When experimenting with animals, place the food in one of the two containers in front of the animal, and cover it so that the animal cannot eat immediately, that is, cover the stimulus, and then release it at different times Animals, observe whether it can find food correctly. After a period of time, if the animal can still find food, this delays the response. The study found. The length of the animal's delayed reaction time is related to the species. In the evolutionary history, the delayed reaction time of different species of animals is different. For example, the delayed reaction time of monkeys is longer than that of dogs, which indicates that monkeys have a stronger ability to solve problems and their germline level is higher.
