We used binocularly deprived cats (BD cats), control cats reared in the laboratory with open eyes (C cats) and normal wild cats (N cats). In stage 1, the cats were trained to discriminate a black ping-pong ball and a 3-dimensional cross of the same size and color for food reward. The BD cats learned slower than N cats. The difference between BD cats and C cats was statistically insignificant. A comparison of these data and previous data on discrimination of corresponding 2-dimensional black patterns (disk and cross) show that in discrimination learning the 3-dimensionality of stimuli is helpful for N cats, but not for BD cats. Thus, the objects and their patterns are for BD cats highly similar. In stage 2, the objects were replaced by corresponding 2-dimensional patterns (disk and cross). Pattern discrimination was learned slower by BD cats than by N cats. Thus, the objects and their patterns are for BD cats certainly not identical and BD cats are deficient in discrimination transfer of even highly similar pairs of visual stimuli.
我们使用了双眼剥夺猫（BD猫）、在实验室中睁眼饲养的对照猫（C猫）和正常的野猫（N猫）。在第一阶段，训练这些猫区分一个黑色乒乓球和一个尺寸及颜色相同的三维十字架以获取食物奖励。BD猫比N猫学习得慢。BD猫和C猫之间的差异在统计学上不显著。将这些数据与之前关于区分相应二维黑色图案（圆盘和十字架）的数据进行比较表明，在辨别学习中，刺激的三维性对N猫有帮助，但对BD猫没有帮助。因此，物体及其图案对BD猫来说非常相似。在第二阶段，将物体替换为相应的二维图案（圆盘和十字架）。BD猫学习图案辨别比N猫慢。因此，物体及其图案对BD猫来说肯定不一样，并且BD猫在即使是高度相似的视觉刺激对的辨别转移方面存在缺陷。
