures Using Behavioral Momentum Theory, Meghan C. Herr
Masters Theses, 2010-2019
Behavioral momentum theory is a model that aids in the explanation of why behaviors that undergo popular intervention procedures, such as differential reinforcement of alternative behavior (DRA) and noncontingent reinforcement (NCR), have been found to increase in persistence and become more resistant to change, even with a reduction in frequency. The present study utilized a multiple concurrent schedule with a boy with autism who was non-verbal to increase his usage of an augmentative communication device to appropriately request for attention. Using the device was reinforced both in a context associated with reinforcement for inappropriate requests as well as in a …
The Impact Of D-Amphetamine On Resistance To Extinction (Rte) In A Single Schedule Preparation, Stephen Howard Robertson
The Impact Of D-Amphetamine On Resistance To Extinction (Rte) In A Single Schedule Preparation, Stephen Howard Robertson
Masters Theses, 2010-2019
Some researchers have suggested that the discrepancy in findings between studies of resistance-to-extinction that use single-schedules and those that use multiple-schedules is the result of increased discriminability between training and extinction conditions in the single-schedule preparation, masking the true relation between reinforcer density and resistance to extinction. Because d-amphetamine has been shown to interfere with stimulus control in a number of preparations, the current study examined the effects of d-amphetamine on rats’ lever-pressing in the context of a single-schedule resistance-to-extinction preparation. During training, doses of d-amphetamine or vehicle were administered 15 min prior to sessions in which the delivery of …
