Which stage of Piaget's theory occurs from adolescence through adulthood?

• A. Formal Operational
• B. Sensorimotor
• C. Preoperational
• D. Concrete Operational

Answer: (A)

Thinking about abstract ideas and what could be possible develops during adolescence and continues into adulthood. This stage, Formal Operational, brings abilities like hypothetical-deductive reasoning, planning ahead, and evaluating ideas systematically without needing concrete examples. You can think about problems with multiple variables, imagine different scenarios, and test outcomes in your mind. Those capacities mark this stage, setting it apart from the earlier stages that focus on concrete actions and real objects. So, the stage that occurs from adolescence through adulthood is the Formal Operational stage. While many people reach this level, how fully it’s used can vary by individual and context.
