先前的研究发现，在径向扩张的光流中加入立体信息可以减少矢量的发作和增加矢量的持续时间（Palmisano, 1996 Perception & psychphysics 58 1168 - 1176）。在目前的实验中，立体线索也被发现增加了对深度矢量速度和自我位移的感知——但只有当这些线索与单眼可获得的自我运动信息一致时。立体信息似乎并没有通过增加感知到的最大显示范围或使显示看起来更立体来改善向量。相反，似乎一致的立体光流模式提供了额外的、纯粹的关于矢量速度的双眼信息，这导致了更快/更引人注目的深度自我运动幻觉。
Previous research found that adding stereoscopic information to radially expanding optic flow decreased vection onsets and increased vection durations (Palmisano, 1996 Perception & Psychophysics 58 1168 - 1176). In the current experiments, stereoscopic cues were also found to increase perceptions of vection speed and self-displacement during vection in depth-but only when these cues were consistent with monocularly available information about self-motion. Stereoscopic information did not appear to be improving vection by increasing the perceived maximum extent of displays or by making displays appear more three-dimensional. Rather, it appeared that consistent patterns of stereoscopic optic flow provided extra, purely binocular information about vection speed, which resulted in faster/more compelling illusions of self-motion in depth.
