Effect of Observer Elevation on the Moon Illusion by James Edward Hamilton Pdf
A study was made to determine if an increase in elevation of an observer above terrain causes a change in the magnitude of the moon illusion and estimation of distance upon terrain. A comparison was made to determine a relationship between the magnitude of the illusion at different observer elevations and the corresponding estimation of distance. It was found that a general decrease in the magnitude of the moon illusion coincides with a general increase in estimated distance when an observer ascends from a point above a terrain. Evidence is lacking to support the apparent-distance theory when an observer ascends above terrain.
