The II5 color mechanism was isolated in two observers with a 667 nm, 200 ms, 1 deg foveal test flash. Stiles's field displacement law and the law of field additivity were tested with increment thresholds upon monochromatic and bichromatic adapting fields. The data of both observers obey the displacement law and exhibit no systematic deviations from additivity. Our results cannot reject the hypothesis that the first log unit of adaptation observed under II5-isolation conditions is determined exclusively by the quantum catch rate of the long-wavelength-sensitive cones.
在两名观察者中，使用667纳米、200毫秒、1度中央凹测试闪光分离出II5颜色机制。用单色和双色适应场的增量阈值测试了斯泰尔斯场位移定律和场叠加定律。两名观察者的数据均符合位移定律，且未表现出与叠加性的系统性偏差。我们的结果不能排除以下假设：在II5分离条件下观察到的第一个对数单位的适应完全由长波长敏感视锥细胞的量子捕获率决定。
