1 Classical Conditioning

2  Turn to your partner what is the earliest memory you have of learning to do something?  What enabled you to learn what you did?

3  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.

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

5  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.

6  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.

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

8  Answer  Describe how an unconditioned stimulus (UCS) differs from a conditioned stimulus (CS); provide an example to show your understanding.

9  Answer  Describe how an unconditioned response (UCR) differs from a conditioned response (CR); provide an example to show your understanding.

10  Share your examples with your partner  Remember the 5 components of classical conditioning are:  1. UCS  2. UCR  3. Neutral Stimulus  4. CS  5. CR

11  What does each stand for?  1. UCS  2. UCR  3. CS  4. CR

12  1. Acquisition  2. Extinction  3. Spontaneous recovery.

13  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.

14  Write Extinction 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.

15  Like shouting flush but never flushing the toilet. The CR is now extinct.

16  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.

17  Answer  Identify and explain the three basic processes in classical conditioning..

18  Have you heard of this guy?  What did he do?

19  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.  xuzI xuzI 

20  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.

21  Did you get meat powder and salivation?

22  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.

23  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.

24  Salivation

25  Answer  Describe the role Ivan Pavlov played in the study of classical conditioning (describe his classic experiment, using correct classical conditioning vocabulary).

26  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.

27  Read pg. 290 and 291 to see what happened to little Albert.  PQE PQE

28  How did Albert became afraid of the white rat.  Include the terms UCS, UCR, CS and CR.

29  Look at pg. 291  First phase  UCS- loud noise  UCR – fear  Neutral stimulus – rat  UCS – loud noise  UCR - fear

30  CS – Rat  CR – Fear  Stimulus similar to rat (rabbit, stuffy)  Conditioned fear (generalization)

31  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.

32  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?

33  Answer  Explain the role of the following in learning: a) cognition; b) biological predispositions

34  Multiple choice  1-C, 2-B, 3-A, 4-A, 5-D, 6-A  Matching  A-11, B-6, C-4,D-2, E-3, F-5, G-1, H-9, I- 12, J-7.  Fill in the blank  8. unconditioned stimulus, unconditioned response, conditioned stimulus, conditioned response, neutral stimulus. 9. acquisition, extinction, spontaneous recovery. 10. Ivan Pavlov
