两个交替的框架，每个框架由三个正方形元素组成，被用来研究双频闪运动知觉。双稳态感知得到依赖于交替帧之间的刺激间间隔（ISI）。在短的ISI，只有端到端的元素运动被观察到，并在更高的ISI，只有组运动被感知。结果发现，渐进的ISI依赖于从元素到组运动的过渡取决于元素的大小和帧持续时间。这些依赖关系是可预测的，从系统的影响，这些变量也被称为施加在视觉模式的持久性，表明这种持久性有助于确定哪些视觉感知占主导地位，在频闪运动序列。这些研究结果承担相关的最近试图在概念上将短距离频闪运动感知到短距离频闪运动过程。
Two alternating frames, each consisting of three square elements, were used to study bistable stroboscopic motion percepts. Bistable percepts were obtained which depend on the interstimulus interval (ISI) between the alternating frames. At short ISIs only end-to-end element motion was observed; and at higher ISIs only group motion was perceived. It was found that the progressive ISI-dependent transitions from element to group motion depended on element size and frame duration. These dependencies are predictable from the systemic influence which these variables are known also to exert on visual pattern persistence, indicating that such persistence contributes to determining which percept dominates during bistable stroboscopic motion sequences. These findings bear relevantly on recent attempts to conceptually relate bistable motion percepts to short-range stroboscopic motion processes.
