The idea
Object permanence is understanding that objects continue to exist when they cannot be seen, which Piaget placed at eight to twelve months.

A baby lifting a blanket to find a toy hidden underneath.

It arrives with goal-directed behaviour in the fourth substage. Later research found signs of it much earlier, around four months.
