抄録

To examine how rapidly, and to what extent, humans obtain sufficient information for searching during fixation, we experimented with visual search by masking the subject's central vision at various onsets and sizes after he had fixated there. The subjects counted circles embedded in distractors. From the results, we learned that, in an area of 4.2 degrees, sufficient visual information could be acquired in 33 ms. The oculomotor control system was not affected by masking. The distribution of the fixation duration varied according to the onset of masking. suggesting that eye movements were quickened by the masking of central vision, and saccades occurred about 130 ms after at the onset of masking.
