Turn to your partner what is the earliest memory you have of learning to do something? What enabled you to learn what you did?
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.
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.
Stimulus -> Response Flush -> jump Unconditioned Stimulus (UCS) – a stimulus that triggers a response automatically and reflexive.
Answer Describe how an unconditioned stimulus (UCS) differs from a conditioned stimulus (CS); provide an example to show your understanding.
Answer Describe how an unconditioned response (UCR) differs from a conditioned response (CR); provide an example to show your understanding.
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
What does each stand for? 1. UCS 2. UCR 3. CS 4. CR
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.
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.
Like shouting flush but never flushing the toilet. The CR is now extinct.
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.
Answer Identify and explain the three basic processes in classical conditioning..
Have you heard of this guy? What did he do?
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
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.
Did you get meat powder and salivation?
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.
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.
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.
Read pg. 290 and 291 to see what happened to little Albert. PQE PQE
How did Albert became afraid of the white rat. Include the terms UCS, UCR, CS and CR.
Look at pg. 291 First phase UCS- loud noise UCR – fear Neutral stimulus – rat UCS – loud noise UCR - fear
CS – Rat CR – Fear Stimulus similar to rat (rabbit, stuffy) Conditioned fear (generalization)
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.
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?
Answer Explain the role of the following in learning: a) cognition; b) biological predispositions
