在白色等亮度效应中，放置在方波光栅的黑色和白色条上的测试块的亮度不同。这种错觉引起了人们的强烈兴趣，因为亮度效应的方向与测试片接触的黑色或白色边框的数量无关，或者在其附近。因此，与亮度诱导效应（如同时对比度）不同，白色效应与基于对比度或同化的解释不一致，这些解释仅取决于测试斑块周围黑色和白色的相对量。我们独立地操纵共线和侧翼条的亮度，以研究它们对测试贴片匹配亮度（亮度）的影响。感应光栅为0.5 c/d方波，测试贴片的宽度为1.0°，高度为0.5°或3.0°。高度为0.5°的测试贴片与共线杆的接触更广泛，高度为3.0°的测试贴片与侧翼杆的接触更广泛。共线（或侧翼）条的亮度假定为3.2至124.8 cd/m2的20个值，而侧翼（或共线）条的亮度保持为白色（124.8 cd/m2）或黑色（3.2 cd/m2）。在这些条件下，共线和侧翼酒吧的影响被认为是纯粹的对比度的方向。该效果由来自共线条的对比度主导（这导致白色效果），然而，侧翼条的影响也在对比度方向上。数据阐明了共线和侧翼条之间的亮度关系，其产生与白色效应相关的行为以及与类似于同时对比度的“反向白色效应”相关的行为。
In White’s effect equiluminant test patches placed on the black and white bars of a square-wave grating appear different in brightness. The illusion has generated intense interest because the direction of the brightness effect does not correlate with the amount of black or white border in contact with the test patch, or in its general vicinity. Therefore, unlike brightness induction effects such as simultaneous contrast, White’s effect is not consistent with explanations based on contrast or assimilation that depend solely on the relative amounts of black and white surrounding the test patches. We independently manipulated the luminance of the collinear and flanking bars to investigate their influence on test patch matching luminance (brightness). The inducing grating was a 0.5 c/d square-wave and test patches measured 1.0° in width and either 0.5° or 3.0° in height. Test patches measuring 0.5° in height had more extensive contact with the collinear bars and test patches measuring 3.0° in height had more extensive contact with the flanking bars. The luminance of the collinear (or flanking) bars assumed twenty values from 3.2 to 124.8 cd/m2, while the luminance of the flanking (or collinear) bars remained white (124.8 cd/m2) or black (3.2 cd/m2). Under these conditions the influence of the collinear and flanking bars was found to be purely in the direction of contrast. The effect was dominated by contrast from the collinear bars (which results in White’s effect), however, the influence of the flanking bars was also in the contrast direction. The data elucidate the luminance relationships between the collinear and flanking bars which produce the behavior associated with White’s effect as well as that associated with “the inverted White effect” which is akin to simultaneous contrast.
