这些实验与阈值亮度感知的经典研究类似，波长变化取代强度变化。在整个光谱中，灵敏度-vs.-用于感知波长调制的频率曲线与用于亮度调制的类似（De Lange）曲线的形状完全不同。这些曲线被解释为不同的衰减特性的神经机制的基础上的刺激波长和强度的阈值变化的知觉分别的描述。经典的bipartite场方法给出的信息很少的波长歧视的动力学。我们报告的波长歧视曲线的形状是刺激重复频率的函数。当刺激频率从5 Hz降低到0.5Hz时，黄光最小值受影响不大，而蓝绿光最小值则从500 nm移到480 nm以下。我们的数据表明，动态波长鉴别曲线不能直接向前与CIE数据。
These experiments are analogous with classical studies of threshold luminance perception, with wavelength changes replacing intensity changes. Throughout the spectrum the shapes of the sensitivity-vs.-frequency curves for the perception of wavelength modulation are quite different from the shapes of the analogous (De Lange) curves for luminance modulation. These curves are interpreted as descriptions of the different attenuation characteristics of the neural mechanisms which underlie the perception of threshold changes of stimulus wavelength and intensity respectively.The classical bipartite-field method gives little information as to the dynamics of wavelength discrimination. We report that the shape of the wavelength discrimination curve is a function of stimulus repetition frequency. Although the yellow minimum is little affected, the blue-green minimum shifts from 500 nm to below 480 nm when stimulus frequency is reduced from 5 Hz to 0.5 Hz.Tentative attempts are made to use the data as fresh tests of colour vision. Our data indicate that dynamic wavelength discrimination curves cannot straight forwardly be related to CIE data.
