It is known for binocular stereoscopic vision that the kind of disparity and the size of the amount of disparity will in°uence at time until perceiving the depth after uniting. Similarly, the kind of disparity and the size of the amount of disparity are considered to in°uence also time taken to unite. That is, it is thought that as the quantity of disparity is small, so the time taken to 〜nd and unite a correlated point becomes short and when there is no disparity among both eyes, the time required in order to unite becomes the shortest. Then, this research examined what thing it was with the "stimulus without disparity" for a binocular stereoscopic system, especially the subsystem that searches for a correlated point. As a stimulus that does not have disparity among both eyes, random-dot distributed on a geometric horopter side, random-dot distributed on an experical horopter side, and random-dot distributed on a fronto-parallel plane side, were assumed and the time characteristic when detecting the correlated point of each RDS was investigated. The experiment was conducted in dark using the Wheatstone type stereoscope. Random-dot-stereogram of the curved surface described previously and the dummy stimulus which includes a uncorrelated point which cannot be united as distractor were shown together up and down to the subject, and the stimulus which can be united carried out forcible selection of either. Consequently, it checked that the time when detecting the correlated point of RDS distributed on a geometric horopter side became the shortest.
