Aspects of a monogamous relationship can be inferred by observing reactions of mated individuals to unfamiliar conspecifics. The present study examined the behaviours shown by male and female titi monkeys (Callicebus moloch) toward an opposite-sex stranger, and the effect of their pairmate's absence or presence on these encounters. Behaviours within unfamiliar heterosexual pairs showed superficial similarities to behaviours of mated pairs. Although there were few affiliative behaviours between unfamiliar individuals, animals were often in spatial proximity and even performed sexual behaviour. The visual presence of a pairmate clearly affected encounters between unfamiliar heterosexual pairs in several respects. The presence of a male pairmate had a much stronger influence on all behavioural measures compared to the presence of a female pairmate. Possible functional aspects of these results are discussed.
通过观察配对个体对陌生同种个体的反应，可以推断出一夫一妻制关系的一些方面。本研究考察了雌雄伶猴（Callicebus moloch）对异性陌生人表现出的行为，以及它们的配偶在场或不在场对这些相遇情况的影响。陌生异性配对中的行为与配对配偶的行为表现出表面相似性。尽管陌生个体之间的亲和行为很少，但动物们经常在空间上接近，甚至进行性行为。配偶的视觉存在显然在几个方面影响了陌生异性配对之间的相遇。与雌性配偶在场相比，雄性配偶在场对所有行为指标的影响要大得多。本文讨论了这些结果可能的功能方面。
