Abstract

In the research we used "Method of Constant Stimuli". Stimuli were presented numerous times in random order and the subject reports whether he/she could detect them. In Stage 1, we found the speed smudges disappear is Ratio 10:16 > Ratio 10:14 > Ratio 10:12 > Ratio 10:12, no matter when we right declined the squares or when we rotated the squares. In Stage 2, we found when the style of squares is right declined, the speed smudges disappear was Ratio 10:12 > Ratio 10:11; when the style of squares was down declined, the speed smudges disappear was Ratio 10:11 > Ratio 10:12. In Stage 3 we found that no matter rotated or right declined or down declined or rotated the squares, the speed smudges disappeared was Ratio 10:11 < Ratio 10:10 and Ratio 10:12. Then we can find the effect trend ratio on stopping Hermann Grid may be a (symbol--see manuscript) mark. It means the speed smudges disappear is Ratio 10:16 > Ratio 10:14 > Ratio 10:12 > Ratio 10:10 > Ratio 10:11.
