一些研究表明，视觉运动会扭曲感知持续时间：快速移动的刺激持续时间被判断为比静止或缓慢移动的刺激持续时间长。然而，目前还不清楚运动处理的哪个阶段参与了感知持续时间的明显扩张。在这项研究中，使用一个二维图案运动的格子作为刺激，我们系统地操纵的图案和组件运动的格子的速度，以检查哪些运动信息影响感知的持续时间的格子刺激。实验1发现，感知持续时间增加与模式的速度，即使组件的速度是恒定的。实验2和3表明，感知持续时间是不变的，即使组件的速度增加，只要模式的速度是相同的。实验4使用静态和移动格子，并证实实验1 - 3的结果反映了运动引起的持续时间扩张，而不是持续时间压缩。这些结果表明中颞区的高阶视觉加工可能在运动诱导的时程扩张中起重要作用。
Several studies have shown that visual motion distorts perceived duration: The duration of fast-moving stimuli is judged to be longer than the same duration of stationary or slow-moving stimuli. However, it is still unclear which stages of motion processing are involved in this apparent dilation of the perceived duration. In this study, using a two-dimensional pattern motion of a plaid as a stimulus, we systematically manipulated the speed of pattern and component motions of the plaid to examine which motion information influences the perceived duration of the plaid stimuli. Experiment 1 found that perceived duration increased with pattern speed, even though component speed was constant. Experiments 2 and 3 revealed that perceived duration was unchanged, even though component speed increased, as long as the pattern speed was identical. Experiment 4 used both static and moving plaids and confirmed that the results of Experiments 1-3 reflected duration dilation, not duration compression, induced by motion. These results suggest that higher order visual processing in the middle temporal area may play an important role in motion-induced duration dilation.
