当成年人观看嵌入在较高亮度环绕声中的测试光盘时，光盘的感知亮度很大程度上取决于环绕声与光盘 (S/D) 的亮度比（瓦拉赫比率规则）。使用强制选择新奇偏好技术测试的 4 个月大婴儿的表现与基于 Wallach 比率规则的预测一致。这一结果表明，提取和维护有关局部亮度比的信息的能力在婴儿期早期就存在。这种能力可能有助于亮度恒定性的发展。
When adults view a test disk embedded in a higher-luminance surround, the perceived lightness of the disk is largely determined by the surround-to-disk (S/D) luminance ratio (Wallach's ratio rule). Performance of 4-month-old infants tested with a forced-choice novelty-preference technique was consistent with predictions based on Wallach's ratio rule. This result suggests that the ability to extract and maintain information about local luminance ratios is present early in infancy. This ability is likely to contribute to the development of lightness constancy.
