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. …
