The new Laboratory for Child Development, which opened at Johns Hopkins University in the fall, will explore everything from how infants keep track of objects to whether babies and children are logical and rational when making decisions.

"We investigate how infants and young children perceive and reason about the world around them," says Lisa Feigenson, PhD, assistant professor of psychological and brain sciences and co-director of the lab. "We have discovered that, in many ways, children know much more than people once thought they did. But in other ways, children perceive the world quite differently than adults do."

The lab's first few projects include how infants and young children track and reason about moving or hidden objects; how children learn words for new objects and actions; and how children understand numbers prior to formal mathematical education.

Feigenson's co-director, Justin Halberda, PhD, assistant professor of psychological and brain sciences, is also her husband. The couple came to Johns Hopkins from Harvard University to set up and run the new lab.
