Recently one series caught my attention, it's the American television series Lie to Me. In the series, Dr. Cal Lightman (Tim Roth) and his colleagues assist in investigations, reaching the truth through applied psychology: interpreting micro-expressions, through the Facial Action Coding System, and body language.
Dr. Cal Lightman is the world's leading deception expert, a scientist who studies facial expressions, body language, voice and words to discover if someone is lying and why. Lightman can spot what are known as "micro-expressions" – split-second, involuntary facial expressions that reveal what a person is really feeling.
Well, I should mention that it's not the cases they resolve that caught my attention, but the methods they use to reach the truth. Here is something I found about body language (a form of non-verbal communication):
1. Arms crossed across the chest. This can indicate that a person is putting up an unconscious barrier between themselves and others. It can also indicate that the person's arms are cold which would be clarified by rubbing the arms. When the overall situation is amicable, it can mean that a person is thinking deeply about what is being discussed. But in a serious or confrontational situation, it can mean that a person is expressing opposition. This is especially so if the person is leaning away from the speaker. A harsh or blank facial expression often indicates outright hostility.
2. Consistent eye contact can indicate that a person is thinking positively of what the speaker is saying. It can also mean that the other person doesn't trust the speaker enough to "take his eyes off" the speaker. Lack of eye contact can indicate negativity. If a person is looking at you but is making the arms-across-chest signal, the eye contact could be indicative that something is bothering the person, and that he wants to talk about it. If the person looks from one eye to the other then to the forehead it is a sign that they are taking an authoritative position. If they move from one eye to the other then to the nose, that signals that they are engaging in what they consider to be a "level conversation" with neither party holding superiority. The last case is from one eye to the other and then down to the lips. This is a strong indication of romantic feelings.
3. Disbelief is often indicated by averted gaze, or by touching the ear or scratching the chin.
4. Boredom is indicated by the head tilting to one side, or by the eyes looking straight at the speaker but becoming slightly unfocused.
5. Deceit or the act of withholding information can sometimes be indicated by touching the face during conversation. Recently, evidence has surfaced that the absence of blinking can also represent lying as a more reliable factor than excessive blinking.
I am very pleased with this series and I recommend you to watch it, especially if you are interested in non verbal communication like me :happy:
