Object permanence is a key concept in developmental psychology, described by Jean Piaget. It refers to a child’s ability to understand that an object continues to exist even when they can no longer see it.
An Understanding That Develops Gradually
Before around 8 months, a baby who can no longer see an object often acts as if it has disappeared. This lack of active searching is not a sign of disinterest, but a normal stage of cognitive development.
Between 8 and 12 months, a child begins to look for an object hidden under a cloth or behind a screen, a sign that their mental representation of the object is becoming established.
Peekaboo
This simple game, found in many cultures, naturally supports this stage. It allows the child to experience the disappearance and reappearance of a familiar face in a reassuring and playful setting.
Why This Stage Matters
Object permanence is linked to the development of working memory and to the child’s future ability to anticipate events. It also lays the foundation for understanding a parent’s temporary absence, which is important for emotional security.
Encouraging This Discovery in Everyday Life
No special equipment is necessary: a familiar object hidden under a cushion or blanket is enough. Free play on the floor, for example on a baby play mat, provides a stable, repeatable setting for this type of exploration.
