Some of the thought leaders in understanding facial expressions in all humans are said to be Paul Ekman, of course, and Wallace V. Friesen. They are both psychologist that understand the human facial expressions. In their studies they went around the world to different types of groups. Such as tribes or villages. I think they also went to some more modern day places as well. They found out that, even through babies, the same facial expressions are made between anyone in the world. This could lead to such a more understanding of how people can work with one another!! Especially in the business world or even in schools.
Mostly Ekman is the man who is famous for his research and understanding of this universal language. He is written several books on his discoveries and even has classes that are able to teach people, like you and me, how to be able to read emotion. With this knowledge and understanding, I think that it would be useful in my future job career. Especially, if I am working with others.
Some other individuals that have used this research is: Robert Zajonc and Carrol Izard. They are both psychologist who have published articles about the evolution of emotion--also known as facial feedback.This theory that Robert proposed suggested that the facial musculature of mammals can control the temperature of the base of the brain (in particular the hypothalamus) by varying the degree of forward and backward flow through a vascular network." But there is not too much information about his theory. As for Carroll, he talked about the gains and loses associated with the evolution of emotion. Some of the loses that are presented is are we losing some of our emotional expression through our everyday language or is it still be seen today? Some of these questions have rises throughout this field of research and how the understanding of the evolution of emotion can change how we see one another.
