![]() ![]() ![]() (i.e., a stimulus-response connection that required no learning). In behaviorist terms, food is an unconditioned stimulusĪnd salivation is an unconditioned response. This reflex is ‘hard-wired’ into the dog. ![]() For example, dogs don’t learn to salivate whenever they see food. Pavlov (1902) started from the idea that there are some things that a dog does not need to learn. Accordingly, he devoted the rest of his career to studying this type of learning. When Pavlov discovered that any object or event which the dogs learned to associate with food (such as the lab assistant) would trigger the same response, he realized that he had made an important scientific discovery. Pavlov predicted the dogs would salivate in response to the food placed in front of them, but he noticed that his dogs would begin to salivate whenever they heard the footsteps of his assistant who was bringing them the food. He inserted a small test tube into the cheek of each dog to measure saliva when the dogs were fed (with a powder made from meat). Ivan Petrovich Pavlov (1849–1936) was aĭuring the 1890s, Russian physiologist, Ivan Pavlov was researching salivation in dogs in response to being fed. Like many great scientific advances, Pavlovian conditioning (aka classical conditioning) was discovered accidentally. Pavlov’s Dogs Study and Pavlovian Conditioning Explained ![]()
