3. Think about thinking (metacognition)
4. Think in multiple dimensions
5. See knowledge as relative (relativism)
What happens when teens start thinking about possibilities?
There is a development of deductive reasoning - "if-then" thinking. This is a major intellectual accomplishment. Example: ways in which their lives may be affected by different career choices. They can move easily between specific and abstract to generate alternative possibilities.

Which part of the brain is pruned in adolescence?
The prefrontal cortex the region responsible for sophisticated thinking abilities such as planning, thinking weighing risks and rewards and controlling impulses
What are two major changes that take place in the brain in adolescence?

What is convergent thinking?
How two different things are alike

2. Ventromedial - gut reactions, instincts
3. Orbitofrontal - risks vs. rewards
Changes in the brain is affected by two neurotransmitters.
1. Dopamine - role in experience of reward
