了解奖励系统中的不成熟如何影响决策,可以让我们了解青少年对冒险的脆弱性,这是这个年龄组死亡率和药物滥用的主要原因。在这篇文章中,我们回顾了有关奖赏和认知控制的神经发育的文献,并提出了一个青少年奖赏加工的模型。虽然成熟的奖励系统的功能神经解剖学已经被很好地描绘出来,但青少年的奖励处理才刚刚开始被理解。结果表明,青少年相对于成年人表现出减少预期的处理和评估的风险,但增加完善的反应。这种差异可能会导致次优的回报价和价值和偏见青少年的决策表示。奖励处理的这些功能差异与青少年大脑中正在进行的结构和药理学成熟平行发生。除了在激励处理方面的限制,基本的认知控制能力,包括工作记忆和抑制控制,在青春期继续成熟。因此,青少年可能是有限的,相对于成年人,在他们的能力,以抑制冲动的行为,并可靠地举行“在线”比较潜在的奖励/惩罚在决策。
Understanding how immaturities in the reward system affect decision-making can inform us on adolescent vulnerabilities to risk-taking, which is a primary contributor to mortality and substance abuse in this age group. In this paper, we review the literature characterizing the neurodevelopment of reward and cognitive control and propose a model for adolescent reward processing. While the functional neuroanatomy of the mature reward system has been well-delineated, adolescent reward processing is just beginning to be understood. Results indicate that adolescents relative to adults demonstrate decreased anticipatory processing and assessment of risk, but an increased consummatory response. Such differences could result in suboptimal representations of reward valence and value and bias adolescent decision-making. These functional differences in reward processing occur in parallel with on-going structural and pharmacological maturation in the adolescent brain. In addition to limitations in incentive processing, basic cognitive control abilities, including working memory and inhibitory control, continue to mature during adolescence. Consequently, adolescents may be limited, relative to adults, in their abilities to inhibit impulsive behaviors and reliably hold ‘on-line’ comparisons of potential rewards/punishments during decision-making.
