Final answer:
Piaget's formal operational stage is when children are capable of debating social matters and abstract ideas, typically beginning from age 11 into adulthood.
Step-by-step explanation:
The cognitive stage described by Piaget in which children are able to debate social matters and other abstract ideas is known as the formal operational stage. This is the final stage of Piaget's theory of cognitive development and is typically reached from the age of 11 into adulthood. During this stage, individuals can think abstractly, engage in hypothetical thinking, demonstrate advanced problem solving, and consider alternatives and possible outcomes in various situations. It is during this stage that adolescents become capable of processing complex social and moral issues and engage in higher-level thinking about politics, religion, and justice.The cognitive stage in which children are able to debate social matters and other abstract ideas is called Formal Operational Stage in Piaget's theory of cognitive development. This stage occurs from about age 11 to adulthood. In the Formal Operational Stage, children can think abstractly, use hypothetical thinking, and engage in logical reasoning. They can problem-solve, consider alternative solutions, and test these solutions.
