我们建立了存在纯粹的立体运动感应，即感知深度运动诱导成一个固定的视差目标的视差变化在周围区域。刺激是由目标和环绕物组成的动态自动立体图，两者均由水平的圆盘线组成。我们通过以下方式探索了立体运动诱导过程：（i）直接估计感知的移动距离，（ii）补偿目标运动的消除技术，以及（iii）将补偿运动扩展到零点以外的区域。增加补偿立体运动的目标减少了诱导运动的经验，一个零点。在取消点之外，获得了两个令人惊讶的结果;目标中的感知运动增加，而环绕立体运动感知在宽范围的视差变化上几乎被抑制（交互立体运动抑制）。目标/周围的相互作用的模型中开发的立体运动感知和错觉的动态组织原则的背景下。
We establish the existence of purely stereoscopic motion induction, ie, perceived depth motion induced into a fixed-disparity target by disparity changes in a surround region. The stimuli were dynamic autostereograms consisting of a target and a surround, both consisting of horizontal lines of discs. We explored the stereomotion induction process by (i) direct estimation of the perceived distance moved,(ii) a cancellation technique with compensatory target motion, and (iii) extension of the compensatory motion into the zone beyond the null point. Adding compensatory stereomotion to the target reduced the induced motion experience to a null point. Beyond the cancellation point, two surprising results were obtained; perceived motion in the target increased, while the surround stereomotion perception was almost suppressed over a wide range of disparity changes (reciprocal stereomotion suppression). A model of the target/surround interactions was developed in the context of dynamic organization principles operating in stereomotion perception and misperception.
