Some evidence suggests that prosopagnosia may not be specific to faces, but rather it may be attributable to a general inability to recognize parts of faces, distinguish among similar members of complex classes of visual stimuli, recognize cows and birds, or recognize specific names of faces.

The inability to recognize people by their faces is a troublesome problem. It can be caused by trauma, or it may be inborn. Watch this video (http://openstaxcollege.org/ I/faces) to learn more about a person who lost the ability to recognize faces as the result of an injury. She cannot recognize the faces of close family members or herself. What other information can a person suffering from prosopagnosia use to figure out whom they are seeing?
Which of the following statements most accurately describes the deficits of someone with prosopagnosia? "I have a lot of trouble recognizing when a person is happy versus when a person is sad." "I can only recognize the faces of my closest family members." "I see faces, but I can never be sure of the identity of a person based on his or her face." "I try to describe what I see, but I have great difficulty recognizing objects when looking at them." A region of the right hemisphere shows heightened activity levels when a person perceives upright faces. prefrontal cortex fusiform gyrus hippocampus hypothalamus
