Document Summary
Faces involve complicated processing: recognition involves between and within category judgment, recognition often happens at a semantic level serving the purpose of naming a person. Faces are essential to many aspects of social behaviour: evolutionary significance in group vs. out group; friend vs. threat, newborns track normal faces more than scrambled faces, decoding intention and behaviour. Eg. gender and ethnicity: semantic (specific) Evidence to believe that faces are special: viewpoint dependency. Face recognition drops with image inversion no such observation with other objects. Face recognition drops with reversed contrast no such observation with other objects. Caricatured faces are often more identifiable than veridical photographs. Certain aspects of faces are crucial for identifying them: face recognition after effects indicate that the face norm is adaptable. Face recognition does not depend on retinal positions or on image size. Recognition depends on external features of the person contextual information aids recognition.
