Thinking still tends to be very concrete, but children become much more logical and sophisticated in their thinking during this stage of development.

While this is an important stage in and of itself, it also serves as an important transition between earlierstages of developmentand the coming stage where kids will learn how to think more abstractly and hypothetically.

Important things that happen in the concrete operational stage include a great understanding of logic, reversibility, and conservation. Children also become less egocentric during this stage.

Kids at this age become more logical about concrete and specific things, but they still struggle withabstract ideas.

Logic in the Concrete Operational Stage

Piagetdetermined that children in the concrete operational stage were fairly good at the use of inductive logic (inductive reasoning).Inductive logic involves going from a specific experience to a general principle.

An example of inductive logic would be noticing that every time you are around a cat, you have itchy eyes, a runny nose, and a swollen throat. You might then reason from that experience that you are allergic to cats.

Concrete operational stage of development

On the other hand, children at this age have difficulty using deductive logic, which involves using a general principle to determine the outcome of a specific event. For example, a child might learn that A=B, and B=C, but might still struggle to understand that A=C.

Reversibility in the Concrete Operational Stage

One important development in this stage is an understanding of reversibility or awareness that actions can be reversed.An example of this is being able to reverse the order of relationships between mental categories.

An example of reversibility is that a child might be able to recognize that his or her dog is a Labrador, that a Labrador is a dog, and that a dog is an animal.

Reversibility is an important step toward more advanced thinking, although at this stage it only applies to concrete situations.

Conservation in the Concrete Operational Stage

Another key development at this stage is the understanding that when something changes in shape or appearance it is still the same, a concept known as conservation.

Kids at this stage understand that if you break a candy bar up into smaller pieces it is still the same amount as when the candy was whole. This is a contrast to younger children who often believe that pouring the same amount of liquid into two cups means that there is more.

For example, imagine that you have two candy bars of the exact same size. You break one candy bar up into two equally sized pieces and the other candy bar up into four smaller but equally sized sections.

A child who is in the concrete operational stage will understand that both candy bars are still the same amount, whereas a younger child will believe that the candy bar that has more pieces is larger than the one with only two pieces.

One of the key characteristics of the concrete-operational stage is the ability to focus on many parts of a problem.

While kids in thepreoperational stage of developmenttend to focus on just one aspect of a situation or problem, those in the concrete operational stage are able to engage in what is known as “decentration.” They are able to concentrate on many aspects of a situation at the same time, which plays a critical role in the understanding of conservation.

Egocentrism in the Concrete Operational Stage

In Piaget’s Three-Mountain Task, for example, children in the concrete operational stage can describe how a mountain scene would look to an observer seated opposite them.

In other words, kids are not only able to start thinking about how other people view and experience the world, they even start to use this type of information when making decisions or solving problems.

While kids at earlier stages of development are egocentric, those in the concrete operational stage become more socio-centric.

In other words, they are able to understand that other people have their own thoughts. Kids at this point are aware that other people have uniqueperspectives, but they might not yet be able to guess exactly how or what that other person is experiencing.

Tips for Activities in the Concrete Operational Stage

Cognitive Developmental Milestones

Keep in Mind

This stage of cognitive development also serves as an important transition between the preoperational and formal operational stages.The growing ability to mentally manipulate information and think about the thoughts of others will play a critical role in theformal operational stageof development when logic and abstract thought become critical.
