The studies on variation of facial gestures in different cultures led to the conclusion that:
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.
