  2. Review: Unconditioned Response (Reaction!) Unconditioned Stimulus (Something happens!)

  3. Conditioning… Unconditioned Stimulus (Something happens!) Add another stimulus! Call it Conditioned stimulus Unconditioned Response (Reaction!)

  4. If the response occurs with just the conditioned stimulus, your response becomes a conditioned response! Unconditioned Stimulus (Something happens!) X Add another stimulus! Call it Conditioned stimulus Unconditioned Response (Reaction!) conditioned Response (Reaction!)

  5. Conditioned stimulus • Anything that elicits a response not directly related to the original stimulus. • For example: can opener promotes drooling.

  6. Classical Conditioning • Take a stimulus and pair it with an unconditioned stimulus, and you can eventually get the response. • For example: • Oh, and 12 is C.

  7. Unconditioned Stimulus • Happens whether you plan for it or not. • Loud noises, bee stings, dog barking

  8. Unconditioned Response • Happens no matter what…

  9. Conditioned Response • The response that an organism does to a conditioned stimulus. • For example:

  10. Stimulus Discrimination • When a conditioned response only happens for a specific sound or pitch or day or color or dog, etc…

  11. Stimulus Generalization • When a response happens to anything close to the conditioned stimulus. • I am afraid of all flying insects after getting stung by a bee. • I am afraid of all doctors after…

  12. Extinguishing a Conditioned Response… • Repeat a conditioned stimulus without pairing it to the original stimulus.

  13. The occurrence of spontaneous recovery demonstrates that • extinction does not really result in the loss of conditioning

  14. Horror movie music, or words that elicit hunger… • Higher order conditioning.

  15. Fears, anxieties, phobias • Conditioned emotional response according to behaviorists…

  16. According to Behaviorists… • Needing more of a drug is the result of conditioning… called conditioned drug response.

  17. Reinforcer • Anything that happens after a response that either promotes or discourages the response in the future.

  18. Primary Reinforcer • A reinforcer that is innately satisfying no learning takes place to make the reinforcement pleasurable.

  19. Scolding, Nagging, Criticizing… • Negative Reinforcers

  20. Gold Stars, chocolate, smile… • Primary reinforcers

  21. Schedules of reinforcement • "Timetables" that determine when a response will be reinforced.

  22. Fixed-Ratio Schedule • Reinforces a behavior after a set number of responses.

  23. Variable-Ratio Schedule • A timetable in which responses are rewarded an average number of time, but on an unpredictable basis.

  24. Fixed-Interval Schedule • Reinforces the first appropriated response after a fixed amount of time has elapsed.

  25. Variable-Interval Schedule • A timetable in which a response is reinforced after a variable amount of time has elapsed.

  26. FFTKAT • The closer the schedule is to continuous reinforcement, the faster the individual learns. However, once behavior is learned, the intermittent schedules can be effective n maintaining behavior.
