Reading Quiz #5 Learning Classical Conditioning Notes Example Homework: NONE Unit Test #2 Returned TOMORROW

Slide 2

Acquiring new information Modifying or reinforcing existing knowledge, behaviors, skills, values, or preferences Learning does not happen all at once Ideas build upon one another http://www.youtube.com/watch?v=57e4t-fhXDs

Slide 3

IT IS NOT VOLUNTARY!! IT HAPPENS REFLEXIVELY!!!

Slide 4

Unconditioned Stimulus: anything that generates an automatic response Unconditioned Response: The automatic response to the US Tasty food Salivate Loud Noise Startled Puff of air in the eye Twitch Being dumped Sadness Stomach Flu Nausea Alluring Image Sexual Arousal

Slide 5

Neutral Stimulus: Anything to which you DONT already have a natural reaction to Doctors Office A color Computer sound Spray bottle Sound of a bell Your friends house A building

Slide 6

Acquisition: Repeated pairing of NS & UCS NS + UCS UR CS CR

Slide 7

Generalization: When other stimuli that resemble the conditioned stimulus cause a conditioned response Discrimination: The ability to differentiate between CS and similar stimuli

Slide 8

Extinction: Eliminating a Conditioned Response caused by UCS by REPEATEDLY not following CS The NS loses its predictive power!

Slide 9

Spontaneous Recovery: Re-emergence of an extinct CR after a period of time CR will be much weaker, but still present

Slide 10

Some dog owners prefer to get an invisible fence (a fence that provides a shock when dogs with shock collars cross a wire in the ground) because their neighborhood does not allow certain fences. When the dog is about 6 inches away from the wire, it hears a loud tone. If the dog continues walking after hearing the tone, it will be shocked.

Slide 16

Higher-Order Classical Conditioning Notes The Office example Operant Conditioning Homework: Reading Guide #6 + reading quiz TUESDAY

Slide 17

Using a CS as UCS to condition a new response Its like the Inception of conditioning First-Order: UCS + NS = UR NR CS CS = CR

Slide 18

Higher-Order CS CR CS = UCS UCS (old CS) + (NEW) NS UCR EventuallyNS becomes CS CS CR

Slide 19

Slide 20

IT IS VOLUNTARY!! You learn consequences that follow your behavior (GOOD OR BAD) How do CRUSH CARDS function as operant conditioning?

Slide 21

Shaping: rewarding successive behaviors to encourage more complex behaviors

Slide 22

MUST FOLLOW A BEHAVIOR! Reinforcement: Increases the frequency of behavior Punishment: Decreases the frequency of behavior How does gambling function as both reinforcement and punishment?

Slide 23

Positive: Adding something Negative: Taking away something Is receiving a speeding ticket positive or negative?

Slide 26

Response happens every time after behavior (Continuous) Response only happens some of the time (Partial/Intermittent) Response is predictable (Fixed) Response happens after the behavior occurs a specific amount of times (Fixed Ratio) Response happens after a set amount of time (Fixed Interval) Response is Unpredictable (Variable) Response happens after the behavior occurs an unpredictable amount of times (Variable Ratio) Response happens after an unpredictable amount of time. (Variable Interval)

Slide 27

Response happens after the behavior occurs a specific amount of times Examples: Push level five times: Receive a food pellet Buy four coffees: Get one free Read five books: Get a free pizza Clean three rooms: Get a 15 minutes break

Slide 28

Response happens after a set amount of time Examples: Pressing a lever: Food pellet released every 10 minutes Studying: Final exam given every end of semester Being paid every two weeks for working a job Reading a textbook: Teacher gives quiz every Tuesday

Slide 29

Response happen after the behavior occurs an unpredictable amount of times Example: Pressing a level: Unknown how many times it takes to release pellet Buying scratch off lottery tickets: Unknown how many you need to win Using slot machines: Unknown how many times it takes to pay out Calling for donations: Unknown how many calls you need to make to get a donation

Slide 30

Response happens after an unpredictable amount of time Examples: Pressing a lever: You dont know when the pellet will be released Studying: You dont know when a pop quiz will happen Fishing: You can go very long or short periods of time without catching fish Drug Use: Random drug tests by an employer

Slide 31

Latent Learning: Even without reinforcement and punishment schedules, you are still learning (create a cognitive map) Example Other examples?

Slide 32

Intrinsic Motivation: The inner desire to perform a behavior effectively for the sake of it Extrinsic Motivation: The desire to behave a certain way to receive external rewards or avoid threatened punishment

Slide 33

I remember a daily ritual that we had: I would call Pop at work to ask if I could practice with him. He would always pause a second or two, keeping me in suspense, but hed always say yesIn his own way, he was teaching me initiative. You see, he never pushed me to play. -Tiger Woods
