When we went to school, we all learned Pavlov’s experiment on “conditional reflex”. Every time you feed a dog, you will shake the bell first. Over time, as long as the bell rings, the dog will drool, with or without food.
In fact, very few people know that Pavlov’s initial experiment was not a dog, but his younger brother who was unemployed at home. At first, the experiment was very smooth. Every time he rang, he gave his brother a slice of toast. The younger brother heard it. The reflection of saliva after the bell is also perfect, but the experiment did not develop as he imagined in the next stage. According to the theory, the younger brother should hear the ringtone and even if there is no bread, it will secrete saliva, but the experiment Instead of giving the bread slices, Ciba Luofu’s wife’s punches and kicks and his nose and face were swollen, and the experiment ended with a declaration.
