After doing this repeatedly, the pairing of food and bell eventually established the dog's Conditioned Response of salivating to the sound of the bell. Pavlov rang the bell, then fed the dogs'. To establish if there can be salivation with the pairing of a stimulus, Pavlov decided to use the bell as the Conditioned Stimulus, so-called because it was being paired with Food (US) to elicit salivation. Pavlov noticed that sight alone of the dog's handler was enough to make the dog salivate. This theory may seem complicated, but dont worry - it will become clear.įor the sake of quality understanding, we will look at Pavlov's famous original experiments with dogs. It was this discovery gave Pavlov the Nobel Prize It was found that almost any stimulus could have the same effect of salivation if paired with the presentation of the original stimulus often enough. In being a physiologist, not a psychologist (he was very emphatic about this), Pavlov sought a scientific explanation of why dogs' will start salivating before they have seen food. Pavlov's famous Classical Conditioning experiments became one of the first learning theories and contributed to the notion of psychology as an objective science. Pavlov began to study Classical Conditioning at the age of fifty, and continued to study it for another thirty years. At forty one years of age, he was the head of the physiology department. Needless to say Darwin's beliefs did not tie in with Pavlov's religious ideas, so he abandoned them and went to the University of St Petersburg and specialized in animal physiology and medicine.Īfter achieving a medical degree he became an assistant in a St Petersburg laboratory and then went on to be appointed a professor of pharmacology. The turning point in his life came when he read the Russian translations of scientific writings which alluded to the Darwinian theory. As a result of this early religious influence, Pavlov planned to have a career in the church, a choice which his father approved as his early school performance showed no signs of brilliance. Ivan Pavlov was born in Rayazan, Central Russia, the son of a poor village priest. Web Page by: Victoria Mckay (00125652) for 175.202 Assignment 2a Be passionate in your work and in your searching.'
