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.
The best-known and most thorough early work on classical conditioning was done by Ivan Pavlov, although Edwin Twitmyer published some related findings a year earlier. [10] During his research on the physiology of digestion in dogs, Pavlov developed a procedure that enabled him to study the digestive processes of animals over long periods of ...
Watson followed the procedures which Ivan Pavlov had used in his experiments with dogs. [5] Before the experiment, Albert was given a battery of baseline emotional tests: the infant was exposed, briefly and for the first time, to a white rat, a rabbit, a dog, a monkey, masks (with and without hair), cotton, wool, burning newspapers, and other ...
One of Pavlov’s dogs with a saliva-catch container and tube surgically implanted in its muzzle, Pavlov Museum, 2005. The history of animal testing goes back to the writings of the Ancient Greeks in the 4th and 3rd centuries BCE, with Aristotle (384–322 BCE) and Erasistratus (304–258 BCE) one of the first documented to perform experiments on nonhuman animals.

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 ...

Lazaro Spallanzani (Italian, 1729–1799) performed artificial fertilization in the frog, silkmoth and dog. He concluded from filtration experiments that spermatozoa were necessary for fertilization. In 1783 he showed that human digestion was a chemical process since gastric juices in and outside the body liquefied food (meat). He used himself ...
The year 1909 saw the first English-language account of Ivan Pavlov's studies of conditioning in dogs (Yerkes & Morgulis, 1909, Psychological Bulletin). A third factor was the rise of Watson to a position of significant power within the psychological community. In 1908, Watson was offered a junior position at Johns Hopkins by James Mark Baldwin.
