We use smiles for several reasons. It is a social response, a reward, a sign of affiliation, and even an act of dominance. While the actual meaning of a smile is still unknown, its appearance and expression can have profound psychological effects. Let’s look at three different types of smiles and how they are triggered by our emotions. All three types of smiling have their own set of psychological effects. If you want to make the world a happier place, start smiling.
The first type of smile is the cuspid smile pattern. This smile has the central incisors located below the maxillary molars. Famous people with this type of smile include Tom Cruise, Elvis, Drew Barrymore, and Linda Evangelista. The second type is the ecto-coronal smile, where the central incisors are located above the maxillary molars. Other ectomorphic smiles involve asymmetrical teeth arrangement.
Another kind of smile is the zygomaticus major muscle. A study published in PNAS in 2014 showed that deceivers repeatedly fired the zygomaticus major muscle (the muscle that pulls the lips into a smile) while the victim was acquitted of murder. But genuine grief does not trigger the firing of the zygomaticus major muscle. In the movie “Steel Magnolias,” this muscle is shown to be triggered by the actor’s face during a scene in which the family is reunited.
In the same way that laughter makes us feel good, smiling can make you feel better. Scientists have found that it can make us feel good. It also protects our health, as well as our emotional state. In fact, it may even help our body recover from illness. A study conducted by the National Institutes of Health shows that smiling can even help us cope with physical pain. If you think that your smile can be trained, you’re wrong.
The smirk is a socially acceptable way to show sadness. Researchers have analyzed videos of people publically pleading for their missing relatives. Half of the people analyzed were convicted of murder. In this case, the deceivers were able to successfully manipulate the victims by repeatedly firing the zygomaticus major muscle, which pulls the lips into a smile. This is a very interesting study that proves the social value of smiling in the face of grief.
A cuspid smile is one that is characterized by the molars in the mouth below the central incisors. Some famous people with this type of smile have a cuspid-type of teeth. Some of them have a typical, unidirectional smile. Others have a more complex pattern, which is why they have a cuspid-typed mouth. And the molars in the back of their mouths are not the only ones with this type of molars.
