Ivan Pavlov: Works
built 804 days ago
After graduating, Pavlov entered the third course of the Medico-Chirurgical Academy (renamed in 1881 the Military Medical Academy), working as a laboratory assistant (1876-1878). In 1877 he published his first work, Experimental Data Concerning the Accommodating Mechanism of the Blood Vessels, dealing with the reflex regulation of the circulation of blood. Two years later he completed his course at the academy, and on the basis of a competitive examination he was awarded a scholarship for postgraduate study at the academy.

[I]n 1869 Pavlov enrolled into the Saint-Petersburg University and after graduating from it in 1875, enrolled at the third course of the Medical Surgical Academy ( now Medical Military Academy). After graduating in 1879 with the golden award, Pavlov started his work in the physiological laboratory of Botkin's clinic, where he carried out the investigations in blood circulation and prepared the thesis "Centrifugal nerves of the heart".

Pavlov's endeavor to give the conditioned reflex widest application in animal and human behavior tended to color his philosophical view of psychology. Although he did not go so far as to deny psychology the right to exist, in his own work and in his demands upon his collaborators he insisted that the language of physiology be employed exclusively to describe psychic activity. Ultimately he envisioned a time when psychology would be completely subsumed into physiology. Respecting the Cartesian duality of mind and matter, Pavlov saw no need for it inasmuch as he believed all mental processes can be explained physiologically.

During the years 1890-1900 especially, and to a lesser extent until about 1930, Pavlov studied the secretory activity of digestion. While working with Heidenhain, he had devised an operation to prepare a miniature stomach, or pouch; he isolated the stomach from ingested foods, while preserving its vagal nerve supply. The surgical procedure enabled him to study the gastrointestinal secretions in a normal animal over its life span. This work culminated in his book Lectures on the Work of the Digestive Glands in 1897.

Pavlov's term "conditional reflex" ("условный рефлекс") was mistranslated from the Russian as "conditioned reflex", and other scientists reading his work concluded that since such reflexes were conditioned, they must be produced by a process called conditioning. As Pavlov's work became known in the West, particularly through the writings of John B. Watson, the idea of "conditioning" as an automatic form of learning became a key concept in the developing specialism of comparative psychology, and the general approach to psychology that underlay it, behaviorism. The British philosopher Bertrand Russell was an enthusiastic advocate of the importance of Pavlov's work for philosophy of mind.

Pavlov was a dexterous operator who was compulsive about his working hours and habits. He would sit down to lunch at exactly 12 o'clock, he would go to bed at exactly the same time each evening, would always feed his dogs at exactly the same time each night and he would always leave Leningrad for Estonia on vacation on the same day each year. This behavior changed when his son Victor died in the White Army — after which he suffered from insomnia.
