Face Recognition

The purpose of this paper is to explain the processes associated with face recognition, identification and classification, the role of encoding and retrieval processes involved with long-term memory and how it affects face recognition, and identify two possible errors that can occur with face recognition.

Face perception is multifaceted, individuals are capable of gathering a continuous stream of social information, ranging from verbal and nonverbal communication. For humans, faces are the most significant for visual stimuli, a fact that becomes apparent in social settings—as a species we are constantly, almost obsessively, monitoring each other's faces, paying close attention to subtle details that can give some insight into the emotional state, level of engagement, or object of attention of our associates. Fluency with faces offers great social advantages, allowing one to glean aspects of another's internal thought processes and to predict their behavior. (Leopold, 2010). Explain the processes associated with face recognition, identification, and classification

Concept generally refer to the abstract notion of what that category represents in one’s mind.((Robinson-Riegler, 2008). The recognition of individual faces is in some ways the pinnacle of human visual performance. Because all faces have the same basic configural appearance (for example: two eyes above a nose and mouth, sometimes called the first-order configuration), individuals must be identified by subtle deviations from this prototypic pattern, sometimes referred to as second-order relational information or configuration .

To process facial identification an individual depend on the process of first-order relational information, the information about the parts of an object and how those parts relate to one another. For face recognition, this would involve an analysis of the person’s facial features and the relationship among those features. However, first-order relational information is not enough to recognize faces; simply noticing that two eyes are above the nose, which is above the mouth, may be enough for recognition that something is a face but doesn’t allow for recognition of who the face is. To recognize faces, we need second-order relational information. Second-order relational information involves comparing the first-order analysis to facial features of a “typical,” or “average,” face. This typical face is built up through experience and serves as an implicit standard against which we compare the faces we see. Inverting a face disrupts the encoding of second-order relational information

When we deal with information, we do so in steps. One way to think of this is to picture the process of acquiring, retaining, and using information as an activity called information processing Information comes from the outside world into the sensory registers in the human brain. This input consists of things perceived by our senses. We are not consciously aware of most of the things we perceive; we become aware of them only if we consciously direct our attention to them. When we do focus our attention on them, they are placed in our working memory. (Education, 2011)

Even when perceivers are presented with stimuli in suboptimal conditions, the face-processing system is still capable of extracting categorical knowledge in a rapid and accurate manner. Third, category activation is sensitive to the typicality of group members. In categorical thinking people identify with groups who they are familiar with. Analyze the role of encoding and retrieval processes involved with long-term memory and how this affects face recognition.

Early perceptual processes (and their associated products) also appear to play an important contributory role to the generation of categorical thinking. Categorization is a fundamental property of the brain. Categorical thinking streamlines most aspects of person perception, including...
