To test this phenomenon, Pavlov experimented by ringing a bell when the dogs were fed. If the bell was sounded in close association with their meal, the dogs learned to associate the sound of the bell ... with food. After their responses had been conditioned, the sound of the bell ringing caused the dogs to salivate. Pavlov's discovery of classical conditioning paved the way for an objective science of behavior.
