Editing Stimulus–response model (section)

=== Ivan Pavlov ===
[[Ivan Pavlov|Pavlov]] started studying the digestive system in dogs by performing chronic implants of fistulas in the stomach, by which he was able to show with extreme clarity that the nervous system plays a dominant role in the regulation of the digestive process. Experiments on digestion led to the development of the first experimental model of learning, in which a neutral stimulus acquires the capacity to evoke a specific response further to repeated pairing with another stimulus that evokes the response.<ref>{{Cite journal |last1=Cambiaghi |first1=Marco |last2=Sacchetti |first2=Benedetto |date=2015-06-01 |title=Ivan Petrovich Pavlov (1849–1936) |url=https://doi.org/10.1007/s00415-015-7743-2 |journal=Journal of Neurology |language=en |volume=262 |issue=6 |pages=1599–1600 |doi=10.1007/s00415-015-7743-2 |pmid=25893257 |issn=1432-1459|hdl=2318/1526427 |s2cid=22347968 |hdl-access=free }}</ref>

[[Edward Thorndike|Thorndike]], who proposed the model, believed that learning stemmed from stimulus and response.<ref>{{Cite web |date=2020-11-24 |title=Thorndike's Stimulus Response Theory of Learning (Definition + Examples) |url=https://practicalpie.com/stimulus-response-theory/ |access-date=2023-04-22 |website=Practical Psychology |language=en-US}}</ref> Pavlov popularized and revolutionized the theory though by experimenting on the dogs.
