Classical Conditioning: Alice's dog is very anxious around cats; every time he sees one he whines. Alice began taking her dog for a walk every morning and passed the neighbor's house with cats that perched themselves on the windowsill. Her dog would whine until the cats were out of sight. Eventually, the cats disappeared from the windowsill; however, her dog continued to whine whenever he saw the neighbor's house.
In this example, what is the unconditioned stimulus (US), unconditioned response (UR), neutral stimulus (NS), conditioned stimulus (CS), and conditioned response (CR)?
