社会行为通常被描述为一个统一的概念，但高度社会化（群体生活）的物种表现出不同的社会结构，并可能做出不同的社会决策。草原田鼠（Microtus ochrogaster）是一种社会性的一夫一妻制啮齿动物，通常居住在大家庭群体中，并在扩展选择测试中对熟悉的社会伙伴（同性和异性）表现出强烈的偏好，尽管短期偏好尚不清楚。小鼠（Mus musculus）是群居和殖民的，但在简单的社会偏好实验室测试中，它们通常更喜欢社会新奇。这种对陌生同伴和熟悉同伴的偏好可能代表了老鼠和草原田鼠之间在社会决策方面的物种特异性差异。然而，用于测量每个物种偏好的测试在接触的持续时间和程度上存在显着差异，因此无法直接比较行为。我们评估了在使用匹配协议进行评估时，小鼠和草原田鼠对新奇性或熟悉性的社会偏好是否存在差异：通常用于小鼠的社交性/社会偏好测试（SPT）（短，无直接接触）和用于田鼠的伴侣偏好测试（PPT）（长，直接接触）。一部分田鼠还接受了使用屏障（长时间，无直接接触）的PPT。在短SPT中，行为在物种之间没有差异。在较长的测试中，草原田鼠出现了明显的伴侣偏好，但老鼠没有表现出社会偏好，也很少挤在一起。两项试验均无明显的性别差异。在田鼠的蜷缩时间的合作伙伴的偏好，需要直接的身体接触，但合作伙伴室的偏好是显而易见的，或没有接触。草原田鼠和老鼠都是社会性的，但它们在社会行为的特异性和程度上表现出重要的差异。虽然老鼠经常被用来研究社会行为和其他行为，但田鼠是更适合研究选择性社会关系的物种。考虑到这些差异将是重要的研究检查支持不同种类的同伴社会行为的神经机制。
Social behavior is often described as a unified concept, but highly social (group-living) species exhibit distinct social structures and may make different social decisions. Prairie voles (Microtus ochrogaster) are socially monogamous rodents that often reside in extended family groups, and exhibit robust preferences for familiar social partners (same- and opposite-sex) during extended choice tests, although short-term preferences are not known. Mice (Mus musculus) are gregarious and colonial, but in brief laboratory tests of social preference they typically prefer social novelty. This preference for novel vs. familiar peers may represent a species-specific difference in social decision-making between mice and prairie voles. However, the tests used to measure preferences in each species differ markedly in duration and degree of contact, such that the behaviors cannot be directly compared. We assessed whether social preferences for novelty or familiarity differed between mice and prairie voles of both sexes when assessed with matching protocols: the sociability/social preference test (SPT) typically used in mice (short, no direct contact), and the partner preference test (PPT) used in voles (long, direct contact). A subset of voles also underwent a PPT using barriers (long, no direct contact). In the short SPT, behavior did not differ between species. In the longer test, pronounced partner preferences emerged in prairie voles, but mice exhibited no social preferences and rarely huddled. No sex differences were evident in either test. Direct physical contact was required for partner preferences in huddling time in voles, but preference for the partner chamber was evident with or without contact. Both prairie voles and mice are social, but they exhibit important differences in the specificity and extent of their social behavior. While mice are often used to study social approach and other behaviors, voles are a more suitable species for the study of selective social relationships. Consideration of these differences will be important for studies examining the neural mechanisms supporting different kinds of peer social behavior.
