Agenda – Wednesday, February 19th

  • Reading Quiz #5 – Learning

  • Classical Conditioning

    • Notes

    • Example

  • Homework: NONE

    • Unit Test #2 – Returned TOMORROW


Learning unit

Learning Unit

  • 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

Classical conditioning

Classical Conditioning

IT IS NOT VOLUNTARY!!

IT HAPPENS REFLEXIVELY!!!


Classical conditioning1

Classical Conditioning

  • 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


Classical conditioning2

Classical Conditioning

  • Neutral Stimulus: Anything to which you DON’T already have a natural reaction to

    • Doctor’s Office

    • A color

    • Computer sound

    • Spray bottle

    • Sound of a bell

    • Your friend’s house

    • A building


Classical conditioning3

Classical Conditioning

Acquisition: Repeated pairing of NS & UCS

NS + UCS  UR

CS  CR


Classical conditioning4

Classical Conditioning

Generalization: When other stimuli that resemble the conditioned stimulus cause a conditioned response

Discrimination: The ability to differentiate between CS and similar stimuli


Classical conditioning5

Classical Conditioning

  • Extinction: Eliminating a Conditioned Response

    • caused by UCS by REPEATEDLY not following CS

    • The NS loses its predictive power!


Classical conditioning6

Classical Conditioning

  • Spontaneous Recovery: Re-emergence of an extinct CR after a period of time

    • CR will be much weaker, but still present


Example invisible fences

Example: Invisible Fences

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.

Agenda friday february 21 st

Agenda – Friday, February 21st

  • Higher-Order Classical Conditioning

    • Notes

    • “The Office” example

  • Operant Conditioning

  • Homework: Reading Guide #6 + reading quiz  TUESDAY


Higher order conditioning

Higher-Order Conditioning

  • Using a CS as UCS to condition a new response

  • It’s like the “Inception” of conditioning

  • First-Order:

    • UCS + NS = UR

    • NR  CS

    • CS = CR


Higher order conditioning1

Higher-Order Conditioning

  • Higher-Order

    • CS  CR

    • CS = UCS

    • UCS (old CS) + (NEW) NS  UCR

    • Eventually…NS becomes CS

    • CS  CR


The office higher order

The Office – Higher Order?


Operant conditioning

Operant Conditioning

IT IS VOLUNTARY!!

You learn consequences that follow your behavior (GOOD OR BAD)

How do CRUSH CARDS function as operant conditioning?


Operant conditioning1

Operant Conditioning

Shaping: rewarding successive behaviors to encourage more complex behaviors


Operant conditioning2

Operant Conditioning

How does gambling function as both reinforcement and punishment?

MUST FOLLOW A BEHAVIOR!

Reinforcement: Increases the frequency of behavior

Punishment: Decreases the frequency of behavior


Operant conditioning3

Operant Conditioning

Is receiving a speeding ticket positive or negative?

Positive: Adding something

Negative: Taking away something

Agenda – Monday, February 24th

  • Important people (yellow sheet)

    • Reading Quiz #6 tomorrow


Important people

Important People

Ivan Pavlov

B.F. Skinner

John B. Watson

Edward Thorndike

Albert Bandura


Reinforcement schedules

Reinforcement Schedules


Fixed ratio

Fixed Ratio

  • 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


Fixed interval

Fixed Interval

  • 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


Variable ratio

Variable Ratio

  • 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


Variable interval

Variable Interval

  • Response happens after an unpredictable amount of time

  • Examples:

    • Pressing a lever: You don’t know when the pellet will be released

    • Studying: You don’t 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


Cognition

Cognition

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

Example 

Other examples?


Cognition1

Cognition

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


Intrinsic or extrinsic

Intrinsic or Extrinsic?

  • “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 he’d always say yes…In his own way, he was teaching me initiative. You see, he never pushed me to play.”

    • -Tiger Woods
