What is a smile? Why do we smile? Do all smiles mean the same thing? Or, as Shakespeare wrote, “One may smile, and smile, and be a villain.

Louis Roller will discuss the function of smiles and the various meanings given to different types of smiles.

A smile is formed primarily by flexing the muscles at the sides of the mouth. Some smiles include a contraction of the muscles at the corner of the eyes, an action known as a Duchenne smile.

Among humans, a smile expresses delight, sociability, happiness, joy or amusement. It is distinct from a similar, but usually involuntary, expression of anxiety known as a grimace.

Although cross-cultural studies have shown that smiling is a means of communication throughout the world, there are large differences among different cultures, religions and societies, with some using smiles to convey confusion or embarrassment.
