Object permanence is "the understanding that objects continue to exist even when we do not see or hear them" (Kalat and Shiota, 2007, p.88).
Baby plays with disappearing ball
Example: http://www.youtube.com/watch?v=rJk5ociUGvY Application: This nine month baby shows how his toy continues to exist even after he does not see it. He keeps putting the ball through the hole in the wooden box and he sees it disappear. Once his mother pulls the box out he sees how it suddenly appear and continues to play with it. The baby eventually understands that if he pulls the wooden box out he can get the ball out and continue playing with it. Just because he does not see the ball once it is in the box it does not mean it does not exist.
