People from East Asia tend to have more difficulties 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 as Westerners do, Easterners fix their attention on the eyes.

"We show that Easterners and Westerners look at different face features to read facial expressions," Jack said. "Westerners 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 Western 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 Easterners focused much greater attention on the eyes and made significantly more errors than did Westerners. "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 Westerners use the whole face to convey emotion, Easterners 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 under- standing of human emotion. Otherwise, when it comes to communicating emotions across cultures, Easterners and Westerners will find themselves lost in translation.

赵立国与余庆华合伙承包村里的水塘养虾。水塘的上游有一家集体造纸厂。2003年5月，赵立国、余庆华二人向水塘投放虾苗2万尾。投放后赵、余二人精心管理，日夜看护。10天后，二人发现塘内有少量的死虾出现，当即捞起部分死虾送造纸厂与其交涉。造纸厂派人到现场了解情况。经双方估算，塘内漂浮和打捞上岸的死虾约5000尾。厂方把死虾送市商品检验处化验，化验结论是虾苗死亡可能是排出的废水毒死，但不能肯定。市环保部门对造纸厂排出废水的检验结果是该厂排出的废水量没有超过国家规定的排污标准。由于赵、余二人与造纸厂之间关于赔偿问题不能达成一致意见，二人遂向法院起诉，要求赔偿损失。在举证期间内，原告赵立国、余庆华二人提供的证据材料有：(1)2003年5月10日购买2万尾虾的发票，发票载明了单价及总金额；(2)原告与村里签订的承包合同；(3)估算死虾 5000尾的书面材料，原告及被告派到现场查看人员都在上面有签名；(4)赔偿费用一览表及计算方法； (5)李某的证言，证明在送检过程中商品检验处的检验员蔡某与厂方有过两次私下的接触。李某后到庭作证。被告造纸厂不同意赔偿，提出，了以下证据材料：(1)市商品检验处的化验报告；(2)市环保部门的检验报告。在诉讼过程中，原告提出申请重新鉴定虾的死亡原因，法院指定由省级有关部门做出了新的鉴定结论。 问题：
