What needs to be done to form a reflex?

Only a conditioned reflex can be formed. Experiments on the formation of conditioned reflexes were carried out by Pavlov. He established that in order to form a reflex, it is necessary to constantly repeat a certain action. In his studies, dogs excreted gastric juice when a light bulb was turned on when they were given food at the same time. After a while, the secretion of gastric juice was noted only when the light was turned on. The conclusion is that in connection with the frequent repetition, a reflex has formed.
