Experience-Dependent Color Constancy in Guppies(Poecilia reticulata)

[摘要] We investigated the ability to recognize thecolor of surfaces in fish (Poecilia reticulata),bred from birth in conditions of artificial lightwith constant spectral content. The capacity forcolor constancy significantly deteriorated whencompared that to the control group. Furtheralteration of lighting conditions and transferinto natural daylight conditions restored thesuppressed function to its normal level. Wesuggest that the color constancy functionbelongs in the visual system-response functions,the full development of which requires theaccumulation of individual visual experience.
