Why do some songs get stuck in our heads? In this episode, our presenter Ginny Smith explores the psychology of earworms. Ginny hears about the possible evolutionary reasons for why we experience the phenomenon, learns what earworms can teach us about memory — and finds out how to get rid of them. Our guests, in order of appearance, are Kelly Jakubowski, assistant professor of music psychology at Durham University; Petr Janata, professor of psychology at the University of California, Davis; and Michael K. Scullin, associate professor of psychology and neuroscience at Baylor University. Episode credits: Presented and produced by Ginny Smith. Mixing and editing by Jeff Knowler.
