Ivan Petrovich Pavlov (Russian: Иван Петрович Павлов, September 14, 1849 – February 27, 1936) was a Russian physiologist, psychologist, and physician. He was awarded the Nobel Prize in Physiology or Medicine in 1904 for research pertaining to the digestive system. Pavlov is widely known for first describing the phenomenon now known as classical conditioning in his experiments with dogs.

Life and research
Pavlov contributed to many areas of physiology, neurology and psychology. Most of his work involved research in temperament, conditioning and involuntary reflex actions.
Pavlov performed and directed experiments on digestion which earned him the 1904 Nobel Prize in Physiology and Medicine
Carl Jung continued Pavlov's work on TMI and correlated the observed shutdown types in animals with his own introverted and extroverted temperament types in humans. Introverted persons, he believed, were more sensitive to stimuli and reached a TMI state earlier than their extroverted counterparts. This continuing research branch is gaining the name highly sensitive persons.
William Sargant and others continued the behavioral research in mental conditioning to achieve memory implantation and brainwashing.
