It was during this first course that he produced, in collaboration with another student, Afanasyev, Pavlov became passionately absorbed with physiology, which in fact was to remain of such fundamental importance to him throughout his life. In 1870 he enrolled in the physics and mathematics faculty to take the course in natural science. Sechenov, the father of Russian physiology, were spreading, Pavlov abandoned his religious career and decided Pisarev, the most eminent of the Russian literary critics of the 1860's and I. Inspired by the progressive ideas which D. He was educated first at the church school in Ryazan and then at the theological seminary there. Ivan Petrovich Pavlov was born on Septemat Ryazan, where his father, Peter Dmitrievich Pavlov, was a village priest. The following has been adapted from the Nobel website. Involved research in temperament, conditioning and involuntary reflex actions. Pavlov contributed to many areas of physiology, neurology and psychology. He wasĪwarded the Nobel Prize in Physiology or Medicine in 1904 for research pertaining to the digestive system. Ivan Petrovich Pavlov (Septem– February 27, 1936) was a Russian physiologist, psychologist, and physician.

Ivan Pavlov is widely known for first describing the phenomenon now known as classical conditioning in his experiments with dogs. 'For appointments in Pennsylvania please click here'

One reinforced behavior as in reinforcing steel (added more of it). Pavlov called their resultant barking and unmanageability “experimental neurosis.”įor Pavlov, reinforcement was in terms of reiteration. Naturally, if too fine of a discrimination was required, the dogs could not solve the problem. That is, subjects were able to learn to salivate in response to a particular tone but not salivate when other tones were presented. Similarly, neural physiology was assumed to explain discrimination. For Pavlov, stimulus generalization was a neurological process. That is, there was “irradition” (a spread of effect to other parts of the brain). He showed that similar stimuli to a conditioned stimulus produced similar results. Pavlov studied classical conditioning quite thoroughly. Pavlov assumed that this “spontaneous recovery” of the association was due to excitation of neural connections. Interestingly, when the conditioned stimulus was repeatedly given until no psychic secretions occurred, a period of rest was all that was needed for the conditioned response to reappear. Pavlov called the conditioned response “psychic secretion,” and explained it as being the result of higher cortical involvement. The conditioned response was weaker than the unconditioned response (i.e., less saliva) and forgettable (if repeated too often without food being presented). After sufficient pairings of the food with another, previously unused stimulus (e.g., light), the conditioned stimulus (light) could bring about a response (conditioned response). Pavlov’s classical description notes that the presence of an unconditioned stimulus (food) produces an unconditioned response (saliva of a given amount varying somewhat between trials and between dogs). Having established a reliable dependent variable, Pavlov varied one independent variable at a time and noted the results. Exploring the matter as a good physiologist would, Pavlov employed a surgical procedure which allowed him to collect and measure the amount of saliva produced by each dog. He noted that the dogs being used as subjects in his experiments salivated not only to the presence of food but to associated stimuli (sound of keeper’s bell jingling, etc.). In 1889, Pavlov’s experiments on the digestive process brought about a curious observation. After receiving his MD in 1883, he studied physiology for two years in Leipzig, Germany.

Petersburg where he studied under Ivan Schenov (who had been a student of Muller and Helmholtz). His explanations of conditioning were pure physiological but they were interpreted by Watson and others as psychological.īorn in Ryazen (central Russia), Pavlov attended the University of St. A physiologist by training and in practice, Pavlov thought psychology was a fad. Although he won a Nobel prize for his work in explaining the processes of digestion, Ivan Pavlov is best remembered for his discovery of classical conditioning.
