WebMar 1, 2024 · The breakpoint (BP) of the progressive ratio (PR) schedule of drug delivery is a commonly used estimate of the drug abuse liability and is interpreted as a measure of … WebIn another task, the progressive ratio (PR) schedule of reinforcement can quantify perceived outcome value using instrumental response requirements that progressively increase with each reinforcer deliv- ery (Hodos 1961). In this case, the highest response/reinforcer ratio—the “breakpoint ratio”—can serve as an indicator of per- ceived “value.”
WebSessions terminate following a pause of a predetermined duration (Hodos, 1961, Jarmolowicz and Lattal, 2010). The highest completed ratio prior to session termination, called the breakpoint (BP), is often seen as a somewhat response-rate independent measure of reinforcer effects (Stafford et al., 1998). WebAnimal behavior processes. Pigeons' pecks produced grain under progressive ratio (PR) schedules, whose response requirements increased systematically within sessions. Experiment 1 compared arithmetic (AP) and geometric (GP) progressions. Response rates increased as a function of the component ratio requirement, then decreased linearly (AP) …
