Studies by Ekman’s group have demonstrated that humans share a set of universal emotional expressions that testify to the common biological heritage of the human species. Smiles, for example, signal happiness and frowns indicate sadness on the faces of people in such far- flung places as Argentina, Japan, Spain, Hungary, Poland , Sumatra ,the United States, Vietnam, the jungles of New Guinea , and the Eskimo villages north of Artic Circle. Ekman and his colleagues claim that people everywhere can recognize at least seven basic emotions: sadness, fear, anger, disgust, contempt, happiness, and surprise. There are, however, huge differences across cultures in both the context and intensity of emotional displays – the so called display rules. In many Asian cultures, for example, children are taught to control emotional responses – especially negative ones- while many American children are encouraged to express their feelings more openly. Regardless of culture, however, emotions usually show themselves, to some degree , in people’s behavior. From their first days of life, babies produce facial expressions that communicate their feelings.
