Humans are very sensitive to faces. Faces attract attention and have an important impact on our perception of a social interaction. Faces inform us about the gender, ethnicity, age, and state of health of our interaction partners and also convey information about their likely intelligence, maturity, dominance, sociability, and many other characteristics. In addition, human faces are able to communicate information about the emotions of others. Thus, faces provide us with important hints regarding the behaviors and intentions that we may expect from our interaction partners.
It is interesting that an important aspect of emotional expressions is that they also provide social information to the decoder.
