Classic Conditioning
PsychSim 5: CLASSICAL CONDITIONING
Name: Section:
Date:
This activity provides a review of Pavlov’s famous experiment on the salivary response in dogs, as well as the basic processes of classical conditioning: acquisition, generalization, discrimination training, and extinction. Salivary Response
• In Pavlov’s famous experiment, what did he call the… o unconditioned stimulus (UCS)? Meat powder (a stimulus that is natural or automatic). o unconditioned response (UCR)? Saliva flow (an unlearned condition that stimulates a response). o conditioned stimulus (CS)? The bell (an association of an unconditioned stimulus comes to trigger a response). o conditioned response (CR)? The saliva produced after the bell rung (the formation of an associated response from two stimulus).
A New Salivary Response
• Pavlov demonstrated that the dog had formed a conditioned association between two events. What were those events? What did the dog actually learn?
The dog related the sound of a bell to food. Every time he had food his mouth would have an increase in the saliva. When the bell was rung the dog assumed it was time for food and his mouth would produce more saliva.
Acquisition
• In the example of a child who fears doctors, what label would you give to the painful injection?
__X___ UCS _____ UCR _____ CS _____ CR
• In the example of a child who fears doctors, what label would you give to the presence of the doctor? _____ UCS _____ UCR ___X__ CS _____ CR
Demonstrating Acquisition
• How could we demonstrate that acquisition had occurred—that is, demonstrate that the child had learned the link between the doctor and the injection?
Every time the child saw the doctor he assumed he would be getting a shot. Because of the connection, he had a fear of doctors also.
Extinction
• What is extinction? Extinction is the process of unlearning or removing a conditioned association.
• What is spontaneous recovery? Spontaneous recovery is a conditioned association is not broken but
