3% of the population is suffering from a syndrome that we all never knew

There is a very strange syndrome, but it affects 3% of the population. But miserable, people can get it but don't realize it.

You may have heard of a very strange form of disorder syndrome, making it impossible for infected people to recognize the faces of others, regardless of familiarity. The syndrome is called prosopagnosia - also called blindness syndrome .

This is what happens if you have face blindness syndrome.

However, it is true that very few people know that prosopagnosia also has a little brother who has heard of it, and even does not know it. It is phonagnosia - blind syndrome . voice - a sick person cannot recognize his or her own voice. And even more surprisingly, only 3% of the population suffers from this syndrome.

According to a study at the University of Southern California on 730 candidates, only 23 cases have phonagnosia, and most of them don't even realize it.

There is a voice blindness syndrome, and it only accounts for 3% of the population.

More specifically, the survey participants were treated to 100 celebrities, and answered whether their voices were familiar or not. Most think that they will recognize the voices of these people. Next, the candidates will hear 2 recordings: 1 segment of the average person, and the rest of the celebrity.

The test also required them to imagine, asking how easy it was to imagine the voice of a celebrity compared to "lifeless" sounds like car horns, broken glass .

As a result, 76% of participants can correctly guess the celebrity's voice. However, there was 3.2% for the score was too low, and experts said they were incapable of recognizing speech - the symptoms of phonagnosia.

We still know so little about phonagnosia.

Currently, this is one of the first studies on phonagnosia, in other words, we have very little knowledge of this syndrome. Until now, experts have not been able to identify the cause of phonagnosia formation, only one thing is certain that the syndrome may be congenital.

However, the research team believes that this finding could help the public to learn more about a form of disorder, thereby offering effective treatments for more dangerous psychological illnesses.

The study was published in the British Psychology Society magazine.
