Largely.
Preoperational stage: from ages 2 to 7 (magical thinking predominates. Acquisition of motor skills). Egocentrism begins strongly and then weakens. Children cannot conserve or use logical thinking.
- Concrete operational stage: from ages 7 to 11 (children begin to think logically but are very concrete in their thinking). Children can now conserve and think logically but only with practical aids. They are no longer egocentric.
- Formal operational stage: from age 11-16 and onwards (development of abstract reasoning). Children develop abstract thought and can easily conserve and think logically in their mind.
