The effects of rapid eye movements on perceived duration of time

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.
