Three experiments were designed to determine the effects of early color experience on the formation of hue dimension in chicks. In each experiment, one group of chicks was raised in monochromatic light and a second group in white. After two weeks of rearing, they were trained in a colored light (+) vs. white light (-) successive discrimination task, and given generalization tests with regard to the wavelength in a Skinner box. In generalization tests, monochromatically reared subjects showed flatter gradients than the other groups, and longer monochromatic rearing produced flatter gradients. These results suggest that chicks have an innate basis for ordering stimuli of different wavelengths along the hue dimension.
