Apparent rarefaction in subjective figures seems to violate the principle of size scaling. It has been claimed that this anomaly is due to a difference in illusory lightness which counteracts the expected effect of illusory depth. Qualitative evidence is presented that neither illusory lightness nor illusory depth have a relevant part in the phenomenon. An alternative account, in which contrast and size are shown to play major roles, is presented and discussed.
主观图形中明显的稀疏现象似乎违背了大小缩放原则。有人认为这种异常现象是由于虚幻明度的差异抵消了虚幻深度的预期效果。本文提供了定性证据，表明虚幻明度和虚幻深度在该现象中均不发挥相关作用。本文提出并讨论了另一种解释，其中对比度和大小被证明起着主要作用。
