立体视觉是一个复杂的过程，因为感知的深度间隔不仅取决于视网膜视差，而且还取决于距离的线索。因为视差与物距的平方成比例地减小，所以被称为立体深度恒定性的补偿过程通过考虑物距来对深度感知进行必要的校正。这种补偿过程被适应所改变。受试者暴露在人工条件下，差异与距离而不是距离平方成比例减少。深度知觉的变化达到20%。
Stereovision is a complex process because perceived depth intervals depend not only on retinal disparity, but also on cues for distance. Because disparity decreases in proportion to the square of the object distance, a compensation process called constancy of stereoscopic depth makes the necessary correction in the perception of depth by taking object distance into account. This compensation process was altered by adaptation. Subjects were exposed to artificial conditions where disparity decreased in proportion to distance instead of distance squared. Alterations in depth perception amounting to 20% were obtained.
