Researchers Bring Together Robot and Baby Studies to Understand Why Infants Smile
University of California San DiegoWhy do babies smile when they interact with their parents? Could their smiles have a purpose? In the Sept. 23 issue of PLOS ONE, a team of computer scientists, roboticists and developmental psychologists confirm what most parents already suspect: when babies smile, they do so with a purpose—to make the person they interact with smile in return. To verify their findings, researchers programmed a toddler-like robot to behave like the babies they studied and had the robot interact with undergraduate students.
