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. [5] [6] Nakayama received his BA from Haverford College and PhD ...
One disorder often seen alongside cerebral achromatopsia is prosopagnosia, the inability to recall or recognize faces. The correlation is still the subject of ongoing research, but the most telltale clue in this association is the close proximity of brain lesions seen in prosopagnosics and those with cerebral achromatopsia without prosopagnosia ...
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 ...
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 ...
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]
Similar research regarding prosopagnosia has determined that the FFA is essential to the recognition of unique faces. [27] [28] However, these patients are capable of recognizing the same people normally by other means, such as voice. Studies involving language characters have also been conducted in order to ascertain the role of the FFA in ...
