Why do we feel a romantic connection with one person over another? Why do mothers so quickly bond with their newborn babies? Why do we feel so much for our pets? This hour, we explore the science of attachment with psychiatrist and neuroscientist Dr. Amir Levine.

Levine is the author of Attached, which, a decade later is still a wildly popular book. He’ll explain the different attachment styles, what goes on in our brains when we feel that connection, and ways to strengthen our own relationships.
