How do we estimate the relative size of human figures when seen on a photography
Original language description
We introduce a novel method for measuring size constancy in which subjects are asked to set the size of one person on the scene so it would correspond to the size of the same person in the photograph positioned in different egocentric distance and, at the same time, it would fit into the scene. Overall performance in the experiment was found to be rather precise and accurate. Still, size judgments were influenced by the relative order of the persons? distances as well as by the camera position. When human figures were seen from below, the subjective horizontal was raised and, consequently, the size of the closer person was set smaller and the size of the further person larger in comparison with the actual size. This tendency was reversed when figures were seen from above (ie the subjective horizontal was lowered). These findings are consistent with those of O?Shea and Ross (2007 Perception 36 1168?1178).
