Imagine that you’re supposed to meet colleagues for dinner, only you can’t remember what their faces look like. For some, this is a reality, as people with face blindness or developmental prosopagnosia (DP) have severe difficulties recognizing faces, including those of family and friends, despite having no history of brain damage (e.g., brain trauma, head injuries). A new study finds that developmental prosopagnosia often occurs as a result of a neurobiological problem in the brain, which affects visual recognition broadly.
