The story now knows about the sound that everyone should hear

It was the claw of nails. And this truth will surprise you.

Have you ever heard the sound of nails scratching the table and shuddering? If so, it is likely that you will fall into a team that is afraid of this sound - every time you hear it, you will feel horrified.

And the truth is not only this sound. The sound of a sharpening knife on a plate, a nail scratching a glass door, or a friction rubber . all create a fear for many of us.

However, do you know, what is this fear of the name? It turns out it has a name, and its name is "Grima" - a Spanish word. Even the word has been around for a long time, and psychologists think it is a separate emotion.

This is a kind of feeling that has never been known.

Dr. Inge Schweiger Gallo, a researcher at Complutense University in Madrid, said: "For me, I was afraid to touch all kinds of foam pads - like those used to prevent shock when transporting. If I had to touch them, I would ask people. other household " . This experience made her decide to do research, to see how people react to this fear.

As a result, they found that this was a kind of feeling that had never been known. It is not like "disgust" , and it is a reaction from emotions. Moreover, "grima" is a word that cannot be translated into another language, either English or Vietnamese.

Why else? In general, the candidates who participated in the study evaluated these sounds as "uncomfortable" and "uncomfortable". But compared to the "disgusting" feeling, most think that this feeling is worse.

Ghima is a form of emotion, a new fear.

Moreover, the heart rate when hearing the sound for the "grima" feeling, their heart rate decreased but quickly spiked. Meanwhile, with the sound lining the scary line, their heart rate plummeted.

In short, research shows that "grima" is a bit like a "disgust" feeling, but still a form of emotion, a new fear.

The study was published in Frontiers in Psychology magazine.
