The slender loris is a nocturnal primate of India and Sri Lanka. Diurnal primates, such as monkeys, apes and lemurs, have served as the primary subjects for testing hypotheses about the origin and adaptiveness of gregarious living in primates. Anthropologists have hypothesized that social groups are favored when primates utilize clumped food resources, such as fruit in a large canopy tree, or that social grouping is a correlate of primates' delayed life histories (i.e., slow growth and dependent childhood). Any robust hypotheses intended to explain primate sociality must be able to account for the specific cases of the less gregarious nocturnal primates. This study addresses the following general questions about lorises: 1) What are the social correlates of foraging for dispersed fruit or insect resources? 2) What are the social correlates of feeding upon spatially clumped food items? 3) What are the social correlates of delayed life history? Study methods are designed to statistically isolate and characterize the contexts in which lorises express social interactions, which in turn will test social theory developed from the diurnal primates. An additional significance of this study is that supplemental information obtained about habitat preferences and behavior will contribute to conservation of the threatened loris.

细长的懒猴是印度和斯里兰卡的夜行灵长类动物。 昼行灵长类动物，如猴子、猿和狐猴，已成为检验灵长类群居生活的起源和适应性假设的主要对象。 人类学家假设，当灵长类动物利用聚集的食物资源（例如大树冠上的果实）时，社会群体会受到青睐，或者社会群体与灵长类动物的延迟生活史（即生长缓慢和依赖童年）有关。 任何旨在解释灵长类动物社会性的强有力的假设都必须能够解释不太群居的夜间灵长类动物的具体情况。 本研究解决了以下关于懒猴的一般性问题：1）寻找分散的水果或昆虫资源的社会相关性是什么？ 2）以空间聚集的食物为食的社会相关性是什么？ 3) 生活史延迟的社会相关因素是什么？ 研究方法旨在统计上分离和描述懒猴表达社会互动的背景，这反过来将测试从昼间灵长类动物发展而来的社会理论。 这项研究的另一个重要意义是，获得的有关栖息地偏好和行为的补充信息将有助于保护受威胁的懒猴。
