We have recently developed a new motion display in which the monocular and dichoptic motion components move in opposite directions (Hayashi et al. 2007). In the present paper, we estimated the difference between the integration times required to detect the dichoptic motion and monocular motion by changing the duration of the stimulus. The results showed that monocular motion perception becomes more dominant as the stimulus duration becomes shorter, indicating that the detection of dichoptic motion is relatively slow process that requires a longer integration time compared with the process used to detect monocular motion.
