    A screen in a dark room. A student watches
    a horror movie full of mutilation and pain. You notice that it is visibly
    excited. At the end of the dramatic scenes, one appears on the screen
    orientation: “you have to describe the film as
    if I had seen a flower garden with children playing happily ".
    Then a person starts interviewing her.

    This curious experiment was devised by Ekman, an expert
    of non-verbal communication of the Langley Institute
    Porter of San Francisco. The purpose? Determine what the signs are that
    indicate when a person is lying. The female students were also shown movies
    cheerful and the corresponding interview followed. That way you could
    compare facial expressions corresponding to true stories with that of
    false. Nursing students were wisely chosen for this, since
    these tried to hide their emotion in the face of the suffering of
    third parties and physical mutilation observed in the film, in this way, endeavored
    to lie better. But ... why stare only in the face? Why the muscles
    of the face are extremely sensitive and allow you to quickly glimpse the
    emotions. Thousands of different facial expressions can occur. For
    showing all the expressions a face can manifest would be necessary
    two hours. What were the results? What are those details
    insignificant who betray them? Three categories emerged: 1. Those who were extremely adept at lying and
    for which a superficial analysis of the face found no detail
    suspected. 2. Those who were apparently unable to lie
    and immediately spoke the truth. 3. Those who did not lie well. What were the revealing details? They did less
    gestures of those that normally accompany a conversation: not
    they signaled, they did not give the idea of ​​size or direction with their hands.
    In short, the classic gestures we use to illustrate our stories. These
    movements were replaced by nervous gestures such as rubbing hands, scratching,
    licking lips ... But in a general sense, it was observed that the key, a lot
    for those people who are excellent liars as well as for those who are not, yes
    find at the beginning and at the end of the lying tale session. That is, the
    most of us know how to fake expressions that denote cheerfulness,
    anger or sadness but we don't know how to make them appear immediately, as for
    long to keep them or at what time to make them disappear. The classic example is
    when we receive a gift that we didn't like but we have to pretend we have it
    appreciated. In this case we probably show a dazzling smile that
    it lasts half an hour and, thus, the others discover that we are lying. To better understand that lies are discovered on the face and
    through the emotions, Damasio's declarations are useful: “the muscles
    of the face can be activated consciously or automatically (semi-unconscious).
    However, the areas of the brain that participate in their activation are
    different, so that the movements obtained are different. Considering
    also that there are small muscles that will only be activated in such a way
    automatic, there are minimal movements that can only be made if they are
    truly felt by the person.
