Facial Expressions

Mary Duenwald wrote the article about Paul Ekman and his study of micro expressions. She talks about his background some, and then tells his philosophy and the seven categories our expressions are put into. Then he goes on to tell about the involvement of micro-expressions in our country’s security.
Connection
The seven categories of micro expressions are sadness, anger, fear, happiness, surprise, contempt and disgust (Duenwald). In sadness “the eyelids droop as the inner corners of the brows rise and, in extreme sadness, draw together. The corners of the lips pull down, and the lower lip may push up in a pout (Duenwald) .” In fear “the eyes widen and the upper lids rise, as in surprise, but the brows draw together. The lips stretch horizontally.” In surprize “the upper eyelids and brows rise, and the jaw drops open (Duenwald) .” Contemptment. “ is the only expression that appears on just one side of the face: One half of the upper lip tightens upward.” In happiness, “the corners of the mouth lift in a smile. As the eyelids tighten, the cheeks rise and the outside corners of the brows pull down.” In anger, “both the lower and upper eyelids tighten as the brows lower and draw together. Intense anger raises the upper eyelids as well. The jaw thrusts forward, the lips press together, and the lower lip may push up a little.” In disgust, “the nose wrinkles and the upper lip rises while the lower lip protrudes.” Showing surprise, “the upper eyelids and brows rise, and the jaw drops open (Duenwald).” We can use these expression to find terrorist in our country and find the lyers that live all around us. But would this really help knowing that you are being lied to? I feel it will help in our government and politics to know who is really going to help or country but what if someone makes a mistake and says someone was lying when they really wern’t. It is easyer to tell if someone is lying than to tell if they are telling the truth.
