Misschien interessant om weten dat de Amerikaanse experimentele psycholoog Edwin G. Boring ook onderzoek deed i.v.m. de oorzaak van de maanillusie. Zie het Engelstalig Wikipedia artikel omtrent Edwin G. Boring.
Moon illusion research
One of Boring's best-known projects is his 1940 study of the moon illusion. Boring and fellow researcher A. H. Holway hypothesized that the moon appears larger on the horizon because the eyes view it directly at a leveled position, while the moon overhead appears smaller because the eyes must look up. They tested this experimentally, and found that for an observer whose eyes were kept in a fixed position while a circle representing the moon moved up (through the use of a pulley system), the moon appeared to increase in size. This illusion did not occur when participants were lying down while viewing the moon, and they also found some evidence of it not occurring when viewing the moon with only one eye. These results led the researchers to conclude that the illusion of moon shrinkage depends on the movement of the eyes in the head, not the movement of the actual head, and that it depends on binocular vision, that is, the use of both eyes together. This study exemplifies Boring’s interest in misperceptions of sensory experience.
