Abstract
The effect of shadow sharpness and shadow shape on the perception of spatial relationships was studied in three psychophysical experiments. In each experiment, the accuracy with which subjects were able to perform spatial estimation tasks was measured while either the sharpness or shape of the shadow was varied.
The effects of shadow sharpness and shadow shape on the accuracy of size and position estimations were tested in the first and second experiments respectively using fixed scaling tasks. Neither variations in shadow sharpness or shadow shape had a significant effect on the accuracy of performance in the experiments.
