Explaining the moon illusion.
An old explanation of the moon illusion holds that various cues place the horizon moon at an effectively greater distance than the elevated moon. Although both moons have the same angular size, the horizon moon must be perceived as larger. More recent explanations hold that differences in accommodation or other factors cause the elevated moon to appear smaller. As a result of this illusory diff...
متن کاملMoon Illusion and Emmert's Law.
The perceived size of an afterimage varies with the part of the sky to which it is projected in a manner predictable from Emmert's Law and the appearance of the sky as a flattened dome. This effect is directly analogous to the moon illusion.
متن کاملPerceptual distance and the moon illusion.
The elevated moon usually appears smaller than the horizon moon of equal angular size. This is the moon illusion. Distance cues may enable the perceptual system to place the horizon moon at an effectively greater distance than the elevated moon, thus making it appear as larger. This explanation is related to the size-distance invariance hypothesis. However, the larger horizon moon is usually ju...
متن کاملEmmert's Law and the moon illusion.
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 visu...
متن کاملA New Explanation for the Moon Illusion
The mystery of the Moon illusion is still unsolved, even though various explanations have been offered over thousands of years. Here it is proposed that the illusion may be ascribed to an unusual optical atmospheric effect. The considerably thick spherical atmosphere may form a natural convex lens to converge light rays, which leads to the situation that the light rays from the Moon are greatly...
