安全对于生命至关重要。为了生存，人类和其他动物已经发展出一套心理和生理适应，称为生命史（LH）权衡策略，以应对各种安全限制。进化选择的 LH 策略反过来调节发育和行为，以在普遍的安全条件下优化生存。本研究基于来自 9 个国家的 1,245 名青少年及其父母的 6 年纵向样本，检验了有关安全性的 LH 假设。结果显示，环境恶劣性和不可预测性（缺乏安全性）与 2 年后测量的缓慢 LH 行为特征呈负相关，在不同国家之间不变，并且在另外 2 年后测量，缓慢 LH 行为特征分别与外化行为和学业成绩呈负相关和正相关。这些结果支持了人类发展通过 LH 对社会和学习行为的调节来响应环境安全线索的进化概念。
Safety is essential for life. To survive, humans and other animals have developed sets of psychological and physiological adaptations known as life history (LH) tradeoff strategies in response to various safety constraints. Evolutionarily selected LH strategies in turn regulate development and behavior to optimize survival under prevailing safety conditions. The present study tested LH hypotheses concerning safety based on a 6-year longitudinal sample of 1,245 adolescents and their parents from 9 countries. The results revealed that, invariant across countries, environmental harshness, and unpredictability (lack of safety) was negatively associated with slow LH behavioral profile, measured 2 years later, and slow LH behavioral profile was negatively and positively associated with externalizing behavior and academic performance, respectively, as measured an additional 2 years later. These results support the evolutionary conception that human development responds to environmental safety cues through LH regulation of social and learning behaviors.
