When cats and monkeys are deprived of specific stimuli during an early sensitive period the development of their visual system is known to be affected. In pigeons, pattern discrimination learning has been shown to be affected by monocular deprivation [2]. Our study was set up to examine whether colour discrimination learning could be affected by colour deprivation. Young pigeons were reared under restricted colour illumination for at least 3 months after hatching so as to obtain a group bred under red illumination, one bred under blue illumination and a control group. After this period several psychophysical tests were used to test the pigeons' sense of colour. No significant difference was found between the 'deprived' birds and the controls. The spectral sensitivity, determined with the help of the ERG, did not differ for the three groups. We conclude that early colour deprivation does not affect visual development in the pigeon.
当猫和猴子在早期敏感期被剥夺特定刺激时，已知它们的视觉系统发育会受到影响。在鸽子中，模式辨别学习已被证明会受到单眼剥夺的影响[2]。我们开展这项研究是为了检验颜色辨别学习是否会受到颜色剥夺的影响。幼鸽在孵化后至少3个月内在受限的颜色光照下饲养，从而得到一组在红色光照下饲养的鸽子、一组在蓝色光照下饲养的鸽子以及一个对照组。在此期间过后，使用了几种心理物理学测试来检测鸽子的颜色感知。在“被剥夺”组的鸽子和对照组之间未发现显著差异。借助视网膜电图测定的光谱敏感度在三组之间并无不同。我们得出结论，早期颜色剥夺不会影响鸽子的视觉发育。
