Faces display more emotions than previously believed

A new study has found that people use more facial expressions apart from portraying basic emotions like happiness, surprise, anger, sadness, fear, and disgust.

For this study, conducted at the Ohio State University, researchers wanted to focus on surprised, angry and angrily surprised faces, ABC News reported.

Researcher Aleix Martinez said that he was amazed at how limiting these basic emotional definitions were for researchers.

Martinez said that while researching he found that six was a really small number for emotions, so they divided this theory into compound facial expression and found that people display different faces when happily surprised or angrily surprised.

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