This study examined the relationships between autokinetic illusions and eye movements during the illusion was observed. During 90 sec observation period, four subjects were asked to report autokinetic illusions by pushing lap-time-button of a stopwatch while eye activities of the subjects were monitored. Three kinds of eye activities, fixation, saccadic eye movement, and eye blink were identified, and each duration and frequency was measured. Ninety percent of the observation period during reporting autokinetic illusions were the fixation, and time-ratio of the fixation to total observation period differed significantly from that observed under no-reporting of the illusion. In addition, durations of saccadic eye movement and eye blink during no-illusion were significantly longer than those during the illusions. Frequencies of three eye movements reported under the illusion observing period were not significantly different from those under the no-illusion. It is suggested that the most of autokinetic effects occur during fixation, and the illusion is related to some kind of eye movements, actual or suppressed.
