预测一个人未来的社会地位而不进行积极的社会互动似乎是矛盾的，因为社会地位的形成取决于竞争性的互动。在蜥蜴Anolis carolinensis中，预测社会等级是可能的，使用眼斑形成的潜伏期（在紧张的竞争性相互作用期间，眶后皮肤从绿色变黑的交感神经变暗），因为它们在成为主导的雄性蜥蜴中形成得更快。变暗的眼斑也会抑制攻击性行为。由于眼斑形成的时间似乎是压力反应和未来社会地位的重要组成部分，我们假设，对非攻击性行为的主动倾向，如喂养和求爱，将与攻击性。我们评估了等级和时间动态的眼斑形成，laverness侵略性的显示，喂养和生殖行为之间的关系。雄性蜥蜴变得占主导地位的反应更快，所有类型的刺激测试（侵略，喂养和求爱）。神经内分泌应激反应的时间动态似乎会影响行为反应的动机。从压力中恢复得更快的动物也更容易进食、求偶和打斗。总之，这项工作表明，攻击，繁殖和进食行为，以及眼斑信号，是可靠的预测个体男性的未来社会地位。carolinensis。
Predicting the future social standing of an individual without aggressive social interaction may seem contradictory, as formation of social rank depends on agonistic interactions. In the lizard Anolis carolinensis, predicting social rank is possible using latency to eyespot formation (sympathetic darkening of postorbital skin from green to black during stressful agonistic interactions), because they form more rapidly in male lizards that become dominant. Darkened eyespots also inhibit aggressive behavior. As the timing of eyespot formation appears to be an important component of stress responsiveness and future social status, we hypothesized that a proactive disposition toward non-aggressive behavior, such as feeding and courtship, would be associated with aggressiveness. We assessed the relationship between rank and the temporal dynamics of eyespot formation, latencies to aggressive display, feeding, and reproductive behavior. Male lizards that became dominant were faster to respond to all types of stimuli tested (aggression, feeding, and courtship). The temporal dynamics of the neuroendocrine stress response appear to influence the motivation for behavioral response. Animals that recover from stress more quickly also eat, court, and fight more readily. In summary, this work suggests that latencies to aggressive, reproductive, and feeding behavior, as well as eyespot signals, are reliable predictors of future social status of individual male A. carolinensis.
