Early color deprivation and subsequent color vision in a dichromatic monkey

Vision Res. 1987;27(11):2009-13. doi: 10.1016/0042-6989(87)90064-2.


A squirrel monkey (Saimiri sciureus) was reared for the first 4 months of life in a dim, colorless environment. Following an additional 10 months of normal visual experience, tests of color vision and spectral sensitivity were run on this animal and a control subject. The results suggest that the adult expression of dichromatic color vision does not depend on color experience during the first 4 months of life.
