　　According to foreign media reports, the new study believes that mice will regret the lack of better food. This is the first time we have found regrettable behavior in mammals other than humans. Neuroscientists at the University of Minnesota designed the experimental conditions. In this case, the mouse must choose between waiting for a certain amount of time to obtain food or eating another food. It is regrettable that the mice correct their decisions in subsequent experiments.

　　The mouse left and found that the new food had deteriorated. He felt sorry. This shows that behaviors like regret can influence the future decisions of rodents and eliminate the idea that regret belongs to humans only. Professor Davideddish of the research team said: "The difference between regret and disappointment is very important, and this is also a problem we must solve."

　　They designed a task called "Food Street" and provided additional food every 60 minutes so that the rats could choose the time to wait. Professor Redish said: "It's like queuing in a restaurant. If the line in a Chinese restaurant is too long, you can give up and go to another restaurant."

　　Sometimes, mice won't wait, it will only get worse. caution. Choose, scientists call this situation a condition that causes regret. In these cases, the rat will usually stop and then look back at the missing food. They are also more likely to wait in the next area and eager to change their next decision and enjoy the next food. Researchers say this behavior is consistent with feelings of regret.

　　If the mouse does not make the right decision and encounters the wrong choice, it will regret its behavior. "When humans regret it, when humans regret it, the preorbital frontal cortex becomes very active. We found a similar situation in mice.

　　Interestingly, mice will not regret not having enough food, because humans will not regret not because they did not get something, but because they did not. It's like doing it. Professor Redish believes that the regret pattern of such animals can help us understand how regret affects people's decisions.
