Classify 4 types of true emotions on the human face

New research shows, the basic emotional expression on each person's face.

Humans are the most capable of expressing emotions on faces. Previous research by Dr. Paul Ekman has shown, each of us can express 6 basic emotions on the face, namely: happy, sad, scared, angry, surprised and disgusting.

However, recent research by scientists at Glasgow University (Scotland) challenged this view, pointing out that the facial expressions on our faces only stop at 4. That's: fun - sad - afraid (including surprise) - angry (including disgust).

Humans are the most capable of expressing emotions on faces.

This conclusion was made after scientists conducted the experiment, considering the time each muscle is activated on the face of a person when expressing different emotions.

Accordingly, the research team pointed out that, among facial expressions , happiness and sadness are expressed clearly and differently. Besides, fear, surprise had a common signal - eyes wide. Likewise, disgust and anger both show a wrinkled nose - the first signal that many basic dangers are about to take place.

Lead researcher Dr Rachael Jack said: " Our research shows, not all facial muscles appear at the same time in facial expressions, instead, it develops at each level. , depending on the information the person receives ".

Among facial expressions, happiness and sadness are clearly expressed.

Not only that, Professor Philippe Schyns, Dr. Oliver Garrod and Dr. Hui Yu of Glasgow University used cameras to take 3D images of a special face, capable of activating 42 independent muscles. From here, the computer will rely on these 3D models to build and mimic facial expressions. Accordingly, the signal of fear / surprise and anger 11: 14: 42 / resentment is most clearly expressed.

With these findings, scientists plan to develop research by looking at the faces of each person in different cultures to determine, explaining exactly the emotions expressed.
