A recent study shows that for those who are afraid of mathematics, when solving the equation containing X, the nervous response is the same as when experiencing physical pain. These people have always thought that learning mathematics can't afford to hurt. Sian Beilock, a professor of psychology at the University of Chicago and an expert in the treatment of "mathematical phobia", explained this phenomenon in an article published in the Public Library of Science: Series I: "For people with mathematical phobia, the brain's response to solving mathematical problems is similar to that of putting their hands on a hot stove."

Twenty-eight adults participated in the experiment of Bayloc and Ian Lyons. Among them, 14 has a deep reverence for mathematics, while others 14 have no fear of mathematics. The researchers quantified their inner fears by observing the reactions of "patients" when they started taking math classes and handing out math books. At the same time, volunteers also agreed to have an MRI scan so that researchers could observe their brain activities.

One task: Check whether the equation is correct, such as (12*4)- 19=29. Task 2: Change the alphabetical order so that letters can be spelled correctly. The key is to remind each color: yellow means that the next problem is a math problem, and blue is a copy problem.

The results of fMRI scan show that the higher the fear of mathematics, the more active the posterior insular brain, which is directly responsible for dealing with pain. But when people are really solving problems, there is no painful reaction.

This is not the first time that researchers have found that people will suffer from certain diseases. Previously, researchers have noticed that some people will have neuropathic pain when they are rejected by others. However, human beings, as advanced thinking animals, can't learn mathematics well, which may lead to your glorious disappearance in the human evolution map.
