Object Permanence Milestone – Importance and Stages

Object Permanence Milestone

As adults, we understand that objects exist even if we cannot see or hear them, but babies do not perceive the objects in a similar manner.  For babies, whatever is not seen or heard ceases to exit. However, it is an important milestone for babies to understand and learn that even if they can’t see certain things, they are still there and this is what object permanence is all about.



What is Object Permanence

Object permanence is when your mind knows that even if you cannot see or hear something, it is there. When your baby is one month old, if you hide something from your baby or put it away, your baby thinks that it does not exist any longer, this is because his hearing and vision are still in a nascent stage. However, soon enough that is around 4 to 7 months of age, your baby understands that if something is out of sight or mind, it is still there.





Why is Object Permanence an Important Milestone

Object permanence is an important developmental milestone. Object permanence helps your baby to understand the world around him; he also learns to expect what may happen next. For instance, if you hide your baby’s toy under the blanket, he will look for it by lifting up the blanket. This gives your baby an idea that it is okay for things to disappear sometimes or give up things because he can get it back later. Lack of object permanence in the earlier months may frighten your baby. If you go into another room for some time, he may get frightened thinking that you have disappeared, as for babies what they can’t see, no longer exists. However, as your baby learns about object permanence, he learns that people exist, which means that even if they leave, they are there. And thus now when you come and go, he will be fine with it.

When Does a Child Develop Object Permanence

Here we shall discuss the stages of object permanence or how a child achieves this milestone:




1. Birth to 1 Month: Reflexes

In the neonatal stage, your baby understands and explores the world around him through his reflexes. Your baby relies on his reflexes such as sucking, startling or rooting in order to interact with the world around him. However, at this age, your baby has no idea of object permanence, but he is exposed to visual stimuli that means that he may detect movements, which is an important milestone at this stage.

2. 1 to 4 Months: Primary Circular Reaction

Your baby may respond to familiar images, objects or activities, though it may only be for a few seconds. Also, your baby may keep looking at an object or follow an object for some time. Around this age, your baby’s attention is more intentional rather than reflexive.





3. 4 to 8 Months: Secondary Circular Reaction

Around this age, a baby pays more heed to the world around him and may perform actions to generate a response. During this stage, your baby starts understanding about object permanence and may look for partially hidden things but may not look for completely hidden things. Your baby may take visual clues and comprehend about objects, but he is yet to understand more about object permanence.

4. 8 to 12 Months: Greater Sense of Exploration

Your baby is able to retrieve objects that you may hide from him, though it may seem a small task, it is a major cognitive development milestone. Your baby explores things and is more goal-oriented, which means his desire to look out for things is more intentional. However, your baby may find an object that you hide at a usual place and not understand that he can find the object at a different place.




5. 12 to 18 Months: Tertiary Circular Reaction

Around this age, your baby may be able to find an object that is within his visual field. This means that he may only look for an object that you may hide within his visual field and not beyond that. Your baby may do things to gain attention from other, which is a significant milestone for your little one.

6. 18 to 24 Months of Age: Emergence of Object Permanence

Around this age, your baby has a fair idea of what object permanence is. Your baby develops a mental representation of objects, which means that he may be able to find hidden objects too. By this time, your baby will be able to imagine a thing that he cannot see and thus he is able to understand about object permanence.

How Piaget Measured Object Permanence in Infants

Before the theory of object permanence was suggested, it was believed that cognitive development happens passively, that is it just happens. Jean Piaget, a psychologist, believed that cognitive development in babies and children is more vast and complex than it is understood to be. As per Piaget’s theory, babies do not just sit and wait for things to happen, rather they make constant efforts to understand new information, apply it to their existing concepts, and create their own representation of various objects around them. In simple words, babies understand and perceive various things around them by making use of their motor skills such as vision, touch, movement, and taste.

At first, babies have no clue of the world around them, and they believe and understand, only what they can see. Therefore, mental representation of various objects becomes very important in order to understand that objects continue to exists, even when the eyes cannot see them.




Jean Piaget calls these mental representations as schemas, which means knowledge of things in the world. For instance, a baby may have a schema for breast milk or bottle. As your baby grows, his schemas multiply and may become more and more complex. However, by the process of accommodating and assimilating, children tend to develop various new categories by increasing their already existing categories and may change their current schemas.

Object Permanence Games

Babies learn soon through fun and playful ways, and therefore as parents; you do not have to slog your way out to teach your baby about object permanence. The best way to help your baby learn any skill is by spending some quality time with your baby. It is only through interaction and experiences with parents and loved ones that may help your baby to master various skills and enhance his learning. You may buy object permanence toys or play the following games with your baby:





1. Play Leave and Return

This a good game that you can play with your little one. You can simply go from the room, leaving your baby with your partner or a caretaker and return in a while. It is a great way of teaching your baby that even when he cannot see you, you are there. Also, object permanence is not just about visual perception. You can even call out your baby from the other room to let him that you are there, even if you are not visible.

2. Play Peek-a-boo

Peek-a-boo is one of the best games of giving a hang of object permanence to your baby. You may play this game with your baby if he is anywhere between 6 to 12 months of age, as by this age he is getting the idea of object permanence. You may hide behind a curtain or a door and show your face to the baby and then hide again. Your baby may be able to understand that if you are not seen, you are still there hiding behind the curtain.

3. Hide Your Baby’s Favourite Toy

You can take your baby’s favourite toy and hide it under the blanket for a while and then take it out. You can also leave a small part of it visible so that your baby can find it out on his own. You can make this game more interesting and challenging as your baby grows, by hiding most of the toy and making a smaller part visible. Alternatively, you can take the toy and hide it behind you and bring it in front of your baby.

The above-mentioned games are a fun way to make sure that your baby understands about object permanence. However, not all babies are alike, where some babies may enjoy playing such games, others may panic at the sheer thought of your disappearance. It is recommended that you handle the situation accordingly, if your baby is not okay, skip playing such games for some time.
