IndexWhat is prosopagnosia?TypesSigns and symptomsCausesEffectsTreatmentWhat is prosopagnosia?Prosopagnosia, also known as "face blindness", is the inability to recognize familiar faces. There is evidence that there are particular impairments that only affect the recognition of faces and the recognition of stimuli, such as objects, cars and animals. Many people have difficulty with other aspects of face processing, such as estimating their age or gender, or tracking eye movements, or just general navigation of their lives. An example to support these listed claims states that patients with prosopagnosia could identify objects that they engage in their daily life. However, they could only identify their family members by conversing with them as they could recognize voices (Meadows, 1974). Say no to plagiarism.

Acquired prosopagnosia is further divided into apperceptive and associative prosopagnosia. People diagnosed with apperceptive prosopagnosia lack the ability to distinguish familiar from unfamiliar faces. They also have difficulty identifying facial emotions (Biotti, Cook & Cortex, 2016). However, they may be able to identify people from non-face cues such as clothing, hair, skin tone, or voice (Barton, Cherkasova, Press, Intrillgator & O'Connor, 2004). Associative prosopagnosia is used to describe people with perceptual processes but deficits in connecting early facial perception processes and the semantic information we have about people in our memory. 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 name and age (Gainotti & Marra, 2011). Congenital Prosopagnosia (CP) It is also known as Developmental Prosopagnosia. This form of prosopagnosia occurs in early childhood, lasts throughout life, and in the presence of intact sensory functioning. Patients with CP can recognize a face but are unable to recognize that face. Unlike PA, CP may not be detected because the person has no basis of comparison for normal face processing abilities (Behrmann & Avidan, 2005). Finally, people with CP have their whole lives to adapt to this deficit, so they are better at using features such as hairline or eyebrows for identification. Signs and Symptoms People suffering from prosopagnosia show various signs and symptoms. The list of them 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 are confident when they are at home. Causes Previously, I thought that very few people experienced prosopagnosia. The condition has traditionally been studied in individuals who acquire the disorder following neurological damage (typically due to stroke or head trauma), and a handful of case studies have been reported in the literature in the 20th century. However, it has recently become clear that many more people suffer from prosopagnosia without suffering neurological damage. This form of the disorder is commonly referred to as "developmental" or "congenital" prosopagnosia, and these people simply fail to develop normal facial processing abilities despite normal intellectual and perceptual functions.
