1 adult male and 4 adult female squirrel monkeys were observed together as a group, isolated from all other monkeys. 3 of the 4 females were deafened for a previous experiment. Deafening, however, had no apparent, permanent effect on social behavior. Social dominance hierarchy was evaluated in a variety of situations. The results were compared with those of a similar set of observations on the females prior to the introduction of the male. Before the male was introduced, the dyadic interactions involving food stealing, body grasping, and sexual behaviors were indicative of a female linear rank order. After the male was introduced, the rank order among the females generally remained intact, with the male becoming the highest ranking member in the group. The noteworthy exception to the stability involved the highest ranking female, whose position in the hierarchy was threatened. Heterosexual interactions predominated. Homosexual behavior was also observed, although appreciably reduced in frequency as compared to the all-female group situation. A similar rank order hierarchy was observed in a second group of squirrel monkeys comprised of 1 adult male and 4 adult females. None of these monkeys was deaf.
一只成年雄性松鼠猴和四只成年雌性松鼠猴作为一组被观察，与所有其他猴子隔离开来。四只雌性松鼠猴中有三只因之前的实验而致聋。然而，致聋对社交行为没有明显的永久性影响。在各种情况下评估了社会优势等级制度。将结果与在引入雄性之前对雌性进行的一组类似观察结果进行了比较。在引入雄性之前，涉及偷食、抓身体和性行为的二元互动表明了雌性的线性等级顺序。引入雄性后，雌性之间的等级顺序总体上保持不变，雄性成为群体中等级最高的成员。稳定性方面值得注意的例外涉及等级最高的雌性，其在等级制度中的地位受到了威胁。异性互动占主导。也观察到了同性行为，尽管与全雌性群体情况相比频率明显降低。在由一只成年雄性和四只成年雌性组成的第二组松鼠猴中也观察到了类似的等级制度。这些猴子都没有失聪。
