Amir Levine, associate professor of psychiatry at Columbia University and co-author of Attached: The New Science of Adult Attachment and How It Can Help You Find—and Keep—Love, explains the origins and science behind attachment theory and how human bonding is a necessary element “from the moment we are born until we die.” 

As infants, humans’ bond between mother or caregiver is essential, what Levine calls “a necessary element in our thriving, just as much as food and water.” When those patterns of attachment are formed, they can also carry through into adulthood and impact subsequent bonds and attachments.

Attachment theory was pioneered by British psychiatrist and child development specialist John Bowlby, whose research included working with children displaced during The Blitz in WWII London. 

“What they noticed [was] even though they were able to give them food and shelter, because there were so many, they didn't pay much attention to engaging with them,” Levine explains. “A lot of these very young infants and kids failed to grow properly and develop.”
