3. Review: Classical Conditioning
Before Conditioning:
UCS  UCR (reflex)
NS  No Response
During Conditioning:
UCS + NS  UCR
After Conditioning:
CS  CR
Before Conditioning:
Food  Salivation (reflex)
Bell  No Response
During Conditioning:
Food + Bell  Salivation
After Conditioning:
Bell  Salivation

4. Review: Classical Conditioning
Before Conditioning:
UCS  UCR (reflex)
NS  No Response
During Conditioning:
UCS + NS  UCR
After Conditioning:
CS  CR
Before Conditioning:
Altoid Mint  Recognize bad breath/take mint
Computer Noise  No Response
During Conditioning:
Altoid Mint + Computer Noise  Recognize bad breath/take mint
After Conditioning:
Computer Noise  Recognize bad breath/take mint

5. Review: Classical Conditioning
Identify the UCS, UCR, NS, CS, and CR in the following scenario.
Your significant other often yells at you and makes you feel bad. Pretty soon, you can’t stand the look of that person and end the relationship. You meet another person who looks like your ex. Although they seem nice, you find yourself feeling bad every time you are around them.

7. Learning
Operant Conditioning

8. B. F. Skinner
Operant Conditioning: Learning from consequences of behavior
How does this differ from classical conditioning?
Classical: experimenter presents the stimuli independent of the person’s behavior
Operant: person must engage in a behavior in order for the outcome to occur
(The rat must learn how to solve a problem of how to get food)

9. Reinforcement
A consequence that increases the likelihood a behavior to occur again
Positive reinforcement: Presenting something desirable; a reward
Ex: Money for good grades
Negative reinforcement: Taking away something you don’t like
Ex: Taking aspirin to get rid of a headache
Ex: Beeping when you leave the head lights on. You must turn off the lights to stop the beeping.
Examples: Social approval, money, extra privileges
What behaviors do you do to receive these reinforcement?
There are obviously reinforcers that work better than others!

10. Schedules of Reinforcement
Continuous schedule: Reinforcement given every time something occurs
Ex: Get a piece of candy every time you answer a question.
Partial schedule: Reinforcement given only sometimes (4 types)
Ex: Get a piece of candy sometimes when answer a question.
Which do you think works better?
Is behavior best maintained by reinforcing every response? Why?

11. Partial Schedules of Reinforcement
Ratio: behavior is reinforced based on the frequency of responses
(Frequency: How often something occurs)
Interval: behavior reinforced based on time

12. Partial Schedules of Reinforcement
Ratio
Examples:
Fixed-Ratio: reinforcement after a fixed # of responses
Getting paid for every 5 pizzas made
Variable-Ratio: reinforcement after a varying # of responses
Playing a slot machine
Interval
Examples:
Fixed-interval: reinforcement for response after a fixed time elapsed
Getting a paycheck every Friday
Variable-interval: reinforcement for response after random time periods
Pop quizzes

13. Punishment
Unpleasant consequence which decreases a behavior to occur again.
Examples?
Punishers and reinforcements depend on the learner!

14. Which one?
Identify if the following examples illustrate positive reinforcement, negative reinforcement, or punishment
1. The police stop drivers and give awards for safe driving.
2. The coach removes a player from a game who commits an intentional foul.
3. Taking aspirin to relieve a headache.
4. A baseball player glares at a teammate who makes an error during the game.
5. A mother gives candy to the crying child in the grocery store.
6. A hospital patient is given extra visitation time after eating a full meal.
7. A teenager is grounded until his or her homework is completed.
8. Running from a building when the fire alarm sounds.
9. A child is scolded for playing in the street.
10. A rat presses a lever to terminate a shock or loud tone.
11. Teacher gives extra credit for perfect attendance.
12. A defendant is harassed until he confesses.
13. A mother smiles when her child days, “Mama”

15. Partner Work Reinforcement Punishment

- Negative reinforcement: Taking away something you don’t like
Ex: Taking aspirin to get rid of a headache
Ex: Beeping when you leave the head lights on. You must turn off the lights to stop the beeping.
Punishment
- Unpleasant consequence which decreases a behavior to occur again.
