1. prosopagnosianoun

   A form of visual agnosia characterised by difficulty with face recognition despite intact low-level visual processing. Also known as PA.

2. Etymology: Apparently derived from the title of a 1947 paper by neurologist Joachim Bodamer describing the condition, titled Die Prosop-Agnosie, derived from and αγνωσία.

1. Prosopagnosia

   Prosopagnosia (from Greek prósōpon, meaning "face", and agnōsía, meaning "non-knowledge"), more commonly known as face blindness, 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. The term originally referred to a condition following acute brain damage (acquired prosopagnosia), but a congenital or developmental form of the disorder also exists, with a prevalence of 2.5%. The brain area usually associated with prosopagnosia is the fusiform gyrus, which activates specifically in response to faces. The functionality of the fusiform gyrus allows most people to recognize faces in more detail than they do similarly complex inanimate objects. For those with prosopagnosia, the method for recognizing faces depends on the less sensitive object-recognition system. The right hemisphere fusiform gyrus is more often involved in familiar face recognition than the left. It remains unclear whether the fusiform gyrus is specific for the recognition of human faces or if it is also involved in highly trained visual stimuli. Acquired prosopagnosia results from occipito-temporal lobe damage and is most often found in adults. It is subdivided into apperceptive and associative prosopagnosia. In congenital prosopagnosia, the individual never adequately develops the ability to recognize faces.Though there have been several attempts at remediation, no therapies have demonstrated lasting improvements across a group of prosopagnosics. Prosopagnosics often learn to use "piecemeal" or "feature-by-feature" recognition strategies. This may involve secondary clues such as clothing, gait, hair color, skin color, body shape, and voice. Because the face seems to function as an important identifying feature in memory, it can also be difficult for people with this condition to keep track of information about people, and socialize normally with others. Prosopagnosia has also been associated with other disorders that are associated with nearby brain areas: left hemianopsia (loss of vision from left side of space, associated with damage to the right occipital lobe), achromatopsia (a deficit in color perception often associated with unilateral or bilateral lesions in the temporo-occipital junction) and topographical disorientation (a loss of environmental familiarity and difficulties in using landmarks, associated with lesions in the posterior part of the parahippocampal gyrus and anterior part of the lingual gyrus of the right hemisphere).The opposite of prosopagnosia is the skill of superior face recognition ability. People with this ability are called "super recognizers".In one study of students of east-Asian ethnicity, males were found to be significantly poorer at face-recognition.

1. Prosopagnosia

   Prosopagnosia, also called face blindness, is a disorder of face perception where the ability to recognize faces is impaired, while other aspects of visual processing and intellectual functioning remain intact. The term originally referred to a condition following acute brain damage, but a congenital or developmental form of the disorder also exists, which may affect up to 2.5% of the population. The specific brain area usually associated with prosopagnosia is the fusiform gyrus, which activates specifically in response to faces. Thanks to this specialization, most people recognize faces much more effectively than they do similarly complex inanimate objects. For those with prosopagnosia, the ability to recognize faces depends on the less-sensitive object recognition system. Though there have been several attempts at remediation, no therapies have demonstrated lasting real-world improvements across a group of prosopagnosics. Prosopagnosics often learn to use 'piecemeal' or 'feature by feature' recognition strategies. This may involve secondary clues such as clothing, gait, hair color, body shape, and voice. Because the face seems to function as an important identifying feature in memory, it can also be difficult for people with this condition to keep track of information about people, and socialize normally with others. Prosopagnosia has also been associated with other disorders that are associated with nearby brain areas: left hemianopsia, achromatopsia and topographical disorientation.

1. Prosopagnosia

   The inability to recognize a familiar face or to learn to recognize new faces. This visual agnosia is most often associated with lesions involving the junctional regions between the temporal and occipital lobes. The majority of cases are associated with bilateral lesions, however unilateral damage to the right occipito-temporal cortex has also been associated with this condition. (From Cortex 1995 Jun;31(2):317-29)

Examples of prosopagnosia in a Sentence

1. Brad Duchaine:

   Differences in face recognition ability in the typical population result primarily from genetic differences, developmental prosopagnosia (DP) often runs in families, so it is likely that genetic factors play a big role in the emergence of most cases of DP. However, we haven't identified any of the genes involved in face recognition yet.

2. Brad Duchaine:

   People with prosopagnosia experience elevated anxiety due to the many problems the disorder creates for social interaction.
