当一个人在旋转的球体表面上观察二维平行投影的点时，旋转方向是模糊的，并且随着时间的推移，二维图形的旋转方向是不稳定的。稳定性可以暂时诱导适应三维地球与旋转方向明确指定的立体视差；适应使二维图形向与立体适应相反的方向旋转。这种自适应效应对旋转轴是选择性的，但不是特定于形状的。它确实依赖于由不同方向移动的元素定义的多个深度平面的同时刺激。很明显，关于立体视觉的信息和关于运动结构的信息被整合在大脑的一个共同的神经部位。
When one views a two-dimensional parallel projection of dots on the surface of a rotating globe, the direction of rotation is ambiguous, and the perceived direction of rotation of the two-dimensional figure is unstable over time. Stability can be temporarily induced by adaptation to a three-dimensional globe with a direction of rotation unambiguously specified by stereo disparity; adaptation causes the two-dimensional figure to appear to rotate in the direction oppposite that experienced during stereoscopic adaptation. This adaptation effect is selective for axis of rotation but is not shape-specific. It does depend on simultaneous stimulation by multiple depth planes defined by elements moving in different directions. Evidently information about stereopsis and information about structure from motion are integrated within a common neural site in the brain.
