Observations of stumptail monkeys revealed frequent prolonged, intensive genital stimulation between individuals of the same sex, both males and females, adults and infants. These homosexual interactions occurred in positive emotional contexts, were accompanied by positive emotional facial expressions, and often were evidently elictied by the observation of heterosexual behavior. Infants' first copulations were performed with adults of the same or opposite sex who actively aided them. This suggests that homosexual and heterosexual encounters function as training for adult sexual roles, and that homosexual behavior is a basic primate pattern not exclusive to man.
对短尾猴的观察发现，同性个体之间，包括雄性与雄性、雌性与雌性、成年个体与幼崽之间，频繁出现长时间的强烈生殖器刺激行为。这些同性互动发生在积极的情绪情境中，伴随着积极的情绪面部表情，并且常常明显是由观察异性性行为引发的。幼崽的首次交配是与积极协助它们的同性或异性成年个体进行的。这表明同性和异性接触起到了对成年性行为角色的训练作用，并且同性行为是一种基本的灵长类模式，并非人类所独有。
