正交光栅，二分法提出，不融合成一个单一的光栅。每一部分都被看到，而其他部分则在不稳定的感知中被抑制（双眼竞争）。然而，之前已经注意到，如果光栅短暂地闪烁，它们将看起来融合成格子或棋盘图案。报道了三个实验，其目的是更清楚地定义这种效应的空间和时间参数，希望这将导致更好地了解正常的显性和抑制机制。刺激出现融合，如果闪光小于150毫秒。效果是独立的空间频率和亮度的实质性变化。如果间隔小于约150 ms，则单独出现融合的闪光会产生竞争。间隔大于150 ms会产生持续的异常融合。可能的机制进行了讨论。
Orthogonal gratings, presented dichoptically, do not fuse into a single percept. Parts of each are seen while other parts are suppressed in an unstable perception (binocular rivalry). However, it has been previously noted that, if the gratings are briefly flashed, they will appear to fuse into a plaid or checkerboard pattern. Three experiments are reported which have been designed to define more clearly the spatial and temporal parameters of this effect in the hope that this would lead to better understanding of the normal mechanisms of dominance and suppression. Stimuli appear fused if flashed for less than 150 ms. The effect is independent of substantial changes in spatial frequency and luminance. Single flashes that appear fused when presented in isolation produce rivalry if separated by intervals less than about 150 ms. Intervals greater than 150 ms produce continued abnormal fusion. Possible mechanisms are discussed.
