Abstract

A review of psychophysical experiments was done and the big differences of their results are found. We set a suitable new experiment condition and tried several experiments with some results. Then, a review of neurophysiological experiments was done and a rough hypothesis determining fixation point (according to the situation, the information of producing "saccade" is sent SC from a proper area in the brain.) was proposed and a confirmation experiment was done using "Gestalt collapse of Chinese character" phenomena: when a subject gazes a Chinese character for a long time, he loses the function of understanding it at a time not exceeding 60 sec. We obtained a result that the fixation point moves from the center of the Chinese character to the center of its part region such as its left-hand radical at about 8 sec before the collapse.
