Write this down Learning - A relatively permanent change in
behaviour due to experience.
Classical Conditioning – a type of learning where a stimulus is gains the power to cause a response because it predicts another stimulus that already produces the response.

Write this down
Anything in the environment that one can respond to.

Look at the diagram on pg. 282
Ex. Classical conditioning led a group of dorm mates to respond to the word Flush! The same way they responded to painfully hot water in a shower from the toilet being flushed.
Flush!

Stimulus 1-calling the word flush before flushing the toilet warns that water in the shower will be scalding.
Stimulus 2 – when the toilet is flushed hot water in the shower is scalding.
Stimulus – we hear flush Response – we jump anticipating hot water.
Flush! Cont.

Stimulus -> Response Flush -> jump
Unconditioned Stimulus (UCS) – a stimulus that triggers a response automatically and reflexive.
Stimulus -> Response

Remember the 5 components of classical conditioning are:
1. UCS 2. UCR 3. Neutral Stimulus 4. CS 5. CR

Basic processes in classical conditioning
![Page 13: Classical Conditioning. Turn to your partner what is the earliest memory you have of learning to do something? What enabled you to learn what you.](https://reader030.fdocuments.net/reader030/viewer/2022013100/551b3c90550346d41a8b54bd/html5/thumbnails/13.jpg)
Write down
Occurs when a neutral stimulus is repeatedly paired with a UCS.
Ex. We acquire the CR when a stimulus the word Flush! Was repeatedly paired with the UCS of hot water.
Acquisition
![Page 14: Classical Conditioning. Turn to your partner what is the earliest memory you have of learning to do something? What enabled you to learn what you.](https://reader030.fdocuments.net/reader030/viewer/2022013100/551b3c90550346d41a8b54bd/html5/thumbnails/14.jpg)
WriteExtinction is the procedure for reversing the
learning that has taken place. It occurs when the CS looses its power to trigger a CR.
Read Recall when we want someone to acquire a CR
we repeatedly pair a neutral stimulus with the UCS. But if we want the reverse we must weaken the strength of the association between the two stimuli.
Extinction
![Page 15: Classical Conditioning. Turn to your partner what is the earliest memory you have of learning to do something? What enabled you to learn what you.](https://reader030.fdocuments.net/reader030/viewer/2022013100/551b3c90550346d41a8b54bd/html5/thumbnails/15.jpg)
Like shouting flush but never flushing the toilet. The CR is now extinct.
Extinction ex.

Write The reappearance after a rest period of an
extinguished conditioned response
Read My response to Flush was extinct, but after
a break one yell of Flush and I would jump.
Spontaneous Recovery

What did he do?
Ivan Pavlov

Won a Nobel Prize for demonstrating the procedures of classical conditioning by using meat to train a dog to salivate to the sound of a tuning fork.

Fill in the blank The unconditioned stimulus is the
_______because it produces a salivation response without prior learning.
The unconditioned response is ____ because _____ is the response to the UCS of meat powder. No learning has taken place.
Pavlov Continued

The neutral stimulus is the sound of the ____before the dog has been conditioned. The stimulus is neutral because it does not produce salivation.
The conditioned stimulus is the ____of the tuning fork after the dog has been conditioned, because the tone now produces the response of salivation.
Pavlov Cont.

____ is now the response to the sound of the tuning fork.
