#452 Face Recognition and Identity
This week we deep dive into the science of how we recognize faces and why some of us are better -- or worse -- at this than others. We talk with Brad Duchaine, Professor of Psychology at Dartmouth College, about both super recognizers and face blindness. And we speak with Matteo Martini, Psychology Lecturer at the University of East London, about a study looking at twins who have difficulty telling which one of them a photo was of.
