本研究以进化发展理论为指导，探讨了早期家庭环境和心理生物反应对青春期的影响。正如该理论所预测的那样，在对环境表现出高度生物敏感性的儿童中（即，较高的压力反应性），较高质量的亲子关系预测较慢的初始青春期的节奏和较晚的青春期的时间，而较低质量的亲子关系预测相反的模式。在对环境不太敏感的儿童中没有出现这种影响。而交感神经系统的反应缓和的影响，亲子关系对乳房/生殖器和阴毛的发展，肾上腺皮质激活只缓和阴毛的发展。目前的结果建立在以前的研究记录什么样的家庭环境预测青春期时间的变化，通过展示这些环境的重要性。此外，作者提出了一种新的方法学途径，评估青春期节奏使用分段生长曲线分析。
Guided by evolutionary-developmental theories of biological sensitivity to context and reproductive development, the current research examined the interactive effects of early family environments and psychobiologic reactivity to stress on the subsequent timing and tempo of puberty. As predicted by the theory, among children displaying heightened biological sensitivity to context (i.e., higher stress reactivity), higher quality parent-child relationships forecast slower initial pubertal tempo and later pubertal timing while lower quality parent-child relationships forecast the opposite pattern. No such effects emerged among less context-sensitive children. Whereas sympathetic nervous system reactivity moderated the effects of parent-child relationships on both breast/genital and pubic hair development, adrenocortical activation only moderated the effect on pubic hair development. The current results build on previous research documenting what family contexts predict variation in pubertal timing by demonstrating for whom those contexts matter. In addition, the authors advance a new methodological approach for assessing pubertal tempo using piecewise growth curve analysis.
