诱导运动是一种错误的印象，即物理上静止的物体在其他真正移动的物体存在时会移动。在这项研究中，我们调查了这种运动错觉的深度维度。我们提出了三个相关的问题，如下：（1）刺激中的哪些线索是造成这种深度运动错觉的原因？(2)这种错觉的大小会受到聚散眼球运动的影响吗？（3）眼动对深度运动和额平行平面运动的影响是否不同？为了回答这些问题，我们测量了主观平稳性的点。观察者观察了一个在深度上振荡的诱导器目标和一个位于其正上方的测试目标。测试目标与诱导器同相或异相移动，但幅度较小。观察员必须指出测试目标和诱导目标是同相还是异相运动。他们被要求要么盯着测试目标，要么盯着诱导物。对于由双眼视差和视网膜大小变化或单独由双眼视差产生的深度运动，我们发现当眼睛跟随诱导器时，主观平稳性发生在诱导器幅度的约40-45%处。当眼睛盯着测试目标时，偏差降低了10倍，达到4%左右。当大小变化是深度运动的唯一线索时，就没有虚幻的运动了。当眼睛被保持在一个诱导器在frontoparallel平面移动，诱导运动是相同的顺序，诱导运动的深度，即约44%。当诱导运动在额平行平面内时，我们发现当眼睛保持在测试目标上时，感知平稳性发生在诱导器幅度的约23%处。
Induced motion is the false impression that physically stationary objects move when in the presence of other objects that really move. In this study, we investigated this motion illusion in the depth dimension. We raised three related questions, as follows:(1) What cues in the stimulus are responsible for this motion illusion in depth?(2) Is the size of this illusion affected by vergence eye movements? And (3) are the effects of eye movements different for motion in depth and for motion in the frontoparallel plane? To answer these questions, we measured the point of subjective stationarity. Observers viewed an inducer target that oscillated in depth and a test target that was located directly above it. The test target moved in phase or out of phase with the inducer, but with a smaller amplitude. Observers had to indicate whether the test target and the inducer target moved in phase or out of phase with one another. They were asked to keep their eyes either on the test target or on the inducer. For motion in depth, created by binocular disparity and retinal size change or by binocular disparity alone, we found that when the eyes followed the inducer, subjective stationarity occurred at approximately 40–45% of the inducer's amplitude. When the eyes were kept fixated on the test target, the bias decreased tenfold to around 4%. When size change was the only cue to motion in depth, there was no illusory motion. When the eyes were kept on an inducer moving in the frontoparallel plane, induced motion was of the same order as for induced motion in depth, namely, approximately 44%. When the induced motion was in the frontoparallel plane, we found that perceived stationarity occurred at approximately 23% of inducer's amplitude when the eyes were kept on the test target.
