Face Recognition Paper

Face recognition develops slowly throughout one’s life. Recognizing a face can be a difficult for the individual and also for the brain system that processes it. The complexity of recognizing individual faces can be a difficult task at times. Recognizing faces also includes looking at an individual’s emotional expression and then being able to take that information and processing it. This can be more complicated because facial recognition also includes the processing of emotions and emotional content. The brain can easily recognize a face without encountering any complications.
Facial identification is essential for recognition of persons in the social context and for recognition of members within our

The amygdala processes emotional expression and not the physical aspects of a face. Most neuroanatomical substrates for facial processing are perfused by the middle cerebral artery. Therefore, facial processing has been studied using measurements of cerebral blood flow velocity in the middle cerebral arteries bilaterally. During facial recognition tasks, greater changes in the right middle cerebral artery than the left have been observed (Argumosa, M. A., 2010).
Facial identification is much simpler when faces are upright as opposed to inverted. Facial inversion has a disruptive effect on the recognition of faces. Identifying an inverted object takes more time to process than an inverted face. A person at any age may not recognize someone they have met before or known for a long period of time. People change over the years and even a person with a sharp memory may not recognize someone they have known for many years.
Other behavioral phenomena have been taken to indicate coding within a perceptual face-space, “defined as a multidimensional space in which each individual face is coded as a point by its value on underlying dimensions describing different aspects of facial structure, and for which the average face lies at the center of the space” (Valentine, 1991). These phenomena include: distinctiveness effects, in which performance is better for distinctive faces than typical faces on old-new recognition tasks,
