When the right eye's target is the left eye's distracter and vice versa, orientation-defined search is impossible unless, as we show here, the elements are close together. More than 1s was required to find inverse-cyclopean texture boundaries when elements were arranged on a 16 x 16 grid. Less than 250 ms was required for a 24 x 24 grid covering the same area. The conventional view is that binocular rivalry requires at least 200 ms to develop, but our results suggest a more rapid access to monocular signals. We call this rapid form of access "proto-rivalry."
当右眼的目标是左眼的干扰物，反之亦然时，除非元素靠得很近（正如我们在此所展示的），否则基于方向定义的搜索是不可能的。当元素排列在16×16的网格上时，找到反独眼纹理边界需要超过1秒。对于覆盖相同区域的24×24网格，所需时间不到250毫秒。传统观点认为双眼竞争至少需要200毫秒才能形成，但我们的结果表明对单眼信号的获取更为迅速。我们将这种快速的获取形式称为“原始竞争”。
