  1. Schedules of Reinforcement Chapter 6 Learning and Behavior (Chance)

  2. Chapter Questions • What is a schedule of reinforcement? • What are the four basic kinds of intermittent schedules? • What sort of reinforcement schedule would make behavior most persistent? • What is “stretching the ratio,” and how do you do it? • What do you call a schedule in which a behavior is never reinforced? • What is a multiple schedule? • What is the matching law, and what does it have to do with making choices? • Why are reinforcement schedules important?

  3. Today’s Guiding Questions • What is a schedule of reinforcement? • What are the four basic intermittent schedules? • What is “stretching the ratio,” and how do you do it? • What sort of reinforcement schedule would make behavior most persistent? • Why are reinforcement schedules important? • What is the matching law?

  4. What is a schedule of reinforcement? • Schedule of reinforcement • Continuous reinforcement (CRF)

  5. 4 Simple Intermittent Schedules of Reinforcement

  6. Fixed Ratio (FR) Schedules

  7. Variable Ratio (VR) Schedules

  8. Fixed Interval (FI) Schedules

  9. Variable Interval (VI) Schedules

  10. Other Simple Schedules • Fixed duration (FD) schedule • Variable duration (VD) schedule • Differential reinforcement of low rate (DRL) • Differential reinforcement of high rate (DHL) • Noncontingent reinforcement (NCR) • Fixed time (FT) schedule • Variable time (VT) schedule

  11. Complex Schedules • Multiple schedule • Mixed schedule • Chain schedule • Tandem schedule • Cooperative schedule • Concurrent schedule

  12. Extinction

  13. Why are some behaviors more resistant to extinction? • Partial reinforcement effect (PRE)

  14. Why does the PRE exist? • According to the discrimination hypothesis…

  15. According to the frustration hypothesis…

  16. According to the sequential hypothesis…

  17. According to the response unit hypothesis…

  18. What is the matching law?
