Explain each of the following situations in terms of classical conditioning. For each description, identify the unconditioned stimulus (US), unconditioned response (UR), conditioned stimulus (CS), and conditioned response (CR). Remember, the neutral stimulus is something that does not lead to a response until after it is paired with the US – then the neutral stimulus becomes the conditioned stimulus. If you are able, explain the general principles at work (e.g. “this is an example of stimulus discrimination”). The first one is done for you. Hint: Watching the two videos on classical conditioning is highly recommended! Example: Early in their relationship, the mere sight of Chris excited Joel. This gradually died out, however, as Chris tolerated Joel but didn’t pay much attention to him. When the relationship ended, Joel was bored with Chris and didn’t even think about them for the next year. Now, he was surprised at how excited he was becoming as he saw Chris through the window of a bus. Answer: US = romantic activities UR = romantic excitement CS = Chris CR = romantic excitement Joel was attracted to Chris (previously neutral stimulus) because of things they did (US) that naturally elicited romantic excitement (UR). Just the sight of Chris (CS) then elicited romantic excitement (CR) in Joel. The response was later extinguished after Chris failed to stimulate their partner (US). The reaction one year later suggests spontaneous recovery—the reappearance of the conditioned response after an apparent extinction. Michael was sick and nauseated after going to a restaurant and eating a chicken dish. He swore that he would never eat chicken again. A few weeks later, he went to visit his mother and was looking forward to a delicious home cooked meal. As he entered the kitchen, however, Michael felt nauseated when he saw the golden-brown turkey sitting on the table.
Classical Conditioning
Instructions: Explain each of the following situations in terms of classical conditioning. For each description, identify the unconditioned stimulus (US), unconditioned response (UR), conditioned stimulus (CS), and conditioned response (CR).
Remember, the neutral stimulus is something that does not lead to a response until after it is paired with the US – then the neutral stimulus becomes the conditioned stimulus. If you are able, explain the general principles at work (e.g. “this is an example of stimulus discrimination”). The first one is done for you. Hint: Watching the two videos on classical conditioning is highly recommended!

Answer:
US = romantic activities
UR = romantic excitement
CS = Chris
CR = romantic excitement
