In one study, a team at the University of Oregon in Eugene got adolescents to play it in a scanner after hearing that two other teenagers were watching. But lab studies in the past decade have revealed layers of nuance in how young people assess risks. The data from neuroimaging studies are usually averaged out across participants, so drawing conclusions about any one brain is itself risky. Steinberg testified in five court cases last year concerning criminal sentences for adolescents. Understanding how the teenage brain evaluates risk could even reveal predictors of mental-health conditions such as schizophrenia and depression, which often emerge in adolescence. Peers can have positive effects, too. Images with social significance—positive pictures such as teenagers laughing or playing games on a beach, and negative ones including a group ganging up on someone—also appeared on screen.
Images with social significance—positive pictures such as teenagers laughing or playing games on a beach, and negative ones including a group ganging up on someone—also appeared on screen. In some situations, teenagers can be more risk-averse than their older peers. Areas linked with impulsivity and heightened sensitivity to reward, especially in the social realm, get an early boost in activity, whereas those governing cognitive processes such as working memory develop smoothly throughout adolescence. The other problem is that the average teenager in a study is only moderately likely to take risks. Most neuroscientists now acknowledge that neural systems developing at different rates do not mean that the brain is unbalanced. The two say that they seek out places such as construction sites and disused buildings—not to get into trouble, but to explore. Other policies aim to take away the opportunity for dangerous behaviour. In a study, teenagers were asked to donate or keep money in an online game, supposedly watched by ten peers. When they returned to the driving game after experiencing social exclusion, adolescents who said they were sensitive to peer influence took significantly more risks. But among the expelled or suspended students, it was the aversive pictures that impaired performance. In another study, Telzer and her colleagues found that teenagers who were more socially excluded or victimized took more risks. Although the opposite is also true. These types of behaviour seem to have different effects on the brain. Activity in the ventral striatum, particularly rising numbers of dopamine receptors, has been linked to the greater sensitivity that teenagers feel to rewards for positive as well as perilous behaviours. As the first lights change to amber, some teenagers choose to carry on; others wait for green. This is likely to work better than approaches based on informing students about risks, he says. There are also bragging rights to be earned. Then the researchers got the participants to play another video game, in which they were excluded from throwing and catching a ball with the same peers. In one study, a team at the University of Oregon in Eugene got adolescents to play it in a scanner after hearing that two other teenagers were watching. Steinberg has advocated limiting exposure to risk in the first place, for example by raising the minimum age for buying tobacco to 21 or prohibiting alcohol sales within metres of schools. After hearing his evidence on how decision-making in teens is influenced by emotion, a Kentucky court last year decided to raise to 21 the age at which individuals could be given the death penalty. Her team asked them to lie in a scanner and push a button when they saw letters on a screen, but not if the screen displayed an X. The academy recommends a start time of 8: And they navigate a broader range of risks than has typically been considered in the lab, including social risks and positive risks—such as trying out for a sports team. The work is part of a drive to understand who is most vulnerable. For many teenagers, says Dahl, there is risk in relatively benign experiences, such as standing up for a friend or asking someone on a date.
