Final answer:
Classical conditioning refers to the bond or connection between stimulus and response. It involves learning to associate events or stimuli that occur together.
Step-by-step explanation:
The experienced bond or connection between stimulus and response is referred to as classical conditioning. In classical conditioning, organisms learn to associate events or stimuli that repeatedly occur together. A well-known example of classical conditioning is Ivan Pavlov's experiments with dogs, where he conditioned the dogs to associate the sound of a bell with food, resulting in salivation.
