People use fluent eyes language from birth

A study recently published in the Journal of the American Academy of Sciences has demonstrated that human eyes are not only used to capture images but also perform the opposite process, using eyes to express thoughts, moods. Moreover, this ability is formed as an instinct very early in one's life. This two-way government helps explain why we can look at other people's eyes to know their thoughts, feelings and emotional state.

The eyes are the windows of the soul. You see the world every day with your eyes and you can also through your eyes to "see" the thoughts and moods of others. By looking at the eyes of others, you can identify a loving couple, the fear of a child or even a teacher who can use the eyes to know which students are cheating during the test. So, how does a black, white sphere with a transparent coating fit in the skull can help people understand the love, fear or cheating of others.

A new study led by Sarah Jessen from the Max Planck Institute and Tobias Grossmann at the University of Virginia explains that. The research results have been published at the recent National Academy of Sciences.

The human eye has a larger white area than many other animals, making it easy for people to keep track of everything around them. For most people, including babies, focus on the eyes when looking at the faces of others. For people with autism, the ability to read other people's minds will be problematic and they will no longer be able to focus on the eyes of others. Therefore, these people often have difficulty communicating or facing others. All this has formed the hypothesis that eyes are an important tool to help us observe and understand the feelings of others through their eyes.

If so, even babies can detect emotions from other people's eyes and especially from their whites. In a demonstration experiment, the researchers sketched out different states of the eyes, from fear to neutrality. These states are mainly caused by the position of the white. They then showed the babies the pictures in a time of just 50 milliseconds, while using the ERP technique to analyze the child's brain waves to determine, they are aware of the differences in eyes or not.

The results showed that the brain waves of the children were markedly different when they looked at fearful eyes and normal eyes. The difference in brain waves is most pronounced in the anterior brain area - the area of ​​attention control and close association with the area of ​​the brain that detects fear. For comparison, the researchers also used the sketches above, but the colors were reversed from black to white, white to black and for the children to observe again. At that time, their brain waves did not differ.

Therefore, the researchers concluded that we not only have a very deep view of different states of other people's eyes, but we can also identify their emotional states based on the region. white irises . At the same time, our eyes are not only a tool to observe and receive images for the brain but also have the opposite function, the brain will perform many complex calculations and adjust the gesture of the eyes to Let people know, what we are thinking and how we feel.
