In some special situations, we have size and distance perception which were disagree with the reality, that we called illusions. The purpose of the research is to debate that in the dichoptic presentation, will manipulate different kinds of depth cues effecting the judgments of size and distance ? The purpose of experiment 1 was to access the effects of task types, depth cues and location of moons. The results show that task types and depth cues may not cause an effect to the judgments of the subjects, but the location of moons does. In experiment 1, size-distance invariance hypothesis(SDIH) was been supported. But we can''t find measurable relationship between the distance and size perceptions. The purpose of experiment 2 was to access the effects of task types and depth cues. The results show that depth cues may not cause an effect to the judgments of the subjects. In the dichoptic presentation, the subjects may judge the distance better. In spite of the effects of SDIH is very strong, but we still can''t predict it through the formula absolutely.
