The ability to recognize faces naturally varies significantly among individuals. At one end of this spectrum of ability are individuals with weak face memory, while at the other end are 'super-recognizers' who possess exceptional face recognition skills. Individuals with developmental prosopagnosia are situated at the lower end of this spectrum, yet are still considered part of the natural variation in face recognition ability. Acquired prosopagnosia (face blindness), on the other hand, is a neurological disorder typically resulting from brain damage, characterized by the loss of face recognition ability, and is distinct from natural variability.
