the human face only had four basic expressions of emotions. This is because some pairs of emotions are impossible to tell apart, especially when they are first shown on the face. Fear and surprise, both share wide-open eyes. The facial expressions for anger and disgust also look the same.

　　So if our faces are only able to express four basic emotions, how do we communicate much more complex feelings? The study found that the way expressions are understood is different in different cultures. Lead researcher Rachael Jack was studying this because "facial expressions were considered to be universal", she explained. However, while looking at how people from the East and West recognize different parts of the face, they found that although there are some common features across cultures, the six basic facial expressions of emotion are not recognized universally.

　　"We said we don't know what a disgust face looks like in China, so the best way to go about that is to make all combinations of facial movements and show the Chinese people and ask them to choose the ones they think are disgust faces." With the software they developed, they discovered that in the early stages of signaling emotion, fear and surprise, and anger and disgust, were often confused. Jack explained that this development of facial expressions is related to biology and social situations.

　　What has caught people's interest is the cross-cultural aspect of the work. "This study shows which emotions we share, and which are different in different cultures," Jack said. This finding could help us develop new communication technologies, for example ones that use video-calling programs like Skype. When you talk to someone in Japan in the future, a programme could "read" your facial expressions and then "translate" them for the Japanese person. The Japanese person would see the Japanese facial expression on their screen. In this way, people from different cultures could understand each other better.
