Rate of Apparent Magnification as a Cue to Distance: Laboratory Investigation,

A laboratory study was conducted to determine the extent to which an observer can use magnification of an unknown object as a reliable cue to its range or distance. Perceptual style was used as a source of variance. It was concluded that, when both initial sizes and both high and low velocity were presented, size alone was used to determine judgment of distance, although rate of magnification as a primary cue to distance cannot be eliminated on the basis of the present experiment.
