Cultural Differences in Reading Emotions
People from East Asia tend to have more difficulty than those from Europe in distinguishingfacial 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 Easternersfavor the eyes and neglect (忽略) the mouth.
According to Jack and her colleagues, the discovery shows that human communication of emotionis 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 recordingthe eye movements of 13 Western Caucasian and 13 East Asian people while they observed picturesof expressive faces and put them into categories : happy, sad, surprised, fearful, disgusted, angry, orneutral. 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 significantlymore errors than Westerners did. "The cultural difference in eye movements that they show is probablya reflection of cultural difference in facial expressions," Jack said."Our data suggest that whereasWesterners 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 emotions. Fromhere 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,Easterners and Westerners will find themselves lost in translation.
