阅读理解 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.' 1.
