1849

• September 14, 1849

– Born in Ryazan, Russia – Father was a town Priest

1860

• Began school at age 11

– Because of a childhood accident Pavlov was forced to begin school late.

– He attended church school and seminary school.

1860 Continued

– His accident and related time in the care of doctors may have sparked his interest in medicine.

– He read Charles Darwin’s The Origin of the Species and decided that he was more interested in science than seminary.

1870

• Left seminary to study science at the University of St. Petersburg until graduation in 1875.

1870 Continued

– His scientific study in physiology led him to the discovery and study of conditioned response.

1875

• Began graduate work at the Military Medical academy.

PERSONAL LIFE

1881

• Married pedagogical student, Sara, who was devoted to his comfort and his work. Pavlov attributed his work to her.

1881 Continued

– Had he not married his wife, he might not have continued his research without her support.

Contributions to Science

1883

• Received doctorate. Finished dynamic nerves of the heart.

1890

• Professor of Physiology at the University of St. Petersburg Institute of Experimental Medicine.

– Being employed by this research institute allowed Pavlov access to funds and the time to complete his research.

1897

• Published Lectures on the function of the principle digestive glands.

1903

• Published Conditioned Reflexes

– Studying digestive physiology led Pavlov down and “accidental” path which allowed him to contribute to the study of psychology.

– He studied digestion in dogs and linked salivation to the nervous system.

– He discovered that without salivation, digestion did not take place.

1903 Continued

– His digestive experiments led him to the study of conditioned reflexes. He rang a bell, fed the dogs, rang a bell, fed the dogs and so on.

– Then he rang the bell and watched as salivation would occur.

– This provided the impact of conditioned reflexes.

1903 Continued

• An illustration of how conditioned reflexes works:

1903 Continued

– Pavlov also studied repression of this impact in that he would ring the bell and give no food and eventually the dogs considered the bell a wrong stimulus and the response was repressed.

Taking Over where Pavlov Left off

• Pavlov’s work inspired the work of John Watson and he applied it to the Behaviorist Theory in 1913. In this way, Pavlov’s work was continually studied and added to.

1904• Received Nobel Prize for

physiological and medical research, The Centrifugal Nerves of the Heart.– Pavlov was the first Russian and

physiologist to receive the Nobel Peace Prize.

1924

• Resigned from St. Petersburg Institute of Experimental Medicine

1935

• His youngest son died.

– The death of his son probably played a role in his own death a year later, but that is not a known fact.

1935 Continued

• The government built a laboratory for his work on conditioned reflexes.

1935 Continued– The laboratory built for him validated

his efforts and encouraged further study.

Pavlov’s Work Continues

• Further study continues today on Pavlov’s Theory of Conditioned Reflexes. – This would be his greatest contribution to

human learning.– His techniques have been modified and are

used today to treat humans in anti-phobia therapy.

– Patients are taught to relax and then use the relaxation technique while being exposed to the phobia.

– Commercials can be attributed in part to Pavlov, at least how they are to function can be. We see the messages, associate them with the product, then think we need the product.

1936

• February 27 – Ivan Pavlov died of liver cancer in Leningrad at the age of 87.

• Pavlov proclaimed himself to be a physiologist, not a psychologist.
