Developmental psychologists used to believe that for infants, ‘out of sight is out of mind.’ We now know better! Very young infants can think about objects—even hidden ones—in some sophisticated ways. Still, they have a lot to learn, and their memories for detail remain fragile. Recently, we’ve discovered that infants learn best about objects when they are listening to people talk about them. In our current work, we are delving deeper to discover: does language boost infants’ attention to, and memory for, details about objects? Might infants’ love of language also help them remember and reason about the objects in their world?
