The influence of depicted illumination on brightness

The striking illusions produced by simultaneous brightness contrast generally are attributed to the center-surround receptive field organization of lower order neurons in the primary visual pathway. Here we show that the apparent brightness of test objects can be either increased or decreased in a predictable manner depending on how light and shadow are portrayed in the scene. This evidence suggests that perceptions of brightness are generated empirically by experience with luminance relationships, an idea whose implications we pursue in the accompanying paper.

由同时性亮度对比（simultaneous brightness contrast）所引发的显著视错觉，通常被归因于初级视觉通路（primary visual pathway）内低级神经元的中心-周边感受野（center-surround receptive field）组织机制。本研究证实，测试物体的表观亮度可根据场景中光影的呈现方式，以可预测的方式升高或降低。该研究证据表明，亮度感知实则通过对亮度关系的经验习得而产生，这一观点的相关内涵将在本配套论文中进一步探讨。
