A cognitive account is offered of puzzling, though well known phenomena, including increased size of afterimages with greater distance (Emmert's Law) and increased size of the moon near the horizon (the Moon Illusion). Various classical distortion illusions are explained by Size Scaling when inappropriate to distance, 'flipping' depth ambiguity being used to separate botton-up and top-down visual scaling. Helmholtz's general Principle is discussed with simpler wording - that retinal images are attributed to objects - for object recognition and spatial vision.
本文从认知角度解释了一些令人费解但广为人知的现象，包括后像随距离增加而变大（埃默特定律）以及地平线上月亮看起来更大（月亮错觉）。各种经典的扭曲错觉可以通过大小缩放来解释，即当与距离不匹配时，利用“翻转”深度模糊来区分自下而上和自上而下的视觉缩放。文中以更简洁的表述讨论了亥姆霍兹的一般原理——视网膜图像被归因于物体——用于物体识别和空间视觉。
