青春期的特点是冒险行为急剧增加。这种冒险行为的严重后果提高了识别保护因素的重要性。尽管家庭关系在青春期发生动态变化，但仍然是影响青少年的一个重要来源。我们使用纵向功能磁共振成像方法，在 1.5 年的时间内对 23 名青少年进行了两次扫描，以研究亲子关系的变化如何通过青少年对奖励的神经反应的变化来影响青少年冒险行为的变化。结果表明，尽管亲子关系与青少年冒险行为并不相关，但积极的亲子关系的增加会导致青少年冒险行为的下降。这一过程是通过冒险期间腹侧纹状体对奖励的激活纵向减少来介导的。研究结果强调了积极的亲子关系的改善可以缓冲青少年冒险行为纵向增加的神经通路。
Adolescence is marked by a steep increase in risk-taking behavior. The serious consequences of such heightened risk taking raise the importance of identifying protective factors. Despite its dynamic change during adolescence, family relationships remain a key source of influence for teenagers. Using a longitudinal fMRI approach, we scanned 23 adolescents twice across a 1.5-year period to examine how changes in parent–child relationships contribute to changes in adolescent risk taking over time via changes in adolescents’ neural reactivity to rewards. Results indicate that although parent–child relationships are not associated with adolescent risk taking concurrently, increases in positive parent–child relationships contribute to declines in adolescent risk taking. This process is mediated by longitudinal decreases in ventral striatum activation to rewards during risk taking. Findings highlight the neural pathways through which improvements in positive parent–child relationships serve to buffer longitudinal increases in adolescent risk taking.
