Pavlov completed this groundbreaking study from 1891 to 1900. A dedicated technician served dog food. Pavlos noticed that the dog’s salivation didn’t just happen when he saw the food. The saliva would start when he saw the technician’s white research coat on his skin.
He used to put meat powder in the dog’s mouth uniquely at a particular time every day. If he put meat powder in the dog’s mouth, saliva would be excreted. This is a normal process. At first, the dog would prick up his ears when he heard the sound of the bell. But he would not salivate.
After a few days of practice, he just rang the bell instead of feeding at the appointed time, showing the dog’s saliva. Here, despite hearing the bell, the dog changed, resulting in salivation. The ropes or rings we see in circuses have been mastered over and over again by practice. These are also a kind of relative reflex. That is, the action that an animal responds to a relative stimulus is close.
The dog became accustomed to the process and was seen salivating only when the bell rang. He thought this was a combination of physiology and psychology. Pavlov was awarded the Nobel Prize in Medicine in 1904 for his research.
A natural stimulus can naturally produce a catalyst. But if an animal is accustomed to associating a neutral stimulus with this natural stimulus, then only a neutral stimulus without a natural stimulation can produce that stimulus later. This process is called perpetual relativity.
