Abstract

The developmental period of adolescence is characterized by increasing incidence of health risk behaviors (HRBs). Based on theoretical models that emphasize the moderating role of cognitive control, this study examined how neural correlates of cognitive control and risk sensitivity interact to predict HRBs among late adolescents (17-20 years). Neuroimaging data indicate that risk-related hemodynamic activity in the anterior insula during anticipation of uncertain outcomes predicts HRBs among late adolescents exhibiting greater dorsal anterior cingulate cortex (dACC) activity during a cognitive interference task but not among late adolescents requiring less dACC activity. These results present neural evidence for a significant moderating effect of cognitive control on the link between risk sensitivity and HRBs among late adolescents.

摘要

青春期是健康风险行为(HRBs)发生率增加的时期。基于强调认知控制调节作用的理论模型,本研究探讨了认知控制和风险敏感性的神经相关性如何相互作用,以预测晚期青少年(17-20 岁)的 HRBs。神经影像学数据表明,在对不确定结果进行预期时,前岛叶的与风险相关的血液动力学活动可预测在认知干扰任务中表现出更大背侧前扣带皮层(dACC)活动的晚期青少年中的 HRBs,但不能预测需要较少 dACC 活动的晚期青少年中的 HRBs。这些结果提供了神经学证据,表明认知控制对晚期青少年中风险敏感性与 HRBs 之间的关联具有显著的调节作用。
