Classical conditioning.

When my cat was a kitten, and I first got her, she was an indoor cat. Eventually, she decided she wanted to go outside a lot and would get dirty. I had to start bathing her because she would get dirty and smelly. The first time I washed her, I turned on the water and placed her inside the tub. She had started meowing loudly. The next time I turned on the water and put her in the bath, she started meowing loudly, scratching, and grabbing to get out. The third time I tried to bathe her, as soon as she heard the water running in the bathtub, she knew she was getting a bath and ran away. Whenever she hears the water running into the bathtub, she assumes she will get a bath and tries to run away.

Description of classical conditioning scenario from everyday life:

Unconditioned stimulus (UCS): The water running from the facet into the bathtub.

Unconditioned response (UCR):The fear of getting a bath and getting wet.

Neutral stimulus (NS)/Conditioned stimulus (CS): The bathtub

Conditioned response (CR): The water running into the bathtub means she is getting a bath.
