Abstract(in English)	To understand the mechanism of perceptual filling-in, the author examined how the time required for filling-in varied dependent on the pattern difference between the patch(figure)and the backfround(ground). In the experiments, the figure and ground were different in luminance(Exp. 1)or orientation of grating patterns(Exp. 2). As a result, the time for filling-in got longer as the figure-ground difference became larger. Most interestingly, the time changed significantly when the patterns for figure and ground were alternated with each other. The results suggested that perceptual filling-in resulted not simply from the selective fatigue of edge representation, but also from the competition between neural activities representing figure and ground patterns.
