Piaget's formal operational stage refers to the fourth and final stage of cognitive development, which occurs during adolescence and beyond. It is characterized by the ability to think abstractly, reason hypothetically, and engage in logical deductive reasoning.
Piaget's Formal Operational Stage is the final stage in his cognitive development theory, highlighting abstract, systematic, and logical thinking capabilities that emerge in adolescence.
