Prosopagnosia (also known as face blindness) is a condition that refers to the inability to recognize a face that you've seen before and should be able to recall. Those affected can read emotions in a face, but identifying the person is next to impossible without certain cues.

Previously, much of the research into prosopagnosia has focused on adults. Dr. Al Yonas and Sherryse Corrow of the University of Minnesota's Institute of Child Development recently began working to better identify this disorder in children, with the hopes of eventually developing better treatment methods.
