We may often feel that infants forget objects when it is taken away from their line of sight.
Though this is partly true, that babies may not remember the details of objects, researchers found that their brains still have built-in "pointers" which assist in retaining the idea about the existence of the object even though it might have moved away from their line of sight.
Infact, babies may not be able to recall the shapes of hidden objects but they are surprised when the objects have vanished from their sight.
"Our results seem to indicate that the brain has a set of 'pointers' that it uses to pick out the things in the world that we need to keep track of. The pointer itself doesn't give us any information about what it is pointing to, but it does tell us something is there. Infants use this sense to keep track of objects without having to remember what those objects are. In short, they retained an inkling of the object," said researchers.
