Pavlov realized that the conditioned reflex method has a limitation it cannot be used in the study of human subjects because their thinking interferes with experimental results. Pavlov’s famous experiment of the drooling dog shows that there are two types of reflexes: innate reflexes that are evoked by the irritant itself and acquired reflexes that are evoked by subsequent associations. He trained dogs to salivate at the sound of a bell. Pavlov noticed that sight alone of the dog's handler was enough to make the dog salivate. Most of what we believe we know about Ivan Pavlov (18491936), the iconic Russian physiologist, is wrong. For the sake of quality understanding, we will look at Pavlov's famous original experiments with dogs. This theory may seem complicated, but dont worry - it will become clear. The dogs used in conditioned response experiments by a Russian scientist of the late nineteenth century, Ivan Pavlov. During the next decades, Pavlov provided reasons for this decision: The physiological approach (a) avoids anthropomorphizing or speculations about the dogs' subjective experiences, and (b) permits the explanation of observed phenomena which the subjective method is not capable of doing. It was this discovery gave Pavlov the Nobel Prize in 1904. Snarskiy, Pavlov chose the first alternative. In 1901, after a bitter conflict with his disciple A. They didn’t need to see, let alone taste. To account for conditioned reflex phenomena, Pavlov faced two alternatives: to offer an objective (physiological) or a subjective (psychological) explanation. Pavlov had noticed, in his research on the digestive system of dogs, that they drooled as soon as they saw the white lab coats of the people who fed them. As you can imagine, every time the lab assistant came out with food, the dogs would start to salivatenothing fancy. The salivation was measured with a device attached to the dog’s mouth. The salivary reflex, according to Pavlov, was of minor biological significance but a good indicator of the subtle changes in the brain under different experimental conditions. Pavlov started with testing dogs on how much they salivated to the presence of food in a dog food bowl. Pavlov's aim was to use the salivary conditioning method to investigate the function of the brain of higher animals in their adaptation to the external environment.
