I need an explanation for this Psychology question to help me study.

Classical Conditioning
I want you to think back to your childhood and come up with one example of Classical Conditioning. Think about Pavlov and his dog salivating because he associated the tuning fork with food powder and draw up your own personal example of that type of learning. In your example, I want you to identify the components of Classical Conditioning or C.C. (i.e. U.S or Unconditioned Stimulus, U.R., C.S. & C.R.).
