Ivan Petrovich Pavlov (Russian: Иван Петрович Павлов, IPA: [ɪˈvan pʲɪˈtrovʲɪtɕ ˈpavləf] ⓘ; 26 September [O.S. 14 September] 1849 – 27 February 1936) [2] was a Russian and Soviet experimental neurologist and physiologist known for his discovery of classical conditioning through his experiments with dogs.
A conditioned alimentary reflex was established to the simultaneous application of the tone of a pneumatic tuning-fork, which was considerably damped by being placed within a wooden box coated with wool, and of a visual stimulus of three electric lamps placed in front of the dog in the slightly shaded room (Pavlov 1927: 142–143 [Lecture VIII]).
Classical conditioning occurs when a conditioned stimulus (CS) is paired with an unconditioned stimulus (US). Usually, the conditioned stimulus is a neutral stimulus (e.g., the sound of a tuning fork), the unconditioned stimulus is biologically potent (e.g., the taste of food) and the unconditioned response (UR) to the unconditioned stimulus is an unlearned reflex response (e.g., salivation).
Vladimir P. Demikhov was born on July 31, 1916, [4] into a family of Russian peasants living on a small farmstead in the northern part of Russia's Volgograd region. [5] His father, Peter Yakovlevich Demikhov was killed during the Russian Civil War when Demikhov was about three years old, [1] [5] so he and his brother and sister were raised by their mother, Domnika Alexandrovna, who managed to ...
The popular experiment is known as Pavlov's dogs where food was provided to the dogs along with repeated sounds of a bell; the food, which was the initial stimulus, would cause the dog to salivate. [6] The pairing of the bell with the food resulted in the former becoming the new stimulus even after the food was excluded from the pairing. [6]
Pavlov's typology of higher nervous activity was the first systematic approach to the psychophysiology of individual differences. Ivan Pavlov's ideas of nervous system typology came from work with his dogs and his realization of individual differences. His observations of the dogs led to the idea of excitation and inhibition in the nervous ...
Ivan Pavlov (Russian: Академик Иван Павлов, romanized: Akademik Ivan Pavlov) is a 1949 Soviet biopic directed by Grigori Roshal and starring Aleksandr Borisov, Nina Alisova and Nikolai Plotnikov. The film portrays the life of the Russian scientist Ivan Pavlov (1849–1936), known for his Pavlov's dog experiments.
The orienting response is a reaction to novel or significant stimuli. In the 1950s the orienting response was studied systematically by the Russian scientist Evgeny Sokolov, who documented the phenomenon called "habituation", referring to a gradual "familiarity effect" and reduction of the orienting response with repeated stimulus presentations ...
