Wavelength-discrimination thresholds were measured with stimulus durations of 8, 500, and 2000 msec for test wavelengths of 420 to 630 nm at equal luminance of 100 Td. With the short duration of 8 msec, the discrimination thresholds increased for most wavelengths, but they decreased for the wavelengths near 460 nm. This short-duration wavelength-discrimination function was found to be quite different in shape from that at 2000 msec but similar to one at a low-luminance level of 2.5 Td at 500 msec. Hue, saturation, and brightness of short-duration monochromatic stimuli were also estimated by a color-naming procedure. Changes in color appearance produced by a short stimulus duration were consistent with the tendency that was characterized as tritanopic in previous studies. However, the present results on color discrimination do not necessarily support this tritanopic effect. A possible explanation is discussed.
在100特熙提的均匀亮度下,测量了刺激持续时间为8、500和2000毫秒时,420至630纳米测试波长的波长辨别阈值。在8毫秒的短持续时间下,大多数波长的辨别阈值增加,但在460纳米附近的波长处辨别阈值降低。发现这种短持续时间的波长辨别函数在形状上与2000毫秒时的函数有很大不同,但与500毫秒时2.5特熙提的低亮度水平下的函数相似。还通过颜色命名程序估计了短持续时间单色刺激的色调、饱和度和亮度。短刺激持续时间产生的颜色外观变化与先前研究中被表征为蓝色弱的趋势一致。然而,目前关于颜色辨别的结果并不一定支持这种蓝色弱效应。讨论了一种可能的解释。
