Roger is a playful 1-year-old. During his playtime, his father sometimes hides one of his toys to see if Roger realizes that the toy is missing. Roger begins a prompt search for the toy as soon as he notices that it is missing. According to Jean Piaget's theory of cognitive development, Roger appears to be in the sensorimotor stage.

It's when your child starts to realize the things and people, like you! making up their world exist even when they aren't interacting with them.
