conditioned response  listen  (kun-DIH-shund reh-SPONTS)

  A type of learning in which repeated exposure to something may affect a person’s behavior when they encounter an unrelated object, sound, or smell that occurred at the same time as the initial exposure. For example, a patient who always feels sick after receiving chemotherapy in a clinic that smells a certain way may be conditioned to feel sick when smelling the same odor in a different place.
