冲动性的个体差异是青少年时期所观察到的大量冒险行为的基础，而这种行为中一些最危险的形式与发育早期明显的冲动性特征有关。然而，早期干预似乎能够通过增加对行为的控制和对有价值目标的坚持来降低这些特征的严重性和影响，例如教育成就。冲动的一种形式，感觉寻求，在青春期急剧上升，并增加了健康发展的风险。然而，对青春期大脑发育的局限性限制了控制冲动的能力这一假设的证据进行了回顾，表明任何此类限制充其量都是微妙的。相反，有人认为，缺乏新的成人行为的经验，对青少年造成的风险要比大脑成熟的结构性缺陷大得多。持续的转化研究将有助于确定在青年向成年过渡时保护他们的战略。
Individual differences in impulsivity underlie a good deal of the risk taking that is observed during adolescence, and some of the most hazardous forms of this behavior are linked to impulsivity traits that are evident early in development. However, early interventions appear able to reduce the severity and impact of these traits by increasing control over behavior and persistence toward valued goals, such as educational achievement. One form of impulsivity, sensation seeking, rises dramatically during adolescence and increases risks to healthy development. However, a review of the evidence for the hypothesis that limitations in brain development during adolescence restrict the ability to control impulsivity suggests that any such limitations are subtle at best. Instead, it is argued that lack of experience with novel adult behavior poses a much greater risk to adolescents than structural deficits in brain maturation. Continued translational research will help to identify strategies that protect youth as they transition to adulthood.
