Face perception is the mind's ability to recognize and register another visage. It plays a significant role in social interactions. Through it we distinguish the familiar from the strange and formulate nuanced readings of people's moods and characters. However, controversy surrounds the process of face perception. Psychologists argue that it involves a series of stages: Individuals recognize physical features, make broad inferences regarding gender and age, and finally recall meaningful information regarding the face they perceive, such as a name. Cognitive neuroscientists, on the other hand, posit the idea that face perception works through analogy: The mind has an inherent ability to connect similar objects. While the exact process of face perception is still unclear, evidence suggests that it involves a specific set of skills and that the fusiform gyrus, a part of the brain, is necessary for it to occur.
