Which Piagetian stage begins around age 11 and enables hypothetical deductive reasoning?

• A. Stage 3 Concrete Operations Period
• B. Stage 4 Formal Operations Period
• C. Hypothetical Deductive Reasoning
• D. Object Permanence

Answer: (B)

Abstract, systematic thinking marks the transition to formal operations. Around age 11, adolescents begin to think beyond concrete objects and real-life experiences, enabling them to reason about possibilities, ideals, and hypothetical scenarios. This includes hypothetical-deductive reasoning—the ability to form a general hypothesis, deduce consequences, and test ideas in a structured way by manipulating variables. Before this stage, during concrete operations, thinking is logical but tied to concrete, tangible objects and events, not abstract possibilities. Object permanence, on the other hand, is a skill from the sensorimotor period, developed in infancy.
