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.
以双眼分视方式呈现的正交光栅不会融合成单一的感知。每一个光栅的部分会被看到，而其他部分在不稳定的感知（双眼竞争）中被抑制。然而，之前已经有人指出，如果光栅短暂闪烁，它们会看起来融合成一个格子图案或棋盘图案。本文报告了三个实验，这些实验旨在更清晰地界定这种效应的空间和时间参数，希望这能有助于更好地理解优势和抑制的正常机制。如果闪烁时间少于150毫秒，刺激会显得融合。这种效应与空间频率和亮度的大幅变化无关。单独呈现时看起来融合的单次闪光，如果间隔时间少于约150毫秒，会产生竞争。大于150毫秒的间隔会导致持续的异常融合。文中还讨论了可能的机制。
