The study shows Different ways of expressing happiness: While our faces can express a bunch of emotions – from anger to sadness, to ultimate happiness, only 35 expressions can absolutely express these feelings across cultures.
Say Hate, for example, just need one facial expression to bring its point across throughout the world. While Happiness, on the other hand, has 17–a testament to various forms of cheer, delight, and satisfaction.
Aleix Martinez, the lead author of the study said, study says, “This was delightful to discover. Because it speaks to the complex nature of happiness.”
Studies have found that the difference in the happiness of our face can be as simple as the size of our smiles or the size of wrinkles near our eyes.
The study also shows that humans use 3 expressions to express fear, four to convey surprise, and five each to tell your sadness and anger.
In the journal of IEEE Transactions on Affective Computing, the study was published.
Martinez said, “Happiness acts as a social glue and needs the complexity of different facial expressions; disgust is just that: disgust.”
The conclusions were made on Martinez’s earlier work on facial expressions, which found that people can rightly identify the feelings of other people and about 75 percent of the time based only on the delicate transformations in how the blood flow colors a person’s nose, eyebrows, cheeks, or chin.
In the study, Martinez and co-author Ramprakash Srinivasan, compiled a list of words that describe feelings–821 English words, to be exact in numbers. They then used words to reserve the internet for images of people’s faces.
Professional translators have translated those words into Spanish, Mandarin Chinese, Farsi, and Russian. In order to avoid partiality, they used each word to download the same number of pictures.
They added the words into search engines popular in 31 countries in North America, South America, Europe, Asia, and Australia, and ended up with around 7.2 million images of facial expressions in different cultures.
Psychologists debated how to categorize human emotions over the centuries. An ancient Chinese text – dating back as early as 213 BC, was revised over the years – described seven “feelings of men” as joy, anger, sadness, fear, love, dislikes and likes.
Martinez, whose research interests intersect both engineering and behavior of the human brain, although there had to be more than just seven or eight. They took 7.2 million images their searches resulted and arranged them into categories looking for those that conveyed emotions across cultures.
according to his findings and sorted them into categories, which used to express sentiments in cultures.
Martinez found they’d find at least a few hundred.
Martinez and Srinivasan assumed to recognize the facial configurations which express emotions across cultures. Based on computer algorithms, they found that the human face is capable of configuring itself 16,384 unique ways, combining various muscles in different ways.
Martinez said, they only found 35 We were shocked. She said, “I thought there would be way, way more.”
In conclusion, the researchers said that most facial expressions of emotion are universal. There are only some of them and a large number of them that are used to express joyfulness.
