Albino rats can reliably distinguish between the odors of stressed and unstressed rats. Five animals learned to interrupt an ongoing response when air from the cages of stressed rats was introduced into the test compartment, and to continue responding when air from unstressed rats was introduced. The discrimination does not seem to depend on recognition of odors of individual rats.
白化大鼠能够可靠地区分应激大鼠和非应激大鼠的气味。五只动物学会了在将应激大鼠笼中的空气引入测试隔间时中断正在进行的反应，而在引入非应激大鼠的空气时继续做出反应。这种辨别似乎并不依赖于对个体大鼠气味的识别。
