Ch. 7 Module 15Classical Conditioning
Turn to your partner what is the earliest memory you have of learning to do something?
What enabled you to learn what you did?
Learning
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.
Learning
Write this down
Anything in the environment that one can respond to.
Stimulus
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
Answer
Describe how an unconditioned stimulus (UCS) differs from a conditioned stimulus (CS); provide an example to show your understanding.

Remember the 5 components of classical conditioning are:
1. UCS 2. UCR 3. Neutral Stimulus 4. CS 5. CR
Classical Conditioning
What does each stand for?
1. UCS 2. UCR 3. CS 4. CR
Acronyms
1. Acquisition 2. Extinction 3. Spontaneous recovery.
Basic processes in classical conditioning
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
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
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
Answer
Identify and explain the three basic processes in classical conditioning..

Have you heard of this guy?
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.

Ivan Pavlov
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
Did you get meat powder and salivation?
Answers
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.
Did you get Tuning fork and Sound?
Last one. The conditioned response is ___, because
____ is now the response to the sound of the tuning fork.
Answers
Salivation
Answer
Answer
Describe the role Ivan Pavlov played in the study of classical conditioning (describe his classic experiment, using correct classical conditioning vocabulary).

Write Generalization – a process in which an
organism produces the same response to two similar stimuli.
Discrimination – a process in which an organism produces different responses to two similar stimuli.
Generalization and Discrimination
Read pg. 290 and 291 to see what happened to little Albert.
http://www.youtube.com/watch?v=Xt0ucxOrPQE
John Watson and Rosalie Rayner
How did Albert became afraid of the white rat.
Include the terms UCS, UCR, CS and CR.
How?
Look at pg. 291
First phase UCS- loud noise UCR – fear Neutral stimulus – rat UCS – loud noise UCR - fear
Albert continued
CS – Rat
CR – Fear
Stimulus similar to rat (rabbit, stuffy)
Conditioned fear (generalization)
Albert Second Phase
Because of the many pleasant events that may be associated with their use, old clothing often become conditioned stimuli that produce a relaxed, comforting response.
That old pair of jeans
Write John Garcia discovered that it was possible
to produce a nausea producing drug as a UCS to condition an aversion response to a particular taste. Paired with a drug that produces nausea a particular food or drink became the CS that also produced feelings of nausea.
Have you ever felt sick after eating a food and never eaten it again?
Taste Aversions
Answer Explain the role of the following in learning:
a) cognition; b) biological predispositions
