A 10-month old infant learns about the limits of support by placing a ball on a platform and then carefully moving it to the edge to watch it fall. She focuses her attention and organizes her behavior in a manner that makes the game possible. She searches for a ball close enough to reach, grabs the ball, puts it on the top of the platform, gently moves it to the edge, pauses it there, and then one more slight move makes it fall. Once she slips and bumps her head but recovers quickly. She puts her game ‘on hold’ to listen to a conversation. Her attention is temporarily diverted, but she leaves some mental space for the game. She even resists the exciting bouncing action of a ball and picks up the game where she left off. Having these two levels of attention supports the child’s regulation of her actions toward a goal.
