Guided by principles of life history strategy development, this study tested the hypothesis that sexual precocity and violence are influenced by sensitivities to local environmental conditions. Two models of strategy development were compared: The first is based on indirect perception of ecological cues through family disruption and the second is based on both direct and indirect perception of ecological stressors. Results showed a moderate correlation between rates of violence and sexual precocity (r = 0.59). Although a model incorporating direct and indirect effects provided a better fit than one based on family mediation alone, significant improvements were made by linking some ecological factors directly to behavior independently of strategy development. The models support the contention that violence and teenage pregnancy are part of an ecologically determined pattern of strategy development and suggest that while the family unit is critical in affecting behavior, individuals' direct experiences of the environment are also important.
本研究以生活史策略发展的原则为指导，检验了以下假设：性早熟和暴力受对当地环境条件敏感性的影响。比较了两种策略发展模型：第一个模型基于通过家庭破裂间接感知生态线索，第二个模型基于直接和间接感知生态压力源。研究结果显示，暴力和性早熟的比率呈中度相关（r=0.59）。尽管纳入直接和间接效应的模型比仅基于家庭中介的模型拟合度更好，但通过将一些生态因素直接与行为联系起来，而不依赖于策略发展，模型的拟合度得到了显著提高。这些模型支持这样一种观点，即暴力和少女怀孕是生态决定的策略发展模式的一部分，并表明尽管家庭单位对行为有重要影响，但个体对环境的直接体验也很重要。
