Description

Progressive-ratio (PR) schedules permit studying food-motivated behavior.

These schedules require an increasing number of operant responses to obtain successive rewards within a session. For example, a typical PR 5 schedule requires five responses to produce the first reinforcer, and the response requirement is incremented by five each time a reinforcer is earned. The breaking point, defined as the highest ratio completed is a classical measure reflecting the efficacy or motivational strength of food, and is increased in response to food-deprivation or reward high palatability.
