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]
These individuals experience difficulty with learning routes. This form of agnosia is often associated with lesions to the bilateral or right hemisphere posterior regions. It is also associated with prosopagnosia and Parkinson's disease. [3] Finger agnosia: Is the inability to distinguish the fingers on the hand.
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.
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.
Combing early studies, the traditional symptoms of CWS centered on visual irreminiscence (aphantasia), prosopagnosia, and topographic agnosia.However, due to significant differences in the observations of Charcot and Wilbrand's case work, this syndrome bridged the entire loss of dreaming, whether it be due to the isolated inability of the brain to produce images while asleep as Charcot had ...
Prosopometamorphopsia (PMO [1]), also known as demon face syndrome, [2] is a visual disorder characterized by altered perceptions of faces. In the perception of a person with the disorder, facial features are distorted in a variety of ways including drooping, swelling, discoloration, and shifts of position.
