Developmental prosopagnosia (DP), also called congenital prosopagnosia (CP), is a face-recognition deficit that is lifelong, manifesting in early childhood, and that cannot be attributed to acquired brain damage. While developmental prosopagnosia begins early in life, many people do not realize that they have DP until later in their adult lives.
There are two different varieties of prosopagnosia: Developmental prosopagnosia, meaning a person has developed the condition without having suffered any injury to their brains, and acquired ...
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]
Bruce & Young Model of Face Recognition, 1986. One of the most widely accepted theories of face perception argues that understanding faces involves several stages: [7] from basic perceptual manipulations on the sensory information to derive details about the person (such as age, gender or attractiveness), to being able to recall meaningful details such as their name and any relevant past ...
Prosopagnosia is a condition marked by an inability to recognize faces. [26] When those with prosopagnosia view faces, the fusiform gyrus (a facial recognition area of the brain) activates differently to how it would in someone without the condition. [ 27 ]
Prosopagnosia is an inability to identify faces and face-like objects. This represents a failure to encode incoming visual information. Neurological studies indicate that prosopagnosia is associated with bilateral lesions of the central visual system, primarily located in the medial occipitotemporal region. [16]
A difficulty in recognizing faces can be explained by prosopagnosia. Someone with prosopagnosia cannot identify the face but is still able to perceive age, gender, and emotional expression. [41] The brain region that specifies in facial recognition is the fusiform face area. Prosopagnosia can also be divided into apperceptive and associative ...
Similar research regarding prosopagnosia has determined that the FFA is essential to the recognition of unique faces. [27] [28] However, these patients are capable of recognizing the same people normally by other means, such as voice. Studies involving language characters have also been conducted in order to ascertain the role of the FFA in ...
