4. Background Information
Born: September 14, 1849
Birthplace: Ryazan, Russia
Education: Attended Ryazan Ecclesiastical Seminary
for several years, dropped out and enrolled at the
University of St. Petersburg. Earned his doctorate
(equivalent to a Bachelor's Degree) in 1879
Death: February 27, 1936
5. As a child Pavlov loved to garden, to ride his bicycle, row, swim and
play gorodki.
Ivan Pavlov began his higher education at the Ryazan Church School at the
age of 11.
In 1870, Pavlov left for St. Petersburg without finishing the seminary. He
enrolled in the physics and math department, taking the natural science
course.
In his fourth year at the university, he made his first research and won a
gold medal. his research concerned the physiology of the nerves of the
pancreas.
In 1878, Professor S.P. Botkin, a famous Russian clinician, invited the gifted
young physiologist to work in the physiological laboratory at his clinic as its
chief.
In 1879 Pavlov graduated from the Medical Military Academy with an
award of a gold medal for his research work. After a competitive
examination, Pavlov won a fellowship at the Academy for postgraduate work.
6. The Beginning....
Pavlov was planning to study saliva (which he received
from dogs), collect normal data and see the reaction it
had on certain foods.
While attempting to collect saliva from dogs he noticed
that the dogs tended to pro
He called this phenomenon “psychic secretion"
His attention then turned from saliva to behaviorism.
7. Ivan Pavlov discovered Classical conditioning.
Ivan Pavlov wrote two books;
Lectures on the Work of the Digestive Glands (1897)
Conditioned Reflexes: An Investigation of the
Physiological Activity of the Cerebral Cortex (1927)
8. His Experiments…
Pavlov determined to discover
the roots of this phenomenon.
He did series of experiments
where he rang a bell just
before he served the dog food
He called these reflex
produced by the stimulus (in
this case the bell and food
served afterward) “conditional
reflexes”.
9. Conditional Reflexes
Once satisfied with his experiments,
Pavlov establish the basic rules of
“conditional reflexes”
He stated that conditional reflexes can
only occur when responses become
automatic after several experiences
where the condition (Pavlov's case was
the bell) occurs
Even after Pavlov's discovery his
experiments and findings wouldn't be
published in English until 1927

11. The Experiment of his death...?
On the day of his death, Pavlov asked
one of his students to stay by his bed
side and record the conditions of his
death
It's believe Pavlov wanted to create
evidence of particular experiences in
one's last moments in life
It takes a great scientist to want to
increase their knowledge on their
death bed.
12. It's almost incredible to believe he was son of a
village priest and who's mother was daughter of a priest.
He seemed destined to end up preaching just as his
father, but out came this great man who studied
extensively the digestive system of both humans and
animals and deserve the recognition he's received.
Through Pavlov's extensive research and
experiments he managed to win himself the 1904 Nobel
Prize in Physiology and Medicine for successfully
extracting digestive organs out of animals.
A great man was he who spoke these words “Don't
become a mere recorder of facts, but try to penetrate
the mystery of their origin.”
