青春期是大脑发生重要变化的时期，为成人学习过程铺平了道路。然而，青春期的学习在多大程度上最能被描述为从童年到成年的过渡线性进展，或者代表一个不同于早期和后期发展阶段的时期，目前尚不清楚。在此，我们以啮齿类动物为研究对象，研究了有关联想恐惧条件反射和复杂选择行为的行为学文献。恐惧制约的许多方面在青春期是完整的，与成人的模式没有什么不同。然而，充分的证据表明，青少年的学习不能简单地描述为成年的不成熟前兆。在评估选择行为的不同范式中，文献表明，与成年动物相比，青春期动物通常表现出更多的冲动反应模式。基本条件反射过程的发展在多大程度上为成年后的决策提供了支撑，这是一个重要的理论研究领域，但也广泛应用于许多心理状况。
Adolescence is a time of critical brain changes that pave the way for adult learning processes. However, the extent to which learning in adolescence is best characterized as a transitional linear progression from childhood to adulthood, or represents a period that differs from earlier and later developmental stages, remains unclear. Here we examine behavioral literature on associative fear conditioning and complex choice behavior with rodent models. Many aspects of fear conditioning are intact by adolescence and do not differ from adult patterns. Sufficient evidence, however, suggests that adolescent learning cannot be characterized simply as an immature precursor to adulthood. Across different paradigms assessing choice behavior, literature suggests that adolescent animals typically display more impulsive patterns of responding compared to adults. The extent to which the development of basic conditioning processes serves as a scaffold for later adult decision making is an additional research area that is important for theory, but also has widespread applications for numerous psychological conditions.
