According to Piaget's theory, what cognitive changes occur in children aged 6 to 12 years?

In Piaget's theory, children aged 6 to 12 years are in the concrete operational stage of cognitive development. During this stage, they experience significant growth in logical thinking. They begin to think logically about concrete events and can understand the concept of conservation, which means they recognize that quantity does not change even when its shape does. Children in this age group can classify objects, perform operations mentally, and understand the concepts of time and number, which are all indicators of logical thinking development.

While other areas, such as moral reasoning and self-identity formation, continue to develop during this period, these are not the core cognitive changes emphasized by Piaget for this specific age group. The focus at this stage is primarily on the ability to reason and logically solve problems within concrete parameters. Thus, the growth in logical thinking is the most representative cognitive change for children between 6 and 12 years according to Piaget's framework.
