Schedules of Reinforcement

50 Points

This badge signifies the completion of the course Schedules of Reinforcement.

This course covers the following:

  • A schedule of reinforcement is a rule that determines what conditions will earn reinforcement.
  • Continuous reinforcement and extinction are the boundaries for all other schedules of reinforcement
  • Between these are intermittent schedules of reinforcement of which there are many. The four most basic schedules are FR, FI, VR, VI.
  • FR = Reinforcement is delivered after a fixed number of responses. We use FR1 a lot in animal training. We use FR1 to shape new behaviors. It is easily extinguished.
  • FI = Reinforcement is delivered after a fixed amount of time has passed responses. We use this in animal training for some duration behaviors. Drawbacks is the predictable schedule. Increase in response or effort to get to the reinforcer near end of time requirement.
  • VR = Reinforcement is delivered after a variable number of responses. Resistant to extinction. Constant steady rates of responding. But you must be careful about ratio strain. Helping for animals with large repertoires and for which you spend a lot of time reinforcing behavior.
  • VI = Reinforcement is delivered after a variable amount of time has passed. A great schedule for duration behaviors in my experience (ultrasound, hoof trims, blood draws, etc.) Anything in which we need the animal to remain for awhile. Remember CRF (FR1) extinguishes easily! It is not exactly predictable when reinforcers will be delivered. Resistant to extinction. Constant steady rates of responding. They are super common in real life for both human and animals.
