Abstract
The hypotheses that size judgments of unfamiliar objects are affected by distance information, and distance judgments by size information, were tested. Subjects made size or distance estimates in a cue-reduced situation, with or without distance or size information, and also made calibrated estimates in full-cue conditions. Size judgments in the no-information condition were correlated with the retinal image, whereas distance information produced size estimates closer to the actual size of the objects. Subjects given no information about size produced distance estimates that were randomly distributed, whereas size information yielded a weak effect in the appropriate direction. Implications for the size-distance invariance hypothesis and the specific distance tendency are discussed.
