The face is crucial for human identity, and damage such as scarring or developmental deformities affects the psyche adversely.

Shape
The face is the feature which best distinguishes a . Specialized regions of the , such as the fusiform face area (FFA), enable facial recognition; when these are , it may be impossible to recognize faces even of intimate family members. The pattern of specific organs, such as the eyes, or of parts of them, is used in biometric identification to uniquely identify individuals.

The shape of the face is influenced by the of the , and each face is unique through the anatomical variation present in the bones of the (and ). The bones involved in shaping the face are mainly the , , and . Also important are various , such as , and (of which color may vary).

Function

Emotion
Faces are essential to expressing , consciously or unconsciously. A frown denotes disapproval; a smile usually means someone is pleased. Being able to read emotion in another's face is "the fundamental basis for empathy and the ability to interpret a person’s reactions and predict the probability of ensuing behaviors". One study used the Multimodal Emotion Recognition Test Multimodal Emotion Recognition Test (MERT) | Swiss Center for Affective Sciences . Affective-sciences.org. Retrieved on 2011-04-29. to attempt to determine how to measure emotion. This research aimed at using a measuring device to accomplish what people do so easily everyday: read emotion in a face.

The muscles of the face play a prominent role in the expression of emotion, and vary among different individuals, giving rise to additional diversity in expression and facial features.

People are also relatively good at determining if a smile is real or fake. A recent study looked at individuals judging forced and genuine smiles. While young and elderly participants equally could tell the difference for smiling young people, the "older adult participants outperformed young adult participants in distinguishing between posed and spontaneous smiles". This suggests that with experience and age, we become more accurate at perceiving true emotions across various age groups.


Perception and recognition of faces
Gestalt psychologists theorize that a face is not merely a set of facial features, but is rather something meaningful in its form. This is consistent with the Gestalt theory that an image is seen in its entirety, not by its individual parts. According to Gary L. Allen, people adapted to respond more to faces during evolution as the natural result of being a social species. Allen suggests that the purpose of recognizing faces has its roots in the "parent-infant attraction, a quick and low-effort means by which parents and infants form an internal representation of each other, reducing the likelihood that the parent will abandon his or her offspring because of recognition failure". Allen's work takes a psychological perspective that combines evolutionary theories with Gestalt psychology.


Biological perspective
Research has indicated that certain areas of the brain respond particularly well to faces. The fusiform face area, within the , is activated by faces, and it is activated differently for and social people. A study confirmed that "when viewing images of strangers, shy adults exhibited significantly less activation in the fusiform gyri than did social adults". Furthermore, particular areas respond more to a face that is considered attractive, as seen in another study: "Facial beauty evokes a widely distributed neural network involving perceptual, decision-making and reward circuits. In those experiments, the perceptual response across FFA and LOC remained present even when subjects were not attending explicitly to facial beauty".

Caricatures
often exaggerate facial features to make a face more easily recognized in association with a pronounced portion of the face of the individual in question—for example, a caricature of Osama bin Laden might focus on his facial hair and nose; a caricature of George W. Bush might enlarge his ears to the size of an elephant's; a caricature of may pronounce his head and chin; and a caricature of might enlarge his lips. Exaggeration of memorable features helps people to recognize others when presented in a caricature form. information about caricatures . Edu.dudley.gov.uk. Retrieved on 2011-04-29.


Metaphor
By extension, anything which is the forward or world-facing part of a system which has internal structure is considered its "face", like the façade of a building. For example, a public relations or might be called the "face" of the organization he or she represents. "Face" is also used metaphorically in a sociological context to refer to reputation or standing in society, particularly Chinese society,: "The concept of face is, of course, Chinese in origin". and is spoken of as a resource which can be won or lost. Because of the association with individuality, the anonymous person is sometimes referred to as "faceless".
