合作是一种认知要求很高的复杂社会行为，主要见于灵长类动物。在这里，我们研究了互惠在大鼠（褐家鼠），一种简单的合作形式，其中两个主题的工作操作性任务，立即和同时获得蔗糖奖励的联合行动。为了获得蔗糖奖励，熟悉的老鼠对被要求同时戳鼻子。经过44天的训练，我们研究了社会接触和超声波发声与大鼠的合作行为的关系，通过测试插入不透明的，金属丝网，或没有分区之间的主题。合作行为（同时戳鼻子）：（a）在初始训练期间逐渐增加;（B）随着不透明隔板（限制视觉、听觉和身体交流）而减少;（c）随着金属丝网隔板（仅限制身体接触）而增加;（d）随着50 kHz USV“快乐”呼叫的次数和社会互动的强度而增加。使用基于市售设备的简单程序研究实验室大鼠合作行为发展的可能性可能被证明有助于对社会行为的决定因素进行建模。
Cooperation is a cognitively demanding, complex social behavior, found primarily in primates. Here we investigated mutualism in rats (Rattus Norvegicus), a simple form of cooperation in which two subjects work on operant task, receiving immediate and simultaneous sucrose reward for a joint action. To receive the sucrose reward, familiar pairs of rats were required to nose poke simultaneously. Following 44 training days, we examined the relation of social contact and ultrasonic vocalizations to the rat's cooperative behavior by testing the effects of inserting opaque, wire-mesh, or no partition - between subjects. Cooperative behavior (simultaneous nose-poking): (a) increased gradually during initial training; (b) decreased with the opaque partition (restricting visual, acoustic, and physical communication); (c) increased with a wire mesh partition restricting only physical contact); and (d) increased with the number of 50 kHz USV "happy" calls and the intensity of social interaction. The possibility of studying the development of cooperative behavior in laboratory rats using a simple procedure based on commercially available equipment may prove useful in modeling determinants of social behavior.
