Fifteen years ago, psychologists Barbara Rogoff and Maricela Correa-Chavez ran a simple experiment. They wanted to see how well kids pay attention — even if they don't have to.
They would bring two kids, between the ages 5 to 11, into a room and have them sit at two tables.
Then they had a research assistant teach one of the kids how to assemble a toy.
The other kid was told to wait. Rogoff says they would tell the second child, "You can sit over here, and in a few minutes you'll have a turn to make this origami jumping mouse," — a different task altogether.
