Current reflections on Prosopagnosia: Is Prosopagnosia limited to the recognition of faces

Humans have traditionally lived in tiny groups of less than a hundred people throughout our evolutionary history. Our face recognition abilities, on the other hand, appear to enable us to recognize a large number of people, possibly thousands. Even though modern society offers access to a lot of faces, nobody knows how many people know. Prosopagnosia (from Greek próspon, meaning "face," and Agnes, meaning "non-knowledge"), also known as face blindness, is a face perception disorder where the ability to identify familiar faces, including their face (self-recognition), is damaged while other facets of visual processing, for example, object discrimination and cognitive functioning (e.g., decision-making) are unaffected.
