Prosopagnosia /ˌprɒsəpæɡˈnoʊʒə/ (Greek: “prosopon” = “face”, “agnosia” = “not knowing”), also called face blindness, is a cognitive disorder of face perception where the ability to recognize faces is impaired, while other aspects of visual processing (e.g., object discrimination) and intellectual functioning (e.g., decision making) remain intact.
