The main idea of this passage is:

It appears from cross-cultural research that facial expressions have somewhat universal nature. For example, people in Borneo and New

Guiena who have had little contact with western culture were able to match accurately emotions with pictures of facial expression of westerners.

Further, their own facial expressions, posed to communicate different emotions, were accurately decoded by Americans. Similarly, in

the studies conducted with the children who were born blind and who therefore could not see how other facially expressed various

emotions, the children seem to use the same facial expression as their sighted peers. Studies such as these point to a universally among facial

gestures. The wide variation in facial communication that we do observe in different culture seem to reflect what is permissible and

not permissible rather than a difference in the way in which emotions are expressed facially. For example: in some culture it is permissible

openly and publicly to show the concept and discussed but in others people are taught to hide such emotions in public to display them

only in private.
