Reasoning abilities of Norway rats were studied in Revecz-Krushinskiĭ test. In this test 12 opaque plastic cylinders were placed in a row. Rats obtained the bait (sunflower seeds) after tipping the goal cylinder (from the feeder situated under it) independently of the number of one tipped before. Positions of the baits were changed in the following order: the cylinder No 1 in the first trial, No 2--in the second and so on up to the twelfth one. Rats were tested 3 times (12 trials, once a week) in a rectangular box with a starting chamber and a working part with a special device which excluded the influence of olfactory stimuli. Solution scores demonstrated that rats chose cylinders in the nonrandom manner and their behaviour scores were similar to those of crows and monkeys. Analysis of errors and strategies of behaviour of rats showed that quick improvement of feeding was at least partly determined by easy acquisition of recent food positions (i.e., the algorithm of shifting).
在列韦茨-克鲁申斯基测试中研究了挪威大鼠的推理能力。在该测试中，12个不透明塑料圆柱体排成一排。大鼠通过倾斜目标圆柱体（从位于其下方的喂食器中）获得诱饵（葵花籽），而与之前倾斜的圆柱体数量无关。诱饵的位置按以下顺序改变：第一次试验中是1号圆柱体，第二次是2号圆柱体，依此类推，直到第12个圆柱体。在一个带有起始室和工作部分的矩形盒子中对大鼠进行了3次测试（12次试验，每周一次），该盒子配有一个特殊装置，可排除嗅觉刺激的影响。解决方案得分表明，大鼠以非随机方式选择圆柱体，其行为得分与乌鸦和猴子的相似。对大鼠行为错误和策略的分析表明，进食的快速改善至少部分取决于对近期食物位置的轻松获取（即转移算法）。
