The best way to guide your teenager through the high-risk years.

Alan Kazdin & Carlo Rotella:

Our last article summarized the current state of research on teens and risk. That research demonstrates that teenagers do not suffer from some special inability to reason. Larry Steinberg and other researchers explain the steep rise in risk-taking behavior that comes with puberty by elaborating the interplay between two brain systems. The social-emotional system, which develops robustly in early adolescence, seeks out rewarding experiences, especially the sensation afforded by novel and risky behavior, and is also activated by the presence of peers. The cognitive-control system, which undergoes its great burst of development in later adolescence, evaluates and governs the impulses of the social-emotional system.

During the years of greatest risk-taking, which peak somewhere around the age of 16 and during which the presence of peers greatly increases risk-taking, the adolescent brain is like a car with a powerful accelerator (the sensation- and peer-seeking social-emotional system) and weak brakes (the risk-containing cognitive-control system). That being the case, it's clear why some common approaches to reducing risk-taking by teenagers--explaining why drunk driving is dangerous, asking them to pledge to abstain from premarital sex--don't work very well.
