Information on motion is important for the determination of the three-dimensional (3-D) structure of the environment for both human and non-human primates. For example, if a person were to close one eye and look at an evenly illuminated, irregularly shaped object, he would be unlikely to guess its shape correctly. But if the object is moved about, the correct shape immediately becomes apparent. Little is known about how the primate visual system actually does this, although various theories have been proposed. We have developed novel, highly controlled motion stimuli to use with psychophysical and physiological techniques to study how 3-D structure is obtained from motion. We show that the Rhesus monkey can detect 3-D structure from motion in the same way as human subjects. Furthermore, the dependence of both species on certain parameters of the display shows that information is integrated both spatially and temporally for this higher visual function.
对于人类和非人类灵长类动物而言，运动信息对于确定环境的三维（3-D）结构至关重要。例如，如果一个人闭上一只眼睛，看着一个均匀照明、形状不规则的物体，他不太可能正确猜出它的形状。但是，如果物体四处移动，其正确形状会立即变得明显。尽管已经提出了各种理论，但对于灵长类动物视觉系统实际上是如何做到这一点的，人们却知之甚少。我们开发了新颖的、高度可控的运动刺激，用于结合心理物理学和生理学技术，以研究如何从运动中获取三维结构。我们发现恒河猴能够以与人类受试者相同的方式从运动中检测三维结构。此外，这两个物种对显示的某些参数的依赖性表明，对于这种高级视觉功能，信息在空间和时间上都是整合的。
