The most common form of stress encountered by people stems from one's social environment and is perceived as more intense than other types of stressors. One feature that may be related to differential resilience or vulnerability to stress is the type of strategy used to cope with the stressor, either active or passive coping. This review focuses on models of social stress in which individual differences in coping strategies produce resilience or vulnerability to the effects of stress. Neurobiological mechanisms underlying these individual differences are discussed. Overall, the literature suggests that there are multiple neural mechanisms that underlie individual differences in stress-induced resilience and vulnerability. How these mechanisms interact with one another to produce a resilient or vulnerable phenotype is not understood and such mechanisms have been poorly studied in females and in early developmental periods. Finally, we propose that resilience may be stress context specific and resilience phenotypes may need to be fine-tuned to suit a shifting environment.
人们遇到的最常见的压力形式源于其社会环境,且被认为比其他类型的压力源更为强烈。一个可能与应对压力的不同恢复力或易感性相关的特征是用于应对压力源的策略类型,即主动应对或被动应对。本综述聚焦于社会压力模型,其中应对策略的个体差异会产生对压力影响的恢复力或易感性。讨论了这些个体差异背后的神经生物学机制。总体而言,文献表明存在多种神经机制构成了压力诱导的恢复力和易感性的个体差异基础。这些机制如何相互作用以产生恢复力或易感性表型尚不清楚,并且在女性和早期发育阶段对这些机制的研究很少。最后,我们提出恢复力可能是特定于压力情境的,恢复力表型可能需要进行微调以适应不断变化的环境。
