Ivan Petrovich Pavlov (14 September 1849 – 27 February 1936) was a Russian physiologist, psychologist, and physician.

He was awarded the Nobel Prize in Physiology or Medicine in 1904 for research about the digestive system. Pavlov is widely known for first describing classical conditioning.

The son of a priest, and a theology student, Pavlov turned to science after being influenced by progressive ideas. He took natural sciences at the University of St Petersburg, and got a doctorate in 1878.

His work

In the 1890s, Pavlov was investigating the gastric function of dogs by externalizing a salivary gland so he could collect, measure, and analyze the saliva and what response it had to food under different conditions. He noticed that the dogs tended to salivate before food was actually delivered to their mouths, and set out to investigate this "psychic secretion", as he called it. Pavlov performed and directed experiments on digestion, eventually publishing The work of the digestive glands in 1897, after 12 years of research. His experiments earned him the 1904 Nobel Prize in Physiology and Medicine.

Legacy

The concept for which Pavlov is famous is the "conditioned reflex" he developed with his assistant Ivan Tolochinov in 1901.

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 called behaviourism.

The British philosopher Bertrand Russell was an enthusiastic advocate of the importance of Pavlov's work for philosophy of mind.

Pavlov's research on conditional reflexes greatly influenced not only science, but also popular culture. The phrase "Pavlov's dog" is often used to describe someone who merely reacts to a situation rather than using critical thinking. Pavlovian conditioning was a major theme in Aldous Huxley's dystopian novel, Brave New World, and also to a large degree in Thomas Pynchon's Gravity's Rainbow.

It is popularly believed that Pavlov always signalled the food by ringing a bell. However, his writings also record the use of many stimuli, including whistles, metronomes, tuning forks, and a range of visual stimuli.
