与静态刺激相比，运动刺激的持续时间被高估（运动诱导的持续时间扩张）。相反，当参与者在视觉上适应了移动刺激后，他们低估了接下来的移动刺激的持续时间（适应引起的持续时间压缩）。这两个运动相关的时间失真还没有在一项研究中使用相同的刺激进行检查，仍然不知道这些现象是否具有相似的特征。在这里，我们使用亮度调制和等亮度色度调制的运动刺激，并测试这些类型的运动是否会引起持续时间的感知失真。由于在相同的物理速度下，等亮度颜色运动被感知为比亮度运动慢，因此两种类型的运动的速度在物理上相同（实验1）或在感知上匹配（实验2）。我们发现，当运动速度是物理上相同的，亮度运动引起更大的持续时间失真比等亮度颜色运动。当运动速度感知相同时，亮度运动仍然诱导了比等亮度颜色运动更大的运动诱导的持续时间扩张，而亮度运动和等亮度颜色运动诱导了大约相同量的自适应诱导的持续时间压缩。我们还发现，对于这两种效果，亮度运动引起的持续时间失真的量与等亮度颜色运动引起的正相关。这些结果表明，强大的和一致的运动相关的持续时间失真，是共同的亮度运动和等亮度颜色运动的个体差异。
The duration of moving stimuli is overestimated compared to that of static stimuli (motion-induced duration dilation). In contrast, after participants visually adapt to a moving stimulus, they underestimate the duration of a following moving stimulus (adaptation-induced duration compression). These two motion-related time distortions have not been examined using the same stimuli within a study, and it remains unknown whether these phenomena have similar characteristics. Here, we used luminance-modulated and isoluminant chromaticity-modulated moving stimuli and tested whether these types of motion induce perceptual distortions of duration. As isoluminant-color motion is perceived slower than luminance motion at the same physical speed, the speeds of the two types of motion were either physically same (Experiment 1) or perceptually matched (Experiment 2). We found that when motion speeds were physically identical, luminance motion induced larger duration distortions than did isoluminant-color motion. When motion speeds were perceptually identical, luminance motion still induced a larger motion-induced duration dilation than isoluminant-color motion did, while luminance motion and isoluminant-color motion induced approximately the same amount of adaptation-induced duration compression. We also found that, for both effects, the amount of duration distortion induced by luminance motion positively correlated with that induced by isoluminant-color motion. These results indicate robust and consistent individual differences in motion-related duration distortions that are common to luminance motion and isoluminant-color motion.
