Faces Display 15 More Emotions Than We Actually Believed!

Faces Display

A new study conducted by the Ohio State University has revealed that people use more facial expressions than the ones we already knew. Along with showing basic emotions like happiness, surprise, anger, sadness, fear, and disgust, they have discovered 15 more expressions. Until lately, scientists had only identified six basic human emotions which expressed happy, sad, fearful, angry, surprised and disgusted. These emotion categories are defined by the facial muscles we use to express each emotion but human feelings appear definitely more complex than just what the physical face exhibits.

One of the researchers, Aleix Martinez said that while conducting the study, they found that six emotions were not enough, so they divided this theory into compound facial expression and found that people display different faces when they are happily surprised or angrily surprised.

They studied different muscle movements and found that there are additional 15 distinct emotional expressions that could be used to help people with behavioral problems to understand emotion or even be used to help robots of the future have better interactions with people.

In the new study published in PNAS journal, the researchers have explained about the 15 new compound emotions. These emotions are expressed by combining the basic emotions, like angrily disgusted, fearfully happy and happily surprised. For instance, when people are happy they raise their cheeks, part their lips and pull the corners of their mouth out. These distinctive facial patterns were constant among all 230 volunteers.

The recently identified emotions could affect future researches on psychiatric disorders such as schizophrenia or PTSD, research on developmental disorders like autism and create better human-computer interaction systems. Scientists also believe that mapping the human spectrum of emotion is especially useful for making robots that will be able to understand what humans are feeling much more accurately.
