Abstract : The report presents data on the spectral sensitivity of the eye for a baseline condition of 3000 trolands of planckian-radiator (white) light, and a comparison with the eye's sensitivity when 10,000 trolands of a narrow-band radiation from the blue, green or red parts of the spectrum are added to the white light. The results show a quantitatively greater reduction of sensitivity over the spectral region of the added spectral light, which qualitatively appears to take the form of nearly or completely eliminating the peak found in that region of the spectrum under the white-light condition. There is less effect on the adjacent parts of the function. These results begin to suggest spectral mechanisms which have considerably narrower ranges of spectral sensitivity than are shown in rod and isolated-cone photopigment spectral bleaching data. The questions which these results raise with regard to currently proposed general explanations of color and brightness vision are discussed. (Author)
