Discrimination of colours was studied using choice conditioning paradigm (one of a pair of colour stimuli) in carps. Matrix of probabilities of instrumental reactions (catching a bead) was constructed by the results of eight experimental sessions with successive reinforcement of one of the eight colours. It was processed by factor analysis. The spherical structure of carp's perceptual colour space revealed by factor analysis was similar to that of monkeys and humans. Four eigenvectors which constituted four-dimensional Euclidean hypersphere corresponded to excitation of four colour-encoding neuronal channels, i.e., red-green, blue-yellow, bright and dark.
利用选择条件范式（一对颜色刺激中的一种）对鲤鱼的颜色辨别进行了研究。通过对八种颜色之一进行连续强化的八次实验结果，构建了工具性反应（捕捉珠子）的概率矩阵。对其进行了因子分析。因子分析揭示的鲤鱼感知颜色空间的球形结构与猴子和人类的相似。构成四维欧几里得超球体的四个特征向量对应于四种颜色编码神经元通道的兴奋，即红-绿、蓝-黄、明和暗。
