There is evidence of specific impairments that uniquely influence the recognition of faces as well as the recognition of stimuli, such as objects, cars, and animals. Many people experience difficulty in other aspects of facial processing, such as estimating their age or gender, tracking eye movements, or just generally navigating their lives. An example supporting these listed statements indicates that patients with prosopagnosia could identify objects involved in their daily lives. However, they could only identify their family members by conversing with them, because they could recognize voices (Meadows, 1974). Say no to plagiarism.

Acquired prosopagnosia is subdivided into apperceptive and associative prosopagnosia. People with apperceptive prosopagnosia lack the ability to differentiate between familiar and unfamiliar faces. They also have difficulty identifying facial emotions (Biotti, Cook & Cortex, 2016). However, they may be able to identify people from cues other than the face, such as their dress, hair, skin tone, or voice (Barton, Cherkasova, Press, Intrillgator & O'Connor , 2004). Associative prosopagnosia is used to describe people with sparing disorders. perceptual processes but deficits in linking early processes of facial perception and the semantic information we have about people in our memories. This means that people with this form of prosopagnosia may be able to make sense of facial information, but may not be able to connect other information about themselves, such as their name and age (Gainotti and Marra, 2011).Congenital prosopagnosia (CP) It is also called developmental prosopagnosia. This form of prosopagnosia occurs in early childhood, lasts throughout life, and in the presence of intact sensory functioning. CP patients can recognize a face but are unable to recognize that face. Unlike PA, CP may go unnoticed because the person does not have a basis of comparison for normal face processing skills (Behrmann and Avidan, 2005). Finally, people with CP have a lifetime to adapt to this deficit, so they are more able to use features such as hairline or eyebrows for identification. Signs and Symptoms People who suffer from prosopagnosia have several signs and symptoms. Their list is as follows: They are unable to recognize familiar people, including family members. They are shy. They have difficulty making friends. They seem introverted at school, but they are confident when they are at home. Causes: Previously it was I thought that very few people suffered from prosopagnosia. The disease has traditionally been studied in people who acquire the disease following neurological injury (usually following a stroke or head trauma), and a handful of case studies have been reported in the literature. in the 20th..
