较大的物体看起来比较小但其他方面相同的物体重。然而，当被举起和被看到时，更大的物体感觉更轻（大小-重量错觉），这证实了视觉大小和重量之间的关联具有感知成分。较暗的物体看起来也比较亮但在其他方面相同的物体重。然而，我们不确定这种联想是否也有感知的因素，或者它是否仅仅反映了这样一个事实，即至少在英语中，表面亮度和重量都被贴上了相同的口头标签（光）。为了解决这个问题，我们寻找一种相当于大小重量错觉的亮度。配对比较判断的重量得到不同的球只有颜色。仅根据视觉，较暗的物体被判断为较重。当球被举起以及被看到时，这种关联被逆转（即，亮度-重量错觉），与其具有感知成分相一致。为了测量错觉的强度（以克为单位），将一个白色和一个黑色球（均为129克）分别与一组重量不同的中灰色球进行比较。当球被称重和观察时，感觉白色球比黑色球重约8 g，差异对应于它们实际重量的6.2%。表面亮度和重量之间的关联可能的环境起源被认为是。
Bigger objects look heavier than smaller but otherwise identical objects. When hefted as well as seen, however, bigger objects feel lighter (the size-weight illusion), confirming that the association between visual size and weight has a perceptual component. Darker objects also look heavier than brighter but otherwise identical objects. It is uncertain, however, if this association also has a perceptual element, or if it simply reflects the fact that, in English at least, the same verbal label (light) is applied to both surface brightness and weight. To address this, we looked for a brightness equivalent of the size-weight illusion. Paired-comparison judgments of weight were obtained for balls differing only in color. Based on vision alone, darker objects were judged to be heavier. When the balls were hefted as well as seen, this association was reversed (i.e., a brightness-weight illusion), consistent with it having a perceptual component. To gauge the strength of the illusion (in grams), a white and a black ball (both 129 g) were each compared against a set of mid-gray balls varying in weight. When the balls were hefted as well as seen, the white ball felt approximately 8 g heavier than the black ball, a difference corresponding to 6.2% of their actual weight. Possible environmental origins of the association between surface lightness and weight are considered.
