观察者观看长时间（1-2秒）的单眼刺激。在刺激偏移之后，存在暗刺激间隔（ISI）。在ISI之后，同时向双眼呈现短暂的测试闪光。对于小于100-200 msec的ISI，仅看到受刺激眼对侧的测试闪光。在同侧眼睛中没有看到测试闪光。对于200-1000 ms的ISI，对侧测试闪光比同侧闪光更清晰和完整（实验1和2）。初始和同侧测试闪光不需要在空间上相似。初始刺激可以是暗淡的，但必须长于150毫秒（实验3）。实验3排除了前掩蔽或光适应作为解释。该效应相对独立于测试闪光的长度（实验4）。这些结果可以用双眼竞争的已知性质来解释，并加强了竞争行为非选择性的假设（Fox et Check，1968），独立于空间频率，亮度或方向等因素。
An observer viewed a long (1-2 s) monocular stimulus. Following stimulus offset, there was a dark interstimulus interval (ISI). After the ISI, brief test flashes are presented to both eyes simultaneously. For ISIs less than 100-200 msec, only the test flash contralateral to the stimulated eye is seen. The test flash in the ipsilateral eye is not seen. For ISIs of 200-1000 ms, the contralateral test flash is seen more clearly and completely than the ipsilateral flash (experiments 1 and 2). The initial and ipsilateral test flash need not be spatially similar. The initial stimulus can be dim, but must be longer than 150 msec (experiment 3). Experiment 3 precludes forward masking or light adaptation as explanation. The effect is relatively independent of the length of the test flash (experiment 4). The results can be explained in terms of the known properties of binocular rivalry, and reinforce the hypothesis (Fox et Check, 1968) that rivalry acts nonselectively, independent of factors such as spatial frequency, luminance or orientation.
