有人假设，追求奖励和冲动是沿着不同的时间表发展的，具有不同的神经基础，它们时间表的不同有助于解释青春期冒险行为的加剧。为了检验这些命题，研究人员对935名年龄在10岁到30岁之间的不同社会经济和种族个体进行了年龄差异的研究，这些样本包括自我报告和每个结构的行为测量。与预测一致的是，寻求奖励的年龄差异遵循曲线模式，在青春期前和青春期中期增加，之后下降。相比之下，冲动的年龄差异遵循线性模式，冲动从10岁开始稳步下降。青春期中期对冒险行为的易感性可能是由于相对较高的寻求回报的倾向和仍在成熟的自我控制能力的共同作用。(C)2010 Wiley期刊，Inc.开发心理学52：216-224,2010。
It has been hypothesized that reward-seeking and impulsivity develop along different timetables and have different neural underpinnings, and that the difference in their timetables helps account for heightened risk-taking during adolescence. In order to test these propositions, age differences in reward-seeking and impulsivity were examined in a socioeconomically and ethnically diverse sample of 935 individuals between the ages of 10 and 30, using self-report and behavioral measures of each construct. Consistent with predictions, age differences in reward-seeking follow a curvilinear pattern, increasing between preadolescence and mid-adolescence, and declining thereafter In contrast, age differences in impulsivity follow a linear pattern, with impulsivity declining steadily from age 10 on. Heightened vulnerability to risk-taking in middle adolescence may be due to the combination of relatively higher inclinations to seek rewards and still maturing capacities for self-control.
