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]
Individuals with prosopagnosia know that they are looking at faces, but cannot recognize people by the sight of their face, even people whom they know well. [ 6 ] Simultagnosia , an inability to recognize multiple objects in a scene, including distinct objects within a spatial layout and distinguishing between "local" objects and "global ...
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]
When those with prosopagnosia view faces, the fusiform gyrus (a facial recognition area of the brain) activates differently to how it would in someone without the condition. [27] Additionally, non-facial object recognition areas (such as the ventral occipitotemporal extrastriate cortex ) are activated when viewing faces, suggesting that faces ...
[1] Only patients who have both factor 1 (impaired facial processing or mirror agnosia) and factor 2 (cranial damage to the right hemisphere) will develop the mirrored-self misidentification delusion. [2] Patients with impaired facial processing who do not have mirrored-self misidentification have prosopagnosia. [13]
