Answer to Question 1
The key to understanding adolescent cognitive development is to understand Piaget's concept of formal operations. The adolescent entering this stage enjoys new intellectual abilities, including being able to engage in abstract and hypothetical thinking. This sometimes leads to a pattern of thinking called what if. In this pattern of thinking, adolescents begin to imagine a world better than the one in which they are living. In addition, the adolescent can understand metaphors in which words or phrases that typically signify one thing can be applied to another.
