Patty goes to a pizza buffet, afterwards she comes down with a horrible rash. She visits her doctor who assures her that the rash resulted from overexposure to the sun on the beach that day. After that experience at the buffet, Patty decides never again to eat pizza, her most loved "food group". In Patty's case, pizza has become a/an:

A. Unconditional response
B. Unconditional stimulus
C. Conditioned response
D. Conditioned stimulus

I chose answer D conditioned stimulus

Yes!

I also chose D

You are correct! In Patty's case, where she developed a rash from eating pizza at the buffet, pizza has become a conditioned stimulus.

To understand why, let's break down the different components of classical conditioning:

1. Unconditional Stimulus (UCS): A stimulus that naturally and automatically triggers a response. In this case, the UCS would be the sun's rays that caused Patty to develop a rash.

2. Unconditional Response (UCR): The automatic and natural response that occurs as a result of the UCS. In this case, the UCR would be the rash on Patty's skin.

3. Conditioned Stimulus (CS): A previously neutral stimulus that, after being paired with the UCS, triggers a conditioned response. In this case, pizza is the CS because it initially had no effect on Patty's rash, but after being associated with the buffet experience, it started triggering a reaction.

4. Conditioned Response (CR): The learned response that occurs in response to the conditioned stimulus. In this case, Patty's decision to never eat pizza again is an example of a conditioned response. She associated the pizza with the buffet experience and the resulting rash, which made her develop a negative attitude towards pizza.

Therefore, the correct answer is D. Conditioned stimulus.
