Unlike Pavlov's dogs who stopped salivating when the bell rang, the child will continue to be afraid of these things because we are programmed to avoid things that we fear or that could harm us. Without being unconditioned to the response, the child would likely live life fearing the conditioned stimulus. Instances of classical conditioning can be observed in our daily lives. About two years ago I adopted a kitten from a local family. The kitten was an outdoor cat that was fed dry cat food by the family. When I brought the kitten home, I started feeding her a wet cat food twice a day. I opened cans with an electric can opener when I fed her, the sound always scared her. She would run and hide, and I would have to try to coax her out from under my bed, or wherever else she decided to take refuge. The electric can opener was the unconditioned stimulus (UCS) and his fear of the can opener was his natural, unconditioned response (UCR). After a few days, every time I opened his cat food, he would wait until the can opener stopped and after a minute or two he would sneak into the kitchen, once he was sure there was no danger to him.
