Previous research has shown that there are two binocular cues that contribute to the perception of motion in depth. One cue consists of the rate of changing disparity (CD) over time and the other consists of interocular velocity difference (IOVD). In the current study, we examined the temporal characteristics of the two cues in determining motion in depth perception. In the study, uncorrelated random dot stereograms (URDS) were used to present displays with IOVD information only, and dynamic correlated random dot stereograms (DRDS) were used to present displays with CD information only. The life time of the random dots was manipulated in both URDS and DRDS display conditions. Observers were asked to judge the direction of motion in depth. The results showed different temporal response curves for displays with CD information as compared to those with IOVD information. This suggests that different temporal characteristics of CD and IOVD information need to be taken into account when investigating stereomotion perception.
