2. Operant Conditioning A type of learning in which behavior is strengthened if followed by reinforcement or diminished if followed by punishment.

3. BOO/YEAH DEMO! Reinforcement is the Yeah! Punishment is the Boo!

4. Classical v. Operant They both use acquisition, discrimination, SR, generalization and extinction. Classical Conditioning is automatic (respondent behavior). Dogs automatically salivate over meat, then bell- no thinking involved. Operant Conditioning involves behavior where one can influence their environment with behaviors which have consequences (operant behavior).

5. Is the organism learning associations between events that it doesn’t control? Is the organism learning associations between its behavior and resulting events? Classical Conditioning Operant Conditioning

6. Edward Thorndike Law of Effect: rewarded behavior is likely to recur. SR connection

7. Thorndike Instrumental Conditioning Consequence which could be +/- would shape future responses Cat Puzzle Boxes

8. B.F. Skinner

9. Shaping or Successive Approximations A procedure in Operant Conditioning in which reinforcers guide behavior closer and closer towards a goal.

10. Operant Conditioning Chamber Skinner Box Conditioning

11. Reinforcer Any event that STRENGTHENS the behavior it follows. Two Types of Reinforcement: Positive and Negative

12. Positive Reinforcement Strengthens a response by presenting a stimulus after a response.

13. Chaining Taught to perform a series of behaviors in succession in order to get a reward Ex.—My kids must shower, brush their teeth and floss, wash their face, and comb their hair before they can read books at night!

14. Negative Reinforcement Strengthens a response by reducing or removing an aversive stimulus.

15. Negative Reinforcement Escape Learning— terminate an aversive stimulus –Ex.—Kid acts bad to get kicked out of class Avoidance Learning— avoid an aversive stimulus all together –Ex.—Kid skips class to avoid teacher she does not like

16. Punishment An event that DECREASES the behavior that it follows. Does punishment work?

17. Two Types of Punishment Positive Punishment Adding something unpleasant Ex.--Spanking Negative Punishment or Omission Training Taking away something pleasant Ex.—Taking car away for bad grades

19. Primary Reinforcer An innately reinforcing stimulus

20. Conditioned (Secondary) Reinforcer A stimulus that gains it reinforcing power through its association with a primary reinforcer. Money is also a GENERALIZED REINFORCER!

21. Token Economy Giving a “token” when someone does the correct behavior. After earning so many “tokens”, the person can trade them in for a reward. Tokens would be generalized reinforcers. Ex.—Treasure Chest in Kindergarten Ex.—Reinforcement in class today!

22. Premack Principle Reinforcing properties depend on the individual. Ex.—To reinforce my son, I would take him to get Sushi, but that would be punishment for my daughter. Ex.—To reinforce my daughter, I would take her shopping, but that would be punishment for my son.

23. Do these terms apply to Operant Conditioning too? Acquisition Extinction Spontaneous Recovery Generalization Discrimination The answer is YES! They do. Work quickly in partners to explain how.

24. Reinforcement Schedules

25. Continuous Reinforcement Reinforcing the desired response every time it occurs. Quick Acquisition Quick Extinction

26. Partial Reinforcement Reinforcing a response only part of the time. The acquisition process is slower. Greater resistance to extinction.

27. Variable-ratio Schedule A schedule of reinforcement that reinforces a response after an unpredictable number of responses. Example: I give Homer a donut at random times when he says “DOH!!!”

28. Fixed-ratio Schedules A schedule that reinforces a response only after a specified number of responses. Example: I give cookie monster a cookie every FIVE times he sings “C is for cookie”.

29. Fixed-interval Schedule A schedule of reinforcement that reinforces a response only after a specified time has elapsed. Example: I give Bart a Butterfinger every ten minutes after he moons someone.

30. Variable-interval Schedule A schedule of reinforcement that reinforces a response at unpredictable time intervals. Pop Quizzes
