光学运动和视网膜血流的梯度被认为是感知空间布局的重要信息来源。然而，在侧视差的情况下，流畅的眼球运动对视网膜流场的复杂影响以及已知的视觉系统对绝对运动的不敏感性表明，光运动本身不能提供准确感知深度关系方向(符号)的基础。他们最多只能提供“未签名”深度的信息。对15名大学生和教职员工进行的两项实验的结果支持这样一种观点，即不同的光学运动会导致物体深度分离的强烈印象，但确定远近关系通常取决于其他信息来源。(参考文献18)
Optical motions and gradients of retinal flow have been assumed to be an important source of information for the perception of spatial layout. In the case of lateral parallax, however, the complicating effects of smooth eye movements on retinal flow fields and the known insensitivity of the visual system to absolute motion suggest that optical motions alone cannot provide the basis for accurate perception of the direction (sign) of depth relations. At most they can provide information for" unsigned" depth. Results of 2 experiments with 15 university students and staff members support the view that differential optical motions result in a strong impression of separation of objects in depth, but that the determination of near–far relations normally depends on other sources of information.(18 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
