Two experiments were conducted to examine the effect of fixation choices on the perception of total figure. To restrict the spatial and temporal span of eye fixation, a video editing system and a personal computer were used. In experiment 1, an ambiguous figure divided into six segments was used as material and sixty-two undergraduate students were served as subjects. Segments were presented successively one by one. The effect of segment sequence was significant. In experiment 2, using similar procedure as exp. 1, ten numerical figures were used as materials to control information contained in segments, and response time to identify total figure was measured. Reducing pattern of uncertainty in the sequence determined response time. Two levels in the situation of spatio-temporal integration, short range and long range integration process were discussed.
