On 28th July, Louis Roller, from Monash University, gave a talk on Zoom about human smiles, their function and the various meanings given to different types of smiles.
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.
