At what age range is the concrete operational stage typically observed in cognitive development?

• A. Ages 7 to 11
• B. Ages 3 to 5
• C. Ages 12 to 15
• D. Ages 15 to 18

Answer: (A)

Piaget's concrete operational stage is when children begin to think logically about concrete objects and events. They can perform mental operations such as conservation, reversibility, and decentration, and they can classify and seriate based on multiple attributes, all anchored in real, tangible experiences. This logical, organized thinking typically emerges around ages 7 to 11. Before this, during the preoperational stage, thinking is more egocentric and intuitive, not yet capable of flexible logical operations. After this period, in the formal operational stage, adolescents develop abstract and hypothetical reasoning. So, the age range that fits the concrete operational stage is about 7 to 11 years.
