Background
The scientific study of the facial expression of emotion began with Charles Darwin’s The Expression of Emotions in Man and Animals, first published in 1872. Among his many extraordinary contributions Darwin gathered evidence that some emotions have a universal facial expression, cited examples and published pictures suggesting that emotions are evident in other animals, and proposed principles explaining why particular expressions occur for particular emotions—principles that, he maintained, applied to the expressions of all animals. But Darwin did not consider at any length when, how, and why emotional expressions are reliable or misleading. EKMAN (2003).
Allow me to revive an old idea about the mind. This idea is that the mind arises from, and is principally about, our sensory-motor interaction with the world. It is the idea that all our sense of the world, of space, objects, and other people, arises from our experience squeezed through the narrow channel of our sensation and action. This radical view is but, in many ways, an appealing one. It is only radical because it says that experience is the only thing that we directly know, that all our sense of the material world is built around the concept of explaining our subjective experience; not just that the mental is made primary and held above the physical, but that the subjective is raised over the objective.
What is Facial Action Coding System?
Facial Action Coding System (FACS) is the most widely used and versatile method for measuring and describing facial behaviors. Paul Ekman and W.V. Friesen developed the original FACS in the 1970s by determining how the contraction of each facial muscle (singly and in combination with other muscles) changes the appearance of the face. They examined videotapes of facial behavior to identify the specific changes that occurred with muscular contractions and how best to differentiate one from another. They associated the appearance changes with the action of muscles that produced them by studying anatomy, reproducing the appearances, and palpating their faces. Their goal was to create a reliable means for skilled human scorers to determine the category or categories in which to fit each facial behavior. The FACS Manual was first published in a loose-leaf version with video or film supplements in 1978. EKMAN, FRIESEN, HAGER, (2003)
An individual might for example, know that a certain action tends to be followed by a certain sensation, or that one sensation invariably follows another. But, these are its sensations and its actions. There is no necessary relationship between them and the sensations and actions of another individual. To hypothesize such a link might be useful, but always secondary to the subjective experience itself.
Emotions such as fear, anger, and surprise, respond to various external stimuli or events, represent psychological states that also disrupt the internal stability of the body.

In learning about stress, the most important concept concerning great clinical relevance, is that the stress response can be both beneficial and detrimental to the organism. There are many complex factors that determine whether the organisms response to stress leads to adaptation and resilience (beneficial), or maladaptation and dysfunction. An appreciation of the concept of stress and its basic biological underpinnings is essential to the understanding of both health and disease processes.
Occasionally we experience something subjectively, but later we determine that it did not objectively happen. For example, we felt the room get hot, but the thermometer registered no change. In this view there is a reality independent of our experience. This would be easy to deny if there were only one agent in the world. In that case it is clear that that agent is merely inventing things to explain its experience.
Theories
There are not two kinds of things, the mental and the physical. There are just mental things:
