社会等级的功能是促进对社会压力情况和条件的应对反应。社会地位的演变似乎与压力的演变有着密不可分的联系。压力、攻击、奖励和决策神经回路重叠并相互作用，产生与地位相关的关系，这在男性和女性人群中都很常见。源于社会地位和等级关系的行为后果是由攻击性互动塑造的，这本身就是一种压力。这似乎很可能是在促应激和抗应激神经回路中调节元素的平衡导致快速而短暂的应激反应，这有利于社会支配。这些系统进一步与奖励和攻击回路协调，在获得食物、配偶、栖息地点、领土空间、庇护所和其他资源的机会出现时产生快速的适应性反应。资源的快速获取和侵略性的姿态产生了优势个体，这些个体暂时具有明显的健康优势。由于这些原因，社会地位的变化也会迅速发生。社会从属导致更慢和更慢性的神经和内分泌反应，一套独特的防御行为，以及增加焦虑和抑郁行为和情感的倾向。这两种行为表型只是一个谱系的两端，然而，它们可能会让我们深入了解无数与压力相关的疾病背后令人不安的机制，它们似乎与进化有关。
Social rank functions to facilitate coping responses to socially stressful situations and conditions. The evolution of social status appears to be inseparably connected to the evolution of stress. Stress, aggression, reward, and decision-making neurocircuitries overlap and interact to produce status-linked relationships, which are common among both male and female populations. Behavioral consequences stemming from social status and rank relationships are molded by aggressive interactions, which are inherently stressful. It seems likely that the balance of regulatory elements in pro- and anti-stress neurocircuitries results in rapid but brief stress responses that are advantageous to social dominance. These systems further produce, in coordination with reward and aggression circuitries, rapid adaptive responding during opportunities that arise to acquire food, mates, perch sites, territorial space, shelter and other resources. Rapid acquisition of resources and aggressive postures produces dominant individuals, who temporarily have distinct fitness advantages. For these reasons also, change in social status can occur rapidly. Social subordination results in slower and more chronic neural and endocrine reactions, a suite of unique defensive behaviors, and an increased propensity for anxious and depressive behavior and affect. These two behavioral phenotypes are but distinct ends of a spectrum, however, they may give us insights into the troubling mechanisms underlying the myriad of stress-related disorders to which they appear to be evolutionarily linked.
