Early colour deprivation in a monkey (Macaca fascicularis)

Vision Res. 1985;25(9):1337-9. doi: 10.1016/0042-6989(85)90050-1.


Various forms of selective visual deprivation are known to affect the development of the monkey visual system. In the present study a monkey was born and spent the first three months of its life under red illumination. Despite this colour deprivation, the young monkey learnt to distinguish between colours. Furthermore, the monkeys' increment threshold spectral sensitivity was not affected by the deprivation.
