Kaufman and Rock (1962) and Rock and Kaufman (1962) concluded that the moon illusion is a function of and attributable to apparent distance. They also reported a large framing effect as an exception. Analysis of the effect suggests two components which can account for the illusion independently of apparent distance. These are apparent size contrasts of visual images of discriminable features or objects of the earth with the moon's image and size constancy of the features or objects plus the interactions of the two. Apparent distances to horizons are always a consequence of the necessary conditions for the illusion. They are related to the illusion but are not a determinant of it.
考夫曼和罗克（1962年）以及罗克和考夫曼（1962年）得出结论，月错觉是视在距离的一种函数，且可归因于视在距离。他们还报告了一个作为例外的大框架效应。对该效应的分析表明有两个因素，它们可以独立于视在距离来解释这种错觉。这两个因素是地球上可辨特征或物体的视觉图像与月球图像的视在大小对比，以及这些特征或物体的大小恒常性加上两者的相互作用。到地平线的视在距离始终是产生这种错觉的必要条件的结果。它们与错觉有关，但不是错觉的决定因素。
