Perceptual grouping contributes to the resolution of visual ambiguity of multiple spatially separate regions in view by enhancing their perceptual similarity. Here, the same ambiguous neural representations are shown also to enhance perceived dissimilarity among the regions. Two separated equiluminant gratings were made ambiguous by introducing rivalry for one of two of their features: orientation or chromaticity. Observers perceived two gratings (above and below fixation) to be different in both color and orientation more often than chance. Overall, a disambiguating process was found to select often for maximal perceived dissimilarity between two objects.

在树上看到果实：增强了多个模糊神经表征的感知差异。

感知分组通过增强多个空间分离区域的感知相似性，有助于解决多个空间分离区域的视觉歧义。在这里，还显示了相同的模棱两可的神经表征以增强区域之间的感知差异。通过为其两个特征之一引入竞争，两个分离的等光光栅变得模糊不清：方向或色度。观察者认为两个光栅（固定上方和下方）在颜色和方向上都不同，而不是偶然。总的来说，发现消歧过程经常选择两个对象之间的最大感知差异。
