通过一个匹配过程，我们研究了直接亮度（或明度）和色度变化（由被匹配区域的调制产生）以及间接亮度和色度变化（由被匹配区域的周围调制产生）的时间特性。直接的亮度和颜色变化的量被发现在0.5 - 8 Hz的范围内研究的时间频率只有轻微的变化，而诱导的变化被发现只发生在低的时间频率，低于约2.5 Hz。随着周围环境的高时间频率调制，诱导的图案似乎闪烁，但不改变亮度或颜色。尽管色度和亮度时间对比敏感度函数非常不同，但颜色和亮度的时间感应曲线非常相似。然而，亮度感应被发现随着环绕调制的增加而近似线性地增加，直到非常高的水平，而颜色感应的量对环绕的调制深度的依赖要小得多。
With a matching procedure, we studied the temporal properties ofdirectbrightness (or lightness) and chromatic changes (produced by modulation of the region being matched) andinducedbrightness and chromatic changes (produced by modulation of the surround of the region being matched). The amount of direct brightness and color change was found to vary only slightly with temporal frequency over the 0.5–8 Hz range studied, whereas induced changes were found to occur only at low temporal frequencies, below about 2.5 Hz. With high temporal-frequency modulation of the surround, the induced patterns appeared to flicker but not to change in brightness or color. Despite the fact that chrominance and luminance temporal contrast sensitivity functions are very different, the temporal induction curves for color and brightness were very similar. However, brightness induction was found to increase approximately linearly with increasing surround modulation up to very high levels, whereas the amount of color induction was much less dependent on the modulation depth of the surround.
