До ть будь ласка потрібно виписати дієслова потрібно дуже терміново Psychologist Paul Ekman has made a lifetime study of how people act when they lie. Usually they not only want the hearer to believe the words they are saying; they also want to cover up some strong emotion that they are feeling such as guilt, shame, fear, anger, pain, or even pleasure. In addition to telling the lie, they want to conceal that emotion, and the easiest way to do this is by trying to substitute the signs of a different emotion. By noticing the contradictions between their words and their behavior, Ekman found that he could often catch them in the act of lying.
Ekman concludes that there are four kinds of behavior that can give a lie away: the liar's words, voice, body, and face. He says that the hardest task for liars is to control their words and face, since they assume that that's what the listener will he paying attention to. Consequently "lie catchers" should also pay close attention to the speaker's voice and body signals, which she may forget to control. He then points out what the lie catcher should look for in deciding whether he is being deceived.
