Classical theories of brightness and lightness induction have largely been stated in terms of two opposing influences from the surround: contrast and assimilation. In fact, these two effects are part of a more complex but reproducible and mathematically well-defined statistical process in which both low-level neural constraints and top-down cognitive judgments contribute to the measured percept. Here we test a particular model of this process based on edge integration theory with contrast gain control. We employed a brightness matching technique based on disk-annulus stimuli and showed that we can account for our results with a quantitative model in which the contrast polarity of the stimulus plays a critical role.
对比和同化。事实上，这两种效应是一个更复杂但可重复且数学上定义明确的统计过程的一部分，在这个过程中，低级神经约束和自上而下的认知判断都对测量到的感知有贡献。在这里，我们基于具有对比度增益控制的边缘整合理论测试了这个过程的一个特定模型。我们采用了一种基于圆盘-圆环刺激的亮度匹配技术，并表明我们可以用一个定量模型来解释我们的结果，在这个模型中，刺激的对比极性起着关键作用。
