To examine the effect of homogeneity of area in figure-ground organization, we made several variations of Rubin's goblet. Observers were required to judge whether they perceived a goblet or profiles (faces). Our results showed that, when both profiles were the same lightness, the percentage of judgments (goblet vs profiles) were almost equal. When the profiles were different in lightness, so that the homogeneity of the profile areas was broken, observers were more likely to perceive the profiles. When both profile areas had horizontal stripes or concentric circles and the homogeneity of the profile areas was strengthened, those areas tended to be perceived as ground. We concluded that (1) a difference in lightness was sufficient to break up the homogeneity of the profile areas; (2) good continuity was an eminent condition for unifying profile areas as ground.
为了研究图形-背景组织中区域同质性的影响，我们对鲁宾之杯做了几种变体。要求观察者判断他们看到的是一个杯子还是侧面像（脸）。我们的结果表明，当两个侧面像的亮度相同时，判断（杯子与侧面像）的百分比几乎相等。当侧面像的亮度不同，从而破坏了侧面像区域的同质性时，观察者更有可能看到侧面像。当两个侧面像区域都有水平条纹或同心圆，且侧面像区域的同质性增强时，这些区域往往会被视为背景。我们得出结论：（1）亮度差异足以打破侧面像区域的同质性；（2）良好的连续性是将侧面像区域统一为背景的一个重要条件。
