Abstract

Relative size judgments were collected for two objects at 30.5 m and 23.8 m from the observer in order to assess how performance depends onthe relationship between the size of the objects and the eye level ofthe observer. In three experiments in an indoor hallway and in one experiment outdoors, accuracy was higher for objects in the neighborhoodof eye level. We consider these results in the light of two hypotheses. One proposes that observers localize the horizon as a reference forjudging relative size, and the other proposes that observers perceivethe general neighborhood of the horizon and then employ a height-in-visual-field heuristic. The finding that relative size judgments are best around the horizon implies that information that is independent of distance perception is used in perceiving size.
