Sensorimotor Stage of Cognitive Development
Object Permanence:
This is one of the most important accomplishments at this stage. It is a child's understanding that objects continue to exist even though they cannot be seen or heard. If you think about a game of peek-a-boo, a young infant will believe that the other person or object has actually disapeared and will act shocked when the object or person reappears. Older infants who understand object permanence will realize that the person or object continues to exist even when unseen.
