当用眼睛跟踪物体时，对该物体和其他物体的运动的真实感知需要大脑考虑并补偿眼睛的运动。在这里，我探讨的版本和聚散眼球运动对三维（3-D）运动知觉的影响。在证明了眼动补偿可以检测小物体的深度移动差，我开发了两个模型的眼动和视觉信号如何在3-D运动方向的感知过程中相互作用。第一个模型假设视觉系统的目标是形成一个明确的表示三维运动。从第二个实验的结果，在3-D运动方向的判断，我表明，这个模型只能举行几乎完美的3-D运动补偿，从第一个实验的结果相矛盾。第二个模型假设一个更简单的战略，估计3-D运动方向，根据最近的实验工作。它预测，补偿的聚散度是不需要的，因为3-D运动的Z分量是不需要的方向判断，与实验结果一致。这表明，对于3-D运动方向辨别和角度判断，不使用来自聚散度的视网膜外信号。
When an object is tracked with the eyes, veridical perception of the motion of that object and other objects requires the brain to take account of and compensate for the eye movement. Here, I explore the effects of version and vergence eye movements on three-dimensional (3-D) motion perception. After demonstrating that eye movement compensation can be poor for detecting small objects moving in depth, I develop two models for how eye movement and visual signals may interact during the perception of 3-D motion direction. The first model assumes that the visual system is aiming to form an explicit representation of 3-D motion. From the results of a second experiment, on 3-D motion direction judgements, I show that this model could only hold with almost perfect 3-D motion compensation, contradicting the results from the first experiment. A second model assumes a much simpler strategy for estimating 3-D motion direction, based on recent experimental work. It predicts that compensation for vergence is not required because the Z-component of 3-D motion is not needed for direction judgements, consistent with the experimental results. This suggests that, for 3-D motion direction discrimination and angle judgements, extraretinal signals from vergence are not used.
