A series of three experiments was performed to determine the minimum contrast necessary for a grating pattern to engage in binocular rivalry with a dissimilar pattern presented to the other eye. It was found that a pattern at its own contrast threshold can suppress temporarily a contralateral pattern, regardless of the contrast of the latter. In a fourth experiment it was found that a near-threshold pattern is as effective, in terms of the duration of visibility, as one that is four times greater in contrast; only the average duration of suppression varied with pattern contrast. This last set of data extends the findings of others to near-threshold conditions and poses difficulties for models of binocular rivalry based on the notion of reciprocal inhibition.
进行了一系列三个实验，以确定光栅图案与呈现给另一只眼睛的不同图案进行双眼竞争所需的最小对比度。结果发现，处于自身对比度阈值的图案可以暂时抑制对侧图案，而不管后者的对比度如何。在第四个实验中发现，就可见持续时间而言，接近阈值的图案与对比度大四倍的图案一样有效；只有抑制的平均持续时间随图案对比度而变化。最后这组数据将其他人的研究结果扩展到了接近阈值的条件，并给基于相互抑制概念的双眼竞争模型带来了困难。
