An attempt was made to pair ten unrelated, adult male rhesus monkeys that had been kept in single cages for several years. Potential companions were first given the opportunity to establish clear-cut rank relationships (unidirectional fear-grinning and/or withdrawing) during a 5-day period of noncontact familiarization. Only then were they paired in a different double cage. Rank relationships were confirmed within the first 6 minutes after pairing without the occurrence of any biting and fighting. A total of four physical aggressions (slapping) were observed in all five dyads during 5 hours of observations on the first 5 days after pairing. It was concluded that the establishment of clear-cut rank relationships prior to pairing was instrumental in this extremely low incidence of aggression.
研究人员尝试将十只彼此不相关的成年雄性恒河猴配对，这些猴子已在单笼中饲养数年。在为期5天的非接触式熟悉期内，首先让潜在的同伴们有机会建立明确的等级关系（单向的恐惧露齿和/或回避）。之后才将它们配对放入不同的双笼中。配对后的前6分钟内就确认了等级关系，且没有发生任何撕咬和打斗。在配对后的前5天进行的5小时观察中，在所有五对组合中总共观察到四次身体攻击行为（拍打）。研究得出结论，配对前建立明确的等级关系有助于使攻击行为的发生率极低。
