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.
"Several studies have indicated that as many as 1 in 50 people may have developmental prosopagnosia," the NHS reports, meaning as many as 6.5 million people in the U.S. could have it, to varying ...
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]
These variants of visual agnosia include prosopagnosia (inability to recognize faces), pure word blindness (inability to recognize words, often called "agnosic alexia" or "pure alexia"), agnosias for colors (inability to differentiate colors), agnosias for the environment (inability to recognize landmarks or difficulty with spatial layout of an ...
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 fusiform gyrus, also known as the lateral occipitotemporal gyrus, [1] [2] is part of the temporal lobe and occipital lobe in Brodmann area 37. [3] The fusiform gyrus is located between the lingual gyrus and parahippocampal gyrus above, and the inferior temporal gyrus below. [4]
[2] In addition to describing the cases, Sacks comments on them, explains their pathophysiological background, discusses potential neuroscientific implications of such cases and occasionally makes reference to some psychological concepts, such as the soul, id, ego, and super-ego. Sacks dedicated the book to Leonard Shengold, M.D.
A difficulty in recognizing faces can be explained by prosopagnosia. Someone with prosopagnosia cannot identify the face but is still able to perceive age, gender, and emotional expression. [41] The brain region that specifies in facial recognition is the fusiform face area. Prosopagnosia can also be divided into apperceptive and associative ...
