On the applied use of progressive-ratio schedules of reinforcement.
Examination of responding under various schedule arrangements is a core component of many analyses of operant behavior. Much of the pioneering work in applied behavior analysis was bred from laboratory research involving the exposure of nonhuman subjects to a variety of schedule arrangements. For example, Reynolds (1961) described a multiple-schedule arrangement in which one component consisted...
متن کاملProgressive-ratio schedules and applied behavior analysis.
Establishing appropriate relations between the basic and applied areas of behavior analysis has been of long and persistent interest to me (e.g., Friman & Poling, 1996; Poling, Picker, Grossett, Hall-Johnson, & Holbrook, 1981; Porritt, Van Wagner, & Poling, 2009). Therefore, I read with enthusiasm the collection of articles on progressive-ratio (PR) schedules that appeared in the Summer 2008 is...
متن کاملEffects of rimonabant on behavior maintained by progressive ratio schedules of sucrose reinforcement in obese Zucker (fa/fa) rats.
This experiment reports on the ability of rimonabant to alter the reinforcing properties of food in the genetically obese Zucker (fa/fa) rat, a strain that exhibits higher levels of endocannabinoids in brain regions that correspond to heightened food intake. We characterized food reinforcement in obese and lean Zucker rats by placing behavior under progressive ratio schedules of sucrose reinfor...
متن کاملComparison of fixed-ratio and progressive-ratio schedules of maintenance of stimulant drug-reinforced responding.
The effectiveness of doses of i.v. cocaine and nomifensine in maintaining lever-press responding in rhesus monkeys was evaluated under two schedules, fixed- and progressive-ratio (FR, PR). The doses that maintained maximum rates of responding under the fixed-ratio schedule were 0.32 mg/kg per injection cocaine and 0.10 mg/kg per injection nomifensine. The fixed-ratio rates maintained by this do...
متن کاملWhat 50 years of research tell us about pausing under ratio schedules of reinforcement.
Textbooks in learning and behavior commonly describe performance on fixed-ratio schedules as "break and run," indicating that after reinforcement subjects typically pause and then respond quickly to the next reinforcement. Performance on variable-ratio schedules, on the other hand, is described as steady and fast, with few long pauses. Beginning with Ferster and Skinner's magnum opus, Schedules...
