Negative Punishment During Alternative Reinforcement Does Not Reduce Subsequent Resurgence, Alexander Houchins, Catherine L. Williams, Claire C. St. Peter
Negative Punishment During Alternative Reinforcement Does Not Reduce Subsequent Resurgence, Alexander Houchins, Catherine L. Williams, Claire C. St. Peter
Faculty & Staff Scholarship
Resurgence of previously suppressed behavior can occur when differential reinforcement is discontinued. Recent research has investigated strategies to mitigate resurgence, such as punishing the target response during alternative reinforcement. Loss of reinforcers contingent on the target response (response cost) does not appear to attenuate resurgence, but these effects had not been replicated with other negative-punishment procedures, such as timeout. This study investigated effects of timeout on subsequent resurgence when adults responded to earn points during a computer task. Timeout did not affect subsequent resurgence. These findings, in combination with previous research, suggest that negative punishment may not reduce the likelihood …
Behavioral Functions Of Stimuli Correlated With Transitions Between Rich And Lean Schedules Of Reinforcement, Cory Whirtley
Behavioral Functions Of Stimuli Correlated With Transitions Between Rich And Lean Schedules Of Reinforcement, Cory Whirtley
Graduate Theses, Dissertations, and Problem Reports
Disruptions in operant behavior in the form of extended pausing reliably occur when there is a discriminable transition from a relatively rich schedule of reinforcement to a relatively lean schedule (i.e., a rich-lean transition). The present experiments assessed the reinforcing and aversive functions of the stimuli correlated with the transitions between rich and lean schedules using observing and escape procedures. In both experiments, pigeons’ key pecks were reinforced with food on a compound schedule with two FR components. Completing the FR in the rich component produced a large reinforcer; completing the FR in the lean component produced a small reinforcer. …
Chlordiazepoxide Increases Risky Choice, Devin Andrew Galdieri
Chlordiazepoxide Increases Risky Choice, Devin Andrew Galdieri
Graduate Theses, Dissertations, and Problem Reports
Probability discounting is a measure of risky choice that is correlated with maladaptive behavior and psychological disorders. Benzodiazepines are a class of drug on which relatively little risky-choice research has been conducted, particularly under conditions of chronic drug exposure. Chlordiazepoxide, a standard benzodiazepine, was administered to rats that had been trained to respond on a risky-choice task in which a choice was available between a single food pellet with 100% certainty or three food pellets with probabilities of delivery that decreased across each experimental session. During baseline, responding was sensitive to the programmed contingencies and larger-reinforcer choice decreased as the …
