Piaget's cognitive development stage beginning around age 6-7, where a child can think logically about concrete objects and reversibility, but struggles with abstract concepts?

• A. Concrete stage of cognitive development
• B. Inductive logic
• C. Preformationist Theory
• D. Mechanistic Theory

Answer: (A)

This describes Piaget's concrete operational stage, which begins around age 7. In this stage children can think logically about concrete objects and events and understand reversibility—the idea that actions can be undone and the outcome can be returned to the original state. They also develop skills like conservation, classification, and seriation, and they reason well about real, tangible situations. But when ideas become abstract or hypothetical, they still struggle because their thinking relies on concrete experiences. So this stage fits the description of thinking logically about concrete things while having trouble with abstract concepts.

The other options aren’t about Piaget’s stages. Inductive logic is a general reasoning pattern, not a developmental stage. Preformationist theory is a historical biology idea about reproduction, not cognitive development. Mechanistic theory is a way of explaining behavior or systems as machines, not a stage of child thinking.
