The body language It allows us to expose or reinforce the verbal message that we are sending during a communication, allowing us to reveal our feelings, emotions and perceptions to our interlocutor. This encompasses a variety of resources, the most important being the look and facial expression, as both are the most important means of expressing emotions and moods.
The face reflects the attitudes, reactions before others and the emotions that a person feels at a certain moment. Therefore, within facial expressions, the smile becomes especially important because through it we can transmit different messages and also hide emotions. A smile can communicate interest, it can soften rejection or communicate a friendly attitude.
It receives its name in honor of the French medical researcher Guillaume Duchenne, who in the 19th century detected this lip expression while researching the physiology of facial expressions. This is generally considered to be the most genuine and spontaneous smile. According to Duchenne, the smile involves the contraction of the major and minor zygomatic muscles near the mouth, which elevate the corner of the lips, and the orbicularis muscle near the eyes, whose contraction raises the cheeks and produces wrinkles around the eyes.
TYPES OF SMILES
There are many types of smiles, each one has a special meaning depending on what the person feels inside (pleasure, joy and fun and even sadness). American psychologist Paul Ekman distinguished no less than eighteen different types of smiles and described the specific facial expressions and muscles of the face involved. Some of them are:
The zygomatic muscle participates, the cheeks rise and crow's feet (wrinkles around the eyes) come out. The latter are the best indication that this gesture is derived from a feeling of real joy. This smile lasts longer when the positive feelings are very intense.
Lips tighten, crow's feet come out, and the corners of the lips stretch. This smile reflects positive feelings while hiding the intensity.
In this smile it lacks the participation of the eyes as it happened in the Duchenne smile (elevation of the orbicularis muscle near the eyes, whose contraction raises the cheeks and produces wrinkles around the eyes) and suggests that the person is faking true happiness .
The lips are raised at a very steep angle. He is known as Chaplin's Smile.
No positive expression is observed in it; the risorio muscle pulls the lips towards the ears and the lips remain in a rectangular position.
Contraction of the orbicularis labialis muscle, bulge around the corners and sometimes dimples.
It is asymmetric and long. Usually it implies that the person is not going to complain, he shows negative emotions without wanting to hide the misery.
THE SMILE ON THE ORATORY
Smile is the speaker's best cover letter. A fresh, genuine, charming and above all sincere smile is useful to delight the audience when starting a speech. It is also an excellent resource every time the message transmits joy, fun or achievement, since it will be able to reinforce it in such a way that those who listen to it feel it with almost the same intensity as those who present it.
