What are the implications of recent research findings about the adolescent brain for social policy? This research is leading to a number of policy discussions about several issues, including the timing of the school day; regulations for adolescent driving, including the legal age of driving, whether evening driving should be allowed, whether other adolescents can be present in the car of an adolescent driver, and so on; the drinking age; and the age when a juvenile can be tried as an adult in a court of law. What opinions do you hold about these issues? How are those opinions shaped by recent brain research?
