青春期是身体、认知、情感和社会发生巨大变化的时期，也是许多社会情感问题发展的时期。这些特征提出了关于伴随神经变化的令人信服的问题，这些变化是这一发育时期独有的。在这里，我们认为，研究青少年特有的面孔加工变化及其潜在的神经回路为解决这些问题提供了一个理想的模型。我们也使用这个模型来提出新的假设。具体地说，青春期荷尔蒙可能会增加掌握新的以同伴为导向的发展任务的动机，这反过来又会刺激面孔加工中新的社会/情感成分的出现。我们还预测，青春期激素对支持面孔处理的神经回路的重组具有根本性的影响，并特别提出，随着青春期面孔处理的这些新组成部分的出现，面孔处理网络区域之间的功能连接或时间同步将发生变化。最后，我们展示了这种方法将如何帮助揭示为什么青春期可能是大脑发育中的脆弱时期，并建议它如何导致预防和干预战略，以促进更广泛的社会信息处理网络中区域之间的更适应的功能互动。
Adolescence is a time of dramatic physical, cognitive, emotional, and social changes as well as a time for the development of many social-emotional problems. These characteristics raise compelling questions about accompanying neural changes that are unique to this period of development. Here, we propose that studying adolescent-specific changes in face processing and its underlying neural circuitry provides an ideal model for addressing these questions. We also use this model to formulate new hypotheses. Specifically, pubertal hormones are likely to increase motivation to master new peer-oriented developmental tasks, which will in turn, instigate the emergence of new social/affective components of face processing. We also predict that pubertal hormones have a fundamental impact on the reorganization of neural circuitry supporting face processing and propose, in particular, that, the functional connectivity, or temporal synchrony, between regions of the face-processing network will change with the emergence of these new components of face processing in adolescence. Finally, we show how this approach will help reveal why adolescence may be a period of vulnerability in brain development and suggest how it could lead to prevention and intervention strategies that facilitate more adaptive functional interactions between regions within the broader social information processing network.
