Abstract

Hue-naming was used in conjunction with a probe-flash procedure to determine the time-course of rod-mediated effects on hue appearance across the spectrum. Two types of rod influence on hue are distinguishable on the basis of differences in both spectral specificity and time course of effect: (1) a "faster" rod influence enhances green relative to red and (2) a "slower" rod influence enhances short-wavelength red relative to green and blue relative to yellow. The results show that there are separable rod hue biases that operate over different time courses and that the overall rod influence on hue appearance depends importantly on the temporal properties of the stimuli, presumably because rods interact in different ways with different portions of the neural pathways that mediate human color vision.

摘要

色调命名与探测闪光程序相结合，用于确定视杆细胞介导的对整个光谱色调外观影响的时间进程。基于光谱特异性和效应时间进程的差异，可以区分视杆细胞对色调的两种影响：（1）“较快的”视杆细胞影响相对于红色增强绿色；（2）“较慢的”视杆细胞影响相对于绿色增强短波红色，相对于黄色增强蓝色。结果表明，存在可分离的视杆细胞色调偏差，它们在不同的时间进程中起作用，并且视杆细胞对色调外观的总体影响重要地取决于刺激的时间特性，大概是因为视杆细胞与介导人类色觉的神经通路的不同部分以不同方式相互作用。
