     A new research has uncovered that culture is a determining factor when interpreting facial emotions

(情感). The study reveals that in cultures where emotional control is the standard, such as Japan, focus

is placed on the eyes to interpret emotions. Whereas in cultures where emotion is openly expressed,

such as the United States, the focus is on the mouth to interpret emotion.

     "These findings go against the popular theory that the facial expressions of basic emotions can be

universally recognized," said University of Alberta researcher Dr Takahiko Masuda. "A person's culture

plays a very strong role in determining how they will read emotions and needs to be considered when

interpreting facial expressions."

     These cultural differences are even noticeable in computer emotions(情感符号), which are used to

convey a writer's emotions over email and text message. The Japanese emotions for happiness and

sadness vary in terms of how the eyes are drawn, while American emotions vary with the direction of the

mouth. In the United States the emotions: ) and: －)show a happy face，whereas the emotions: (or: －(

show a sad face. However, Japanese tend to use the symbol (??) to indicate a happy face, and (; _;) to

indicate a sad face.

     "We think it is quite interesting and appropriate that a culture tends to mask its emotions. The

Japanese would focus on a person's eyes when determining emotions, as eyes tend to be quite subtle

(微妙的)," said Masuda. "In the United States, where open emotion is quite common, it makes sense to

focus on the mouth, which is the most expressive feature on a person's face."
