The study explored the achromatic-color determinants of grouping of uniform surfaces. The stimuli were a set of separate uniform achromatic disks on either a uniform or a bipartite achromatic background. The participants rated the salience of grouping of these disks for different combinations of stimulus luminances. The results show that achromatic color similarity alone could not sufficiently explain the pattern of obtained factorial curves but this factor coupled with the factor of surface segregation could. Luminance contrast similarity per se was found to be unimportant for grouping.
本研究探讨了均匀表面分组的非彩色决定因素。刺激物是一组单独的均匀或双部分非彩色背景上的均匀非彩色圆盘。参与者对这些圆盘在不同刺激亮度组合下的分组显著性进行了评分。结果表明，仅非彩色颜色相似性不能充分解释所获得的阶乘曲线的模式，但该因素与表面分离因素相结合可以。本身，亮度对比度相似性对于分组并不重要。
