Prosopagnosia, [2] also known as face blindness, [3] is a cognitive disorder of face perception in which the ability to recognize familiar faces, including one's own face (self-recognition), is impaired, while other aspects of visual processing (e.g., object discrimination) and intellectual functioning (e.g., decision-making) remain intact.
Prosopagnosia is a disorder which causes the inability to use overt facial recognition. [9] While people suffering from prosopagnosia often cannot identify whose face they are looking at they usually show signs of covert recognition. This can be seen in their ability to accurately guess information during forced choice tasks. [2]
Nakayama is known for his work on prosopagnosia (an inability to recognize faces) and super recognisers (people with significantly better-than-average face recognition ability). [ 2 ] [ 3 ] [ 4 ] A notable contribution is from his work on surface processing by the human visual system.
A specific form of associative visual agnosia is known as prosopagnosia. Prosopagnosia is the inability to recognize faces. For example, these individuals have difficulty recognizing friends, family and coworkers. [22] However, individuals with prosopagnosia can recognize all other types of visual stimuli. [23]
The study of prosopagnosia (an impairment in recognizing faces that is usually caused by brain injury) has been particularly helpful in understanding how normal face perception might work. Individuals with prosopagnosia may differ in their abilities to understand faces, and it has been the investigation of these differences which has suggested ...
The individual essays in this book include: Part One: "The Man Who Mistook His Wife for a Hat", about Dr. P., a singer and music teacher who has visual agnosia.He perceives separate features of objects, but cannot correctly identify them or the whole objects that they are part of.
In this way, it is very easily mistaken as prosopagnosia, which is an inability to perceive or recognize faces. Prosopagnosia is a deficit that occurs earlier in the neural circuit while the facial stimuli is being processed, whereas prosopamnesia takes effect when the brain attempts to encode the processed facial stimuli into memory.
