A detailed quantitative analysis of sexual behavior in a social group of captive stumptail macaques was conducted. The distribution of copulations both over days and among animals, and the relationships between copulation and various sociosexual patterns were investigated. Copulations occurred erratically over days and were preferentially directed to a small minority of females. Most patterns of sociosexual behavior were at their highest rates during actual copulatory episodes, others occurred independent of ejaculation. It is suggested that the relationships between variables such as social rank, age and parity and sociosexual patterns are quite flexible and probably vary with the species, testing conditions and demographic make-up of the group.
对一群圈养断尾猕猴的性行为进行了详细的定量分析。研究了交配在不同天数以及不同个体间的分布情况，以及交配与各种社会性行为模式之间的关系。交配在不同天数中无规律地发生，且优先指向少数雌性。大多数社会性行为模式在实际交配期间发生率最高，其他模式则与射精无关。研究表明，诸如社会等级、年龄和生育状况等变量与社会性行为模式之间的关系相当灵活，可能因物种、测试条件和群体的人口构成而异。
