Quizplus · Accepted Answer

This question requires knowledge of Piaget's theory of cognitive development. According to Piaget, children at around 8 years old begin to develop the ability to categorize and classify objects, including themselves. They start to understand that they have specific abilities in certain areas (like games) and not in others (like singing). Therefore, a child who judges himself to be good at games but a poor singer is likely around 8 years old.
