在白色的显示中，被黑色包围的灰色目标比被白色包围的灰色目标看起来比被白色包围的相同物理亮度的目标更暗。随后的几项研究表明，这种效应只发生在测试区域的亮度介于诱导条纹的最小和最大亮度值之间时。当目标比两个诱导条纹都亮或暗时，效果的方向会反转，这种效果被称为“反转”白色效果。对于经典和倒置的白色效应是由共同的还是单独的潜在机制介导，人们的看法存在分歧。我们改变了经典和反向白色效应中测试和诱导区域的纵横比。与以前报道的结果一致，我们圆的经典效应的方向并不依赖于与测试贴片直接接触的黑色或白色边界的量。另一方面，感知亮度的倒置白色的效果受到这种变化，这表明在经典和倒置白色的配置诱导是由不同的机制。这些结果证实了亮度和几何关系之间的相互作用在诱导亮度的关键重要性。
In White's display the gray target surrounded more by black than white appears darker than the target of the same physical luminance surrounded more by white than black. Several subsequent studies have shown that this effect occurs only when the luminance of the test regions lies between the minimum and maximum luminance values of the inducing stripes. With targets either lighter or darker than both inducing stripes, the direction of the effect is reversed and the effect is known as the 'inverted' White's effect. Views differ on whether the classical and inverted White's effects are mediated by common or separate underlying mechanisms. We varied the aspect ratio of the test and inducing regions in the classical and inverted White's effects. Consistent with previously reported findings, we round that the direction of the classical effect did not depend on the amount of black or white border in immediate contact with the test patch. On the other hand, perceived lightness in the inverted White's effect was affected by such variations, suggesting that induction in classical and inverted White's configurations is governed by different mechanisms. These results confirm the critical importance of the interaction between luminance and geometric relationships in induced brightness.
