Faces are special in that they represent the first things we interact with, even before words are spoken. They are a fundamental part of human communication and have the ability to communicate a wide range of emotions and reactions, sometimes before the person has even had the chance to utter a single word. Faces provide insight into both a person's mood and personality. We are able to use our facial expressions to convey to others what we are thinking and feeling. This nonverbal form of communication between people has been found to be essential in forming relationships, making it easier to connect and trust. Finally, faces have a strong connection to identity and memory. People recognize faces faster than and more accurately than any other type of object, which makes it easier to remember and identify people, even if we were only briefly acquainted in the past. Furthermore, faces are sometimes seen as a gateway to a person’s soul and inner thoughts, making their study and understanding an age-old fascination of researchers and scientists alike.
