[Spatial properties on the contralateral suppressive field in binocular rivalry (author's transl)]

This paper was to examine the spatial extent of the Contralateral Suppressive Field by using a probe stimulus (20' in diameter) method. It was found that (a) the suppressive effect, measured by frequency of phenomenal disappearance of the probe stimulus, declined sharply in proportion to the distance from the contour of the suppressor, and it declined more sharply near the center of the visual field and (b) the same effect increased in proportion to the contrast of the suppressor, but was independent of the width of the suppressor.
