The extrafoveal spectral sensitivity function was measured during dark adaptation at different intensity levels above the cone plateau of the long-term dark-adaptation curve using both flicker and heterochromatic brightness-matching techniques. During most of the cone-plateau period, the spectral sensitivity function was found to be photopic in form at all the intensity levels employed. In the dark-adapted state, the two psychophysical techniques appeared to measure different processes. Thus, the flicker technique yielded a spectral sensitivity function which was basically scotopic in form at all the intensity levels employed while the spectral sensitivity function obtained with the brightness technique was basically photopic in form. It is suggested that, in a dark-adapted state, both rods and cones contribute to the brightness response at each wavelength over the major portion of the spectrum for a long transitional intensity range when the brightness technique is used. The flicker technique, on the other hand, appears to single out the rod activity.
使用闪烁和异色亮度匹配技术，在长期暗适应曲线的视锥细胞平台之上的不同强度水平下，于暗适应期间测量了中央凹外光谱敏感度函数。在视锥细胞平台期的大部分时间里，在所采用的所有强度水平下，光谱敏感度函数在形式上均为明视觉。在暗适应状态下，这两种心理物理学技术似乎测量的是不同的过程。因此，闪烁技术得出的光谱敏感度函数在所有所采用的强度水平下基本上呈暗视觉形式，而亮度技术获得的光谱敏感度函数基本上呈明视觉形式。有人提出，在暗适应状态下，当使用亮度技术时，在很长的过渡强度范围内，视杆细胞和视锥细胞在光谱的主要部分的每个波长处都对亮度响应有贡献。另一方面，闪烁技术似乎挑选出了视杆细胞的活动。
