British psychologists claim that everything you think about the new person you have just met within the first 30 seconds of conversation, is true. Even though the amount of time is short, our intuition works at full capacity. Without even wanting to, we take in their posture, gaze, clothes, haircut, facial expression and figure out their significance.
Posture is also a giveaway - our body reveals what we're thinking about. Very often, men sit with their legs wide apart. Subconsciously, this is seen as sexual aggression. And men themselves don't even suspect this.
If a woman sits on a chair with her legs apart, revealing everything under her short skirt, a man cannot think about anything other than what is in front of him. She agitates the man, sometimes without even knowing it. And if he allows himself some freedom, she is even offended, without finding out the cause.
Whenever a person decides to relax their body in order to look calm before an important meeting, he is actually making a mistake. Because he does not notice that besides relaxing his body, he has also loosened up the muscles on his face, as well as on the vocal apparatus. This causes his speech to become unrecognizable.
Many reactions in the communication between people are based on primal instincts. Whenever a door opens and everyone has their backs to it, they all turn around at the same time to see who's coming in. This is a primal instinct of self-preservation. Mannerly people do not turn around, instead, they notice who's entered with their peripheral vision.
If you know enough about human reactions, you will know how to provoke them. Everything that moves draws attention. Imagine a room where a conference is being held.
Swing your leg or move your hand with a pen through the air and you will notice how everyone is staring at you, instead of the person speaking at the time.
