在努力确定合适的刺激对象，可以被放置到标准的实验室笼子里，以提供一定程度的环境丰富的大鼠，大鼠的偏好，花时间附近的15个不同的对象进行了测量，在自由选择的范例。老鼠没有表现出对管道和隔板等物体的偏好，我们认为这些物体可能会满足他们的贴墙倾向。他们也没有表现出对我们认为可能感兴趣的物体的偏好。老鼠确实表现出了可靠的偏好，愿意花时间与一些但不是所有的咀嚼物在一起。一块预先钻好孔的木头是最有吸引力的，我们谨慎地建议研究人员考虑给实验室老鼠提供这样一个物体，让它们有机会练习一种基本的、物种典型的行为--咀嚼。
In an effort to identify suitable stimulus objects which could be placed into standard laboratory cages in order to provide rats with a degree of environmental enrichment, the preference of rats to spend time near 15 diverse objects was measured in a free-choice paradigm. Rats showed no preference for objects such as pipes and partitions which we had reasoned might satisfy a wall-hugging tendency. They also showed no preference for objects which we had reasoned to be potentially interesting as manipulanda. The rats did show reliable preferences for spending time with some, but not all, chewable objects. A block of wood predrilled with holes was the most attractive, and we cautiously recommend that researchers consider providing laboratory rats with such an object to allow them the opportunity to exercise a fundamental, species-typical behaviour-chewing.
