S tabell B. & S tabell U. Chromatic rod vision. IV. Time between pre‐and test‐stimulation varied. Scand. J. Psychol ., 1972, 13 , 141–144.—The scotopic contrast hue was determined as a function of time between pre‐and test‐stimulation. As the interval increased, the scotopic hue was found to change from orange toward yellow in the 440–475 nm region of pre‐stimulation and from violet‐blue toward violet in the 550–595 nm region. It is concluded that (1) depending on wavelength of pre‐stimulation, the processes in the red‐green substance may revert to the mid‐valued state faster or slower than the processes in the yellow‐blue substance, and (2) the red/blue ratio of the violet hue which has to be added to the additive opponent hue to produce the scotopic contrast hue, may change as a function of time between pre‐ and test‐stimulation.
