Prosopagnosia or Face Blindness

Prosopagnosia, which is also known as ‘face blindness’, is the inability to recognize familiar faces. There are evidence that there are particular impairments that only influence face recognition as properly as stimuli recognition, such as objects, automobiles, and animals. A lot of people encounter difficulty in other elements of face processing, such as estimating one’s age or gender, or tracking eye movements or just common navigation in one’s life. An instance supporting these listed claims states that prosopagnosia patients could identify objects that requires in one’s everyday life. However, they could only identify their household members by conversing with them as they could recognize voices(Meadows, 1974).


  1. Acquired Prosopagnosia (AP)Acquired prosopagnosia is a outcome of occipito-temporal lobe damage and is most frequently diagnosed in adults. Acquired prosopagnosia is additional subdivided into apperceptive and associative prosopagnosia. Men and women who are diagnosed with Apperceptive Prosopagnosia do not have the capacity to differentiate familiar from unfamiliar faces. They also struggle with identifying facial feelings (Biotti, Cook & Cortex, 2016). Nevertheless, they could be able to determine people from non-face clues such as their dressing, hair, skin tone or voice (Barton, Cherkasova, Press, Intrillgator & O’Connor, 2004).

  2. Associative Prosopagnosia is utilised to describe people with spared perceptual processes but deficits in linking early facial perception processes and the semantic details we have of individuals in our memories. This means that folks with this form of prosopagnosia may be in a position to make sense of facial data, but might not be able to hyperlink any other information about them such as their name and age (Gainotti & Marra, 2011).
  3. Congenital Prosopagnosia (CP)

  4. It is also known as Developmental Prosopagnosia. This form of prosopagnosia happens in one’s early childhood ,lasting for a lifetime and in the presence of intact and sensory functioning. CP patients can acknowledge a face but are unable to recognise that face. Unlike AP, it is possible for CP to go undetected as the particular person does not have a basis of comparison for typical face processing abilities (Behrmann & Avidan, 2005). Lastly, individuals with CP have a lifetime to adapt to this deficit so consequently, they are much better at utilizing features such as hairline or eyebrows for identification.

Indicators and Symptoms

Individuals who endure from prosopagnosia display a number of signs and symptoms. The list of them are as beneath:
  • They are unable to recognize familiar men and women, which consist of family members members
  • They are shy
  • They have a tough time in creating close friends
  • They look to be introverts in school, but they are confident when they are at residence.


Previously, it was believed that really few folks expertise prosopagnosia. The situation has traditionally been studied in folks who acquire the disorder following neurological damage (usually from stroke or head injury), and a handful of case studies were reported in the literature in the 20th century. Nonetheless, it has recently turn into clear that a lot of much more people have prosopagnosia without experiencing neurological harm. This form of the disorder is generally referred to as “developmental” or “congenital” prosopagnosia, and these folks simply fail to create normal face processing skills regardless of typical intellectual and perceptual functions. Men and women with developmental prosopagnosia seem to have had face recognition difficulties for most of their lives, and perhaps even given that birth. Current proof suggests there may be a genetic contribution to the situation, and several individuals report at least one particular initial-degree relative who also experiences face recognition difficulties.


Some people cope nicely with their face recognition issues, and even develop elaborate compensatory mechanisms to assist them function successfully in every day life. For others, even so, the situation has a a lot greater influence on day-to-day functioning. Some people avoid social interactions, encounter problems with interpersonal relationships or harm to their profession, and even report episodes of depression. In extreme instances, people with prosopagnosia develop social anxiousness disorder, characterized by fear and avoidance of social situations that could lead to embarrassment.


There is no fixed remedy The focus of any remedy should be to aid the person with prosopagnosia develop compensatory approaches. Adults who have the condition as a result of stroke or brain trauma can be retrained to use other clues to recognize folks.
