Hi everyone, have you ever heard of Pavlov and his classical conditioning theory? This month I want to share his history and findings with you.

Ivan Petrovich Pavlov was a Russian Physiologist, who was interested in the digestive system of human and animals. He had won a noble prize for physiology in 1904. Pavlov was interested in the gastric function of dogs. In 1890 he used his own dog for experiment. He expanded the salivary gland of his dog, so that he could collect and measure its saliva under different food conditions. Through this experiment, he found out how dogs’ gastric function works and it made him the first physiology noble prize winner. Other than that, he had also found out an extra psychic condition which he called it “classical conditioning”.
At first, there was no reason that the dog would generate saliva when it heard a bell sound. However, Pavlov paired up the bell sound with food. After several times of conditioning, the dog would salivate when the bell rang. This is “classical conditioning” that the dog associated between the two stimuli so it expected to have food when it heard the bell sound.

It can apply to many situations in daily life, for example, have you ever noticed that baby product advertisements always use cute babies to be their models? The advertising agencies try to attract parents by associating beautiful babies to the products through classical conditioning.
