Answer to Question 2
Object permanence is the ability of a child to know that an object exists even when it is hidden. To test this ability, show an object to the child and then hide it under a blanket or behind a screen. Determine whether the infant seeks the object by looking with its eyes or searching for it with its hands. Younger infants will have a limited ability to search with its hands, so another technique is available for measuring this ability. One can show an object, hide it with a screen, remove the object from behind the screen and determine whether the infant shows surprise at the object's absence when the screen is removed.
