In Piaget's theory, which period is characterized by formal operational thinking, including abstract reasoning?

• A. Period I
• B. Period II
• C. Period III
• D. Period IV

Answer: (D)

The main idea being tested is the emergence of abstract, hypothetical-deductive reasoning that Characterizes formal operational thinking. In Piaget's stages, this final period marks a shift from thinking about things that are concrete and directly observable to thinking about possibilities, abstract concepts, and systematic ways to test ideas. Adolescents learn to reason about variables, consider multiple hypotheses, and plan approaches in a purely mental way, without needing real objects to manipulate. This contrasts with earlier stages, where thinking centers on concrete situations and visible operations with tangible items. That’s why this period—often beginning in early adolescence and lasting into adulthood—is the one associated with formal operational thinking and abstract reasoning.
