Research suggests that
development of ANV involves the elements of classic conditioning.
Classical conditioning is also known as Pavlovian conditioning
after the Russian scientist who was able to induce dogs to salivate
at the sound of a bell that had been repeatedly paired with the
ingestion of food. This paradigm applies to chemotherapy in a similar
way.
