     People from East Asia tend to have more difficulty than those from Europe in distinguishing facial

expressions-and a new report published online in Current Biology explains why.

       Rachael Jack,University of Glasgow researcher,said that rather than scanning evenly (均匀的) 

 across a face asWestemers do,Eastemers fix their attention on the eyes.

     "We show that Eastemers and Westemers look at different face features to read facial expressions,

" Jack said." Westemers look at the eyes and the mouth in equal measure.whereas Easterners favor the

eyes and neglect(忽略) the mouth. "

      According to Jack and her colleagues,the discovery shows that human communication of emotion is

more complex than previously believed. As a result,facial expressions that had been considered

universally recognizable cannot be used to reliably convey emotion in cross-cultural situations.

       The researchers studied cultural differences in the recognition of facial expressions by recording the

eye movements of 13 Westem Caucasian and 13 East Asian people while they observed pictures of

expressive faces and put them into categories: happy,sad,surprised,fearful,disgusted,angry,or neutral.

They compared how accurately participants read those facial expressions using their particular eye

movement strategies.

     It turned out that Eastemers focused much greater attention on the eyes and made significantly more

errors than Westerners did.  "The cultural difference in eye movements that they show is probably a

reflection of cultural difference in facial expressions,"Jack said." Our data suggest that whereas

Westemers use the whole face to convey emotion, Eastemers use the eyes more and mouth less."

       In short,the data show that facial expressions are not universal signals of human emotion.  From

here on,examining how cultural factors have diversified these basic social skills will help our understanding of human emotion.  Otherwise, when it comes to communicating emotions across cultures, Eastemers and Westemers will find themselves lost in trans- lation.
