The effects of rapid eye movements on perceived duration of time

以往的研究提出，我们使用知觉事件的数量来估计时间的持续时间。本研究首先假设事件的数量会随着小的自动眼球运动(微眼跳)频率的增加而增加，这将导致感知持续时间的增加。我们的实验结果表明，微扫视的频率和感知的持续时间之间没有相关性。然而，它们暗示了凝视位置的变化与感知的持续时间之间的负相关。本研究接下来集中于视觉输入触发(即自动)或自愿启动眼跳的感知持续时间。结果表明，感觉到的持续时间会缩短，特别是当眼跳被自动触发时。

Previous researches proposed that we estimate duration of time using the numbers of perceptual events. The present research first hypothesized that the numbers of events will increase as the frequency of small automatic eye movements(microsaccades) increases, which will cause the increase of the perceived duration of time. The results of our experiments showed no correlation between the frequency of microsaccades and the perceived duration of time. However, they implied the negative correlation between the variety of the position of gaze and the perceived duration of time. The present research next focused on the perceived duration of time when the saccade was triggered by visual input(i. e. automatically) or initiated voluntarily. The results suggested that perceived duration of time is shortened especially when the saccade was triggered automatically.
