Over the last 40 years, Paul Ekman, who is an American psychologists and anthropologists has been a pioneer in the study of nonverbal communication and emotions, and in particular their relation to facial expression. Through a series of studies, he found the high level of agreement across members of Western and Eastern cultures and even in isolated cultures on selecting emotional labels that fit facial expressions. The expressions that you found to be universal include those of anger, disgust, fear, happiness, sadness, and surprise. It's presumed that these are hardwired and physiologically distinctive. You'll recognize these emotions yourself with anger, you have a flushed face, eyebrows move inwards, the nostrils flare and the jaw clenched. with fear when you scared your eyes why you pupils dilate, your upper lip rises and your lips stretch horizontally.

With disgust your nose screws up, your eyes screw up and the corners of your mouth turned down. with happiness, the coldness of your mouth rise up in a smile, your eyes like me cheeks rise and the corners of your eyebrows drop. With surprise your eyebrows raise your eyes wide, your full head wrinkles and your jaw drops open with sadness your eyelids through the corners of your mouth crawl, and the corners of your brows rise is presumed that all these emotions are hardwired and physiologically distinctive. You can show these emotions as tiny expressions and sometimes they register only in parts of the face. Sometimes the expression is shown across the entire face. Subtle expressions occur for many reasons.

For example, the emotion experience may be very slight or the emotion may be just beginning. Viewing the facial expressions of others can lead to changes in your emotional experience. Subsequently, Paul Ekman added another basic human emotion that of contempt or smugness. contempt is the only unilaterally expressed emotion and it only occurs on one side of the face, the ICU probe, the lips tighten, but it's a unilateral smile with the lip curled up on one side of the face. This emotion involves a judgement and some feeling of superiority. There seems to be some debate as to whether this is a universal emotion, but it seems to be universally expressed and it seems to be recognized by everyone
