What is Brain’s Response to Fake Smile?

It is well said that “face is the mirror of your heart”. Usually people try to read other’s mind from their facial expressions. "Fear, anger, sadness, and surprise are quickly displeasure inferred in this way," says David Beltran Guerrero, a research scholar from La Laguna University. He also points out that it is not the easiest of the tasks to accomplish either since reading emotions are difficult in many cases. A whole range of ambiguous expressions exist and people resort to the more often than not. “A typical example is the expression of happiness” says Dr Beltran. Incidentally, he is one of the three experts that analyzed the capability of smile to distort effectively deductive abilities in the onlooker. While smile is one of the best expressions indicating happiness, not always people are happy even when they smile. Many times it is out of politeness that the person extends a smile to the other one interacting with him or her though intrinsically it has nothing to do with his or her happiness. Yet it has the inherent powers of hiding even negative feelings.
