"'We show that Easterners and Westerners look at different face features to read facial expressions,' said Rachael E. Jack of The University of Glasgow. 'Westerners look at the eyes and the mouth in equal measure, whereas Easterners favor the eyes and neglect the mouth. This means that Easterners have difficulty distinguishing facial expressions that look similar around the eye region.'

The discovery shows that human communication of emotion is a lot more complex than experts had believed, according to the researchers led by Roberto Caldara at The University of Glasgow. As a result, facial expressions that had been considered universally recognizable cannot be used to reliably convey emotion in cross-cultural situations."
