Pavlov used a metronome, setting it going just before the dogs were fed (or at least, before they chewed some food before it plopped out of their neck hole). Pavlov conducted experiments on this, associating different stimulus with the presence of food. They would salivate at the site of the coated assistants alone, whether food was present or not. Pavlov noted, after the death of one particularly-hardy dog ten days after its operation, that “our passionate desire to extend experimental trials on such a rare animal was foiled by its death as a result of extended starvation and a series of wounds."ĭuring this research, Pavlov noticed that the dogs would begin to salivate whenever they saw the white lab coat of his assistant on their way to give the dogs food. In the famous experiments that Ivan Pavlov conducted with his dogs, Pavlov found that objects or events could trigger a conditioned response. They were placed on an angle so that they were facing a bowl of mince meat in front of them, which the dog would eat (before it fell out of their neck holes onto a collection plate). To make extra money, he also hired an assistant to gather up gastric juices from the " gastric juice factory": five large dogs harnessed to a crossbeam and attached to a container by a tube coming out of their fistulas. Fistulas (holes) placed further along the digestive system, attached to tubes, allowed him to collect, measure, and study the gastric juices to his heart's content.Īs an added bonus, he also gathered up gastric juices from dogs in his lab and sold it in Russia, France and Germany as a cure for indigestion. When the dogs ate, it would simply fall out of the hole and not make it to the stomach. To this end, he removed the esophagus of his lab dogs, and created a hole in their throat. Pavlov was initially interested in the effect of eating on pancreatic, gastric and salivary excretions, rather than the experiment he became forever known by. First off, Pavlov's method of measuring salivation was a lot more invasive than simply noticing Mr Floofels is drooly.
