TL;DR
It is suggested that the addition of motion information overcomes the stereo distance scaling problem, and when incongruent combinations of disparity and motion were used, results did not match predictions of a number of combination theories.
Abstract
A global shape judgement task was used to investigate the combination of stereopsis and kinetic depth. With both cues present, there were no distortions of shape perception, even under conditions where either cue alone did show such distortions. We suggest that the addition of motion information overcomes the stereo distance scaling problem. However, when incongruent combinations of disparity and motion were used, the results did not match predictions of a number of combination theories. These data could be described by a model which used weighted linear combination after correctly scaling disparities for viewing distance. When the motion cue was weakened by presenting only two frames of each motion sequence, stereo was weighted more heavily.

241 Citations1992JP Roy, Hidehiko Komatsu +1 more
The disparity characteristics of cells in the dorsomedial MST are those expected of a system serving primarily coarse rather than fine stereopsis, and the correlation between disparity selectivity and direction selectivity in these neurons, as well as their other properties, suggests a role in signaling the direction of self-motion of the observer through the environment.

The results show that MST cells, but not MT cells, are selective for elementary flow components (EFCs) alone or their combination with translation, and that position invariance as observed in MST is compatible with an input arrangement from MT cells matching the selectivity of MST neurons.

170 Citations1988Nicola Bruno, James E. Cutting
Grouped and individual results of the one direct and two indirect scaling tasks suggest that perceivers use these sources of information in an additive fashion, which suggests independent use of information by four separate, functional subsystems within the visual system, here called minimodules.

Under reduced conditions of observation, the perception of egocentric distance is determined by a composite of the tendency to see objects as near and residual oculomotor cues of distance, which affects the perceived relative depth produced by binocular disparity between points of light.
